Mechanism refers to the internal working mode of each element in a certain system structure and the operating rules and principles of each element in order to realize a certain function under certain environmental conditions.

At present, there are two explanations of mechanism: first, mechanism refers to the internal working mode of each element in a certain system structure and the operating rules and principles of each element interacting in a certain environment to achieve a certain function; Second, it refers to the reasons and reasons for things to change. From the concept analysis of mechanism, mechanism includes two aspects: formation factors and the relationship between formation factors.

In chemical kinetics, "mechanism" refers to describing the chemical process from the binding relationship of atoms. If the process is controlled by dynamics, then the mechanism refers to the surface process at the atomic level.

Working principle:

Basic laws of universal significance in natural science and social science. It is based on a lot of observation and practice, and it is obtained through induction and generalization. It can not only guide practice, but also be tested by practice.

Usually refers to the basic laws of universal significance in a certain field, department or science. The principle of science is based on a lot of practice, so its correctness can be tested and determined by experiments. Various specific theorems and propositions can be derived from scientific principles, which will play a guiding role in further practice.

Extended data:

The principle lies in the fundamental truth of things. Two different things may have the same principle. For example, the principle of water flowing downwards and sliding on the slide is gravity.

Mechanism is a scientific research method to find out the law of its development and change by analyzing the internal causes (mechanisms) of the system. This method is often used in combination with deduction in scientific research, which has played a great role in the history of scientific development. For example, the discovery of the law of gravity and the establishment of the theory of relativity. It can be said that almost all physical theories cannot be established without mechanism analysis.
