According to the applicable scope, it is divided into general accounting software and special accounting software.
According to the hardware structure, it is divided into single-user accounting software and multi-user (network) accounting software.
According to the function, it is divided into accounting software, management accounting software and decision accounting software.
What types of software are there? The software system of a computer consists of system software and application software. The system software consists of operating system, language compiler and database management program. Application software includes word processing software, media playing software, CAD software, information management software, etc.
What are the types of clouds? (1) cirrus cloud
Thin and scattered, with fibrous tissue, such as feathers, loose hair or ponytails, hanging high without clouds, orange or red at sunrise and sunset.
Cirrus is the tallest cloud. It appears before the sun reaches the horizon in the morning.
(2) cirrostratus
It is the highest and whitest cloud curtain. When the sun or moon is covered, its outline can still be seen, and a halo often appears around it. There must be cirrocumulus in the dizzy place, but the thick cirrocumulus is pulled to the horizon like a curtain.
(3) cirrocumulus
This kind of cloud rarely appears and occasionally covers the whole day. Fishermen call it mackerel day, because the sky seems to be covered with fish scales, and the individuals are small, white and cloudless, and sometimes wavy. Cirrocumulus mostly appears at the same time as Cirrus or cirrostratus.
(4) Stratospheric clouds
Most of the high-level clouds are covered all day, and when they gradually become thick and low, people feel gloomy. There is usually a light rain before it becomes a cumulonimbus cloud.
On the contrary, cumulus clouds also rose in nimbostratus.
(5) Cumulus clouds
The individuals of the altocumulus are larger than those of cirrocumulus, with clouds in the center, which are often connected into one piece, with wavy bottoms, long rows, or checkerboards, with many styles.
(6) Stratocumulus
Individuals are larger than cumulus clouds, with softer appearance and less obvious structure. If connected together, there are wavy lines and alternating gray shadows at the bottom.
Stratocumulus clouds are mostly like giant rollers, and the bottom of the clouds represents the nest layer. The common sea of clouds in mountainous areas is mostly stratocumulus.
(7) Stratus clouds
Stratocumulus is a uniform gray-white low cloud that looks like fog, but does not touch the ground. When shrouded in the middle of the mountain, the edge has a downward posture, and there is dense fog.
(viii) nimbostratus.
It is a typical bad weather cloud, dark, amorphous, like broken, making the sky dark. Anything that belongs to sustainability must fall on nimbostratus.
(9) Cumulus clouds
It looks like a pile of cotton, with a bumpy top and a bulge like a mound, cauliflower or tower. When the sun shines obliquely, the bright and dark sides of cumulus clouds are obvious. if
In the same direction as the sun, the center is dark and the edges are particularly bright.
(10) Cumulonimbus clouds
It is the densest and largest cloud, with extremely high vertical extension and dark bottom, which is difficult to distinguish. The top rises like a mountain or tower, and there are often anvil-shaped pseudo-cirrus clouds that protrude like giant feather fans. When the cumulonimbus clouds reach the zenith, there will be a thunderstorm soon.
What kinds of cats are there? Cats are good companions of human beings.
On the earth where humans live, cats are everywhere.
Adult cats change their hair alternately in spring, summer, autumn and winter every year to adapt to climate change.
All kinds of domestic cats, especially castrated cats and kittens, are lively and active, like to simulate the game of catching mice, and often can perform many pleasing "programs" under the teasing of people. When the owner touches it with his hands, he often stretches his back and lifts his tail, and walks back and forth, accompanied by a low and persistent sound similar to a lullaby. When a cat is angry or frightened, it has a behavior pattern, that is, its thick hair hangs upside down, its teeth are exposed, and its thick tail swings from side to side. However, cats and dogs can't be friendly forever. Once they meet, especially strange dogs, they will bow their backs and stare at each other, hissing or screaming. When the dog approaches it, if there are trees or stakes nearby, it will climb immediately, and walking is the best policy. Otherwise, it will stick out its claws at its toes and pounce on the dog like lightning. Sometimes, its courage really surprises people.
Cat's character
Cats like to move around freely by themselves. Except for estrus mating, they rarely live together in groups of three or five.
Cats are not born to recognize a particular owner. However, when cats are kept in a family for a period of time, with the care, training and adjustment of their owners, their lonely habits can also be changed, and finally they can establish feelings with their owners; In this process, it will establish a concept of its own territory for its owner's family and surrounding environment, and will not let other cats enter its territory. Once there is an intruder, it will attack immediately.
Cats are very jealous, which shows that they will not only be jealous of similar pets, but sometimes their owners' excessive love for their children will also cause cats' indignation. For example, if you pick up one of the two cats, the other cat will immediately make a "whoop" threat, and the cat in your arms will not be outdone, preventing the other cat from approaching its owner.
Cats are "unsociable" and one of the most hygienic animals. Cats have to wash their faces with their paws several times a day; Every time you urinate in a fixed place, cover the feces with soil after defecation. Cats don't have the habit of defecating everywhere. Therefore, the owner can put bedding (such as sand, sawdust, broken absorbent paper and coal ash) in the bedpan. ) indoors or in a corner of the feeding cage (with a large space), it is convenient to collect all the urine and feces to keep the environment clean.
Cat's athletic ability
Cats are small, but muscular and contractile. There was almost no sound when they walked.
Cats are very alert. They are always alert to the slightest sound or potential danger. It always tries to put itself in a favorable position. Once it has the initiative, it will quickly attack and extend its claws to attack its prey.
Cats are the most patient animals. In order to catch prey, they often crouch in the dark, half squinting and waiting for the arrival of prey.
Cats are good at climbing high, mainly because of their claws In most cases, when a cat comes down from a height, it doesn't slide down, but jumps down directly. When cats walk on high and narrow objects such as fences or fences, they always tilt their tails high, just like the tail of an airplane, to keep their balance.
The cat is Nocturnal Animals, who likes to move at night.
Cats are nocturnal animals. Both domestic cats and wild cats have the habit of staying at home during the day and going out at night. Many activities (such as catching mice and courtship and mating) are often carried out at night. Cats are most active at dawn or evening every day, and spend most of the day relaxing or spitting. The time to raise cats should also be arranged at night, which can ensure a high success rate.
The habit of cats going out at night is mostly disliked by cat owners, especially in cities. It's annoying to find a female cat for a partner at night and a male cat for a partner. Although the cat is Nocturnal Animals, unlike mice and rabbits, cats don't want to hide in dark corners during the day, but are willing to lie on a bright and warm height and rest, climbing high and looking far, so as to find prey or deal with emergencies.
Cats like to sleep.
Sleep is an indispensable behavior of animals. Sleep can relieve physical and mental fatigue and prepare physical strength and energy for the next activities.
Cats sleep about twice as long as people. But cats don't sleep in concentration like people, but in several times, so cats can get up at any time at night. Lions are the leaders of cats and sleep for about 20 hours every day.
Studies have shown that three-quarters of cats' sleep is fake sleep, which is a nap. So, it seems that cats sleep 16 hours a day, but actually only sleep for 4 hours.
People sleep in various postures, and cats sleep in various postures just like people. Cats sleep on their stomachs, sit down and sometimes sleep on their stomachs. Cats can also talk in their sleep. This is called chirping. Cats wake up from nightmares. Open your eyes.
Cats are very careful about where they sleep. In summer, cats can accurately find a ventilated and cool place. In winter, cats can accurately find warm places. In addition, the cat also moved the sleeping place many times with the movement of the sun. Just like sunflowers always face the sun.
Cats always strive for the most comfortable place to sleep. For example, sleeping near a heating stove often burns the cat's tail; Sometimes the mother cat and cub will choose a comfortable place to sleep together, but it is easy for the kitten to suffocate and die; Sometimes cats step on furniture and things to find a good place to sleep. These cat owners must pay attention.
The cat is timid but curious.
Cats are timid, and even when resting or sleeping, they are in a state of high vigilance. As soon as the cat hears a slight sound or sees something strange, it will immediately open its eyes, stare at it, get ready to run away at any time, and then slowly leave until it is judged that there is no threat to it. When encountering strange and non-threatening things, cats often curiously use their front paws to test and fiddle with them.
Cats are naturally clean.
Among domestic animals, cats are the most hygienic. Cats like to live in a clean, warm, dry and bright environment.
Cats always comb their fur clean whenever and wherever they are, especially after eating, putting on the bedpan, or accidentally stepping on a dirty and wet place. They always calm down and lick themselves with their tongues. In fact, cat licking has another important physiological function. Cat licking fur can not only stimulate the secretion of sebaceous glands, make hair bright and smooth, but also lick a small amount of vitamin D to promote the normal development of bones. In addition, after being fluffy, it can also promote heat dissipation. This is not difficult to understand as long as you can notice when the cat combs its fur. Cats usually start to wash and tidy their fur after eating and playing, or after chasing their prey for strenuous exercise and waking up in the sun. In the hot season, many animals can give off heat by sweating. The sweat glands of cats are underdeveloped, so they can't evaporate a lot of water in their bodies, so cats use their tongues to smear saliva on their fur. The evaporation of water in saliva can take away heat and play a role in relieving summer heat and cooling down. Licking cats' hair during the depilation season can also promote the growth of new hair. In addition, by scratching and biting the coat, cats can prevent the coat from being infected with parasitic diseases, such as fleas and sheep diseases, and keep healthy.
In addition, cats never defecate anywhere, and generally have a fixed place to defecate. After defecation, they have to dig up the soil to cover up the feces. This "hygienic habit" of cats benefits from its ancestor wild cats. In order to prevent natural enemies from finding it and tracking it according to the smell of its feces, wild cats cover up the feces. This habit has lost its original meaning since it was spread to domestic cats, but it has given domestic cats a clean and hygienic name.
Cats are also very particular about food hygiene. The cat's food basin and water basin must be clean, otherwise, it may not eat or drink to protest.
What types of light emitting diodes are there? Light-emitting diode is called led for short. Made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc.
When electrons and holes recombine, they can emit visible light, so they can be used to make light-emitting diodes. Used as an indicator light in circuits and instruments, or as a text or digital display. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light and gallium nitride diodes emit blue light. Because of its chemical properties, it can be divided into organic light-emitting diode and inorganic light-emitting diode LED.
Classification:
Light emitting diodes can also be divided into ordinary monochromatic light emitting diodes, high brightness light emitting diodes and ultra-high brightness light emitting diodes.
Light Emitting Diode(LED)
Diode, color-changing LED, blinking LED, voltage-controlled LED, infrared LED, negative resistance LED.
There are two LED control modes: constant current and constant voltage, and there are many dimming modes, such as analog dimming and PWM dimming. Most LEDs are controlled by constant current, which can keep the LED current stable and not easily changed by VF, and can prolong the service life of LED lamps.
Ordinary monochromatic light emitting diode
Ordinary monochromatic light-emitting diodes have the advantages of small size, low working voltage, low working current, uniform and stable light emission, fast response and long life, and can be driven by various DC, AC, pulse and other power sources. As a current-controlled semiconductor device, a suitable current-limiting resistor needs to be connected in series.
The light-emitting color of ordinary monochromatic light-emitting diodes is related to the light-emitting wavelength, which in turn depends on the system.
Light Emitting Diode(LED)
Semiconductor materials for manufacturing light emitting diodes. The wavelength of red LED is generally 650~700nm, amber LED is generally 630~650 nm, orange LED is generally about 6 10~630 nm, yellow LED is generally about 585 nm, and green LED is generally about 555~570 nm. Commonly used domestic common monochromatic light-emitting diodes are BT (factory standard model) series, FG (Ministry standard model) series and 2EF series, as shown in Table 4-26, Table 4-27 and Table 4-28.
Commonly used imported common monochromatic light-emitting diodes are SLR series and SLC series.
High brightness monochromatic light emitting diode
High-brightness monochromatic light-emitting diodes and ultra-high-brightness monochromatic light-emitting diodes use different semiconductor materials from ordinary monochromatic light-emitting diodes, so their luminous intensities are also different.
Generally, materials such as aluminum gallium arsenide (GaAlAs) are used for high-brightness monochromatic light-emitting diodes, materials such as indium gallium arsenide (GaAsInP) are used for ultra-high-brightness monochromatic light-emitting diodes, and materials such as gallium phosphide (GAAP) or gallium phosphide (GAAP) are used for ordinary monochromatic light-emitting diodes.
See Table 4-29 for the main parameters of commonly used high-brightness red light-emitting diodes, and Table 4-30 for the main parameters of commonly used ultra-high-brightness monochromatic light-emitting diodes.
Color changing light emitting diode
Color-changing light emitting diodes are light emitting diodes that can change the color of light. Color-changing LEDs can be divided into two-color LEDs, three-color LEDs and multi-color LEDs (red, blue, green and white).
Color-changing LEDs can be divided into two-terminal color-changing LEDs, three-terminal color-changing LEDs, four-terminal color-changing LEDs and six-terminal color-changing LEDs according to the number of pins.
Commonly used two-color LEDs are 2EF series and TB series, and commonly used three-color LEDs are 2EF302, 2EF3 12 and 2E322.
Scintillation light emitting diode
Blinking light-emitting diode (BTS) is a special light-emitting device composed of CMOS integrated circuit and light-emitting diode, which can be used for alarm indication and undervoltage and overvoltage indication.
When using LED, it is not necessary to connect other components, just add an appropriate DC working voltage (5V) at both ends of its pin to flash.
Voltage controlled light emitting diode
Light Emitting Diode(LED)
Ordinary light-emitting diodes are current control devices, which need to be connected in series with current-limiting resistors with appropriate resistance. Voltage-controlled light emitting diode is a combination of light emitting diode and current limiting resistor, which can be directly connected in parallel at both ends of power supply. Make ordinary red light emitting diode
The voltage can work at 3 volts-10 volts, such as YX503URC, YX304URC and YX503BRC voltage source LED, which provides a greater choice for engineering and technical developers.
infrared emitting diode
Infrared light-emitting diode, also known as infrared light-emitting diode, is a kind of light-emitting device that can directly convert electric energy into infrared light (invisible light) and radiate it, and is mainly used in various lighting control and remote control transmission circuits.
The structure and principle of infrared light-emitting diodes are similar to those of ordinary light-emitting diodes, but the semiconductor materials used are different. Infrared light emitting diodes are usually made of gallium arsenide (GaAs), aluminum gallium arsenide (GaAlAs) and other materials, and are encapsulated with fully transparent or light blue or black resin.
Commonly used infrared light emitting diodes are SIR series, SIM series, PLT series, GL series, HIR series and HG series.
Battery LED lamp
Iviton has a built-in battery, which can make it glow for up to 3 hours. When there is electricity, the battery is charged and the light bulb emits light normally. In case of power failure, the light bulb will automatically switch to battery mode.
What types of spas are there? At present, in 2 1 century, spa is simply hydrotherapy, which uses situational therapy with five senses and six senses to achieve certain physical and mental effects. Spa is a kind of relaxation and maintenance therapy, also known as hydrotherapy in Chinese.
Spa is classified as follows:
1, beauty type
SPA(BeautySPA: This kind of spa mainly serves female customers. Most of them are for skin conditioning, body shaping and maintenance. Many spas in China are transformed from beauty salons.
2. Club type
SPA(ClubSPA: In Taiwan Province Province, most of these spas are membership-based, the main purpose of which is to keep fit and exercise, and to provide basic methods of using various spas. It has developed into a compound leisure center integrating massage, beauty and hydrotherapy, and the gym has also been incorporated into it, becoming a more extensive leisure center.
3. Hotel vacation
SPA(Hotel/ResortSPA: Combining the first-class hardware and service management of hotels and resorts, it provides customers with a spa that can completely relieve fatigue and enjoy another new feeling of complete relaxation, whether for business or leisure travel.
4. Hot spring type
Mineral spring SPA: located in a place with hot springs or cold springs. There are many hot springs in Taiwan Province, so soaking in hot springs is a kind of spa in general!
5. Hair
The latest fashion trends in Europe and America have spread to Asia. They improved the seats in traditional hair salons in space, separated them from the space, let the guests decide what services they want after consultation and suggestions, and help them relax by massaging with essential oil first, then massage and shampoo comfortably and gently, or further spa treatment, which are also collectively called HAIRSPA.
If a few years ago, few people in China knew what it was. Even if someone has heard of it, they just can't understand it and don't know why. Now, just look at the signs in the advertisements of spas and beauty salons that have sprung up on the street, and you can feel its heat. With people's more and more understanding of SPA, the consumption of SPA is becoming more and more rational, which makes the consumption group of small SPA smaller and smaller.
SPA is the abbreviation of Greek SOLUSPARAQUA, which means health in water. It means that people use natural water resources combined with bathing, massage and aromatherapy to promote metabolism, satisfy people's vision, taste, touch, smell and thinking, and achieve a kind of physical and mental enjoyment. If we seriously pursue the source of SPA, a leisure and beauty method, we will find that it has a very long history. It is reported that around the15th century, there was a small valley called Spau in Belgium in Europe, and there was a mineral-rich hot spring tourist resort in the valley. At that time, many dignitaries came here for vacation and recuperation, which was the original form of SPA. /kloc-After the 0/8th century, it became popular among European aristocrats and became the first choice for aristocrats to take vacations and keep fit. SPA fever revived in Europe and America in the 20th century, and was introduced to China at the end of last century.
When SPA landed in China beauty market, there were several ways for people in the domestic beauty industry to understand and operate it. At present, the authoritative point of view is that SPA is a soothing and decompression method composed of professional beauticians, water, light, aromatic essential oil, music and other elements, which can help people achieve physical, mental and spiritual bodybuilding and is an inevitable demand for modern urbanites to pursue physical and mental beauty. Modern SPA is a brand-new concept of health and beauty, which includes facial care, body care, hydrotherapy, massage, aromatherapy, facial features therapy and other relaxing activities, so that people can find a sense of belonging and inner harmony in stressful work.
What types of accounting items can be divided into? Accounting transactions, that is, accounting items can be divided into different categories according to different standards. According to the location of the transaction, it can be divided into external transactions and internal transactions, and according to the complexity of the transaction content, it can be divided into simple transactions and complex transactions.
What is Suixi? What are the types of happiness? What kinds of sentences praise the enemy with joy? The enemy is a persecutor, so you should be close to others. What is the reason? Why not rejoice and praise the three treasures and those who practice good dharma? Do you use this to show that you are virtuous? This is confusion, not correction! Do you know what Hanshan and Chide say about your persecutor?
Hanshan asked, "What should I do if someone slanders me, deceives me, humiliates me, laughs at me, belittles me, looks down on me and deceives me?"
Pickup replied, "Just put up with him, let him go, avoid him, put up with him, respect him, ignore him, stay a few more years, and you will see him."
Is there anyone here who likes and worships him? Learn Buddhism with wisdom, not blindly, or you won't get the benefits of Buddhism.
What kinds of running shoes are there? The classification here is mainly based on the user's requirements for the efficiency of running shoes and the purpose of wearing them. The differences mainly focus on the following points: a. the ability to support the arch and heel of the user, b. the ability to correct and protect the external splayed foot and the internal splayed foot, c. whether the sole is flat, d. the weight and stability of the shoes, and e. the road conditions at the running place.
Under such differences, running shoes can be divided into the following categories.
1, cushioning-This kind of running shoes is mainly suitable for runners who don't overemphasize arch support and heel correction. That is to say, if you have normal feet or splayed feet when you have a physical examination, and you have never had a serious ankle sprain accident. Moreover, the habit of running posture is generally that the forefoot touches the ground. Then, this type of running shoes is enough to provide you with a comfortable and elastic feeling. In addition, this kind of running shoes are generally light in weight, suitable for small size and beginners.
2. Stability-This kind of running shoes is mainly suitable for runners who need arch support and heel correction. For example, if you have slight splayed feet when running, or if your running posture habit is that your feet are behind the ground at every step, or if you have to run and exercise at least four times a week, each time the distance is more than 3 kilometers, then you need to give your feet some support and protection. Then these shoes should suit you better. The weight of this kind of running shoes is generally heavier than cushioning. It should be noted that most running shoes produced by various brands are cushioning or stable. This also shows that most runners have these two characteristics on the one hand. Moreover, the performance difference between these two kinds of shoes is relatively small.
3. Control exercise control-if you have proved that you have splayed feet when running (seriously), or your ankle strength is poor (for example, you sprained your ankle), or your weight is heavier than the standard weight, or your running posture is used to landing on all feet. Then, this kind of running shoes should be more suitable for you. It can provide more arch and heel support and posture correction than other kinds of running shoes, and prevent accidental injuries to some extent. However, compared with cushioning and stability running shoes, motion control is more important, which is of course proportional to its protection of footsteps and cushioning of vibration.
