2. If it is necessary to measure the high-temperature dielectric constant and dielectric loss of ceramic materials, it is necessary to cooperate with the high-temperature test platform, high-temperature dielectric fixture and high-temperature dielectric temperature spectrum measurement system software to complete the measurement task, that is, a set of high-temperature dielectric temperature spectrum measurement system to complete the experiment. Only two parameters, capacitance c and dielectric loss d, need to be set on the instrument, and then the dielectric constant can be calculated by the size information of the sample (sample thickness and sample diameter).

3. The high-temperature dielectric temperature spectrum measuring system of Panax notoginseng is designed to meet the requirements of measuring the dielectric properties of materials in high-temperature environment. It consists of hardware equipment and measurement software, including high-temperature test platform, high-temperature test fixture, impedance analyzer and high-temperature dielectric measurement system software.

4. The high-temperature test platform provides a high-temperature environment for the sample; The high temperature test fixture provides a test platform for the sample to be tested; The impedance analyzer is responsible for testing each set of parameter data. Finally, the functions of these hardware devices are integrated by measuring software to form a set of temperature spectrum measuring system for Sanqi high-temperature dielectric, which integrates experimental scheme design, temperature control, parameter measurement, graphic data display and data analysis.
