Description

technical field [0001] The invention relates to the technical field of experimental detection, in particular to a device for testing the anisotropic conductivity of a fluid. Background technique [0002] Anisotropy means that all or part of the chemical and physical properties of a substance change with the change of direction, showing different properties in different directions. Anisotropy is a common property in materials and media. For example, liquid crystals and fibers have anisotropic electrical and optical properties. Testing and evaluating the electrical and optical properties of anisotropic materials and media in different directions is a problem often encountered in modern scientific experiments, and it is also a very important way to understand the physical properties of materials and media and develop new sensor devices. [0003] In the prior art, the Chinese utility model patent "Thermal Resistance Testing Device for Anisotropic Thermal Conductive Sheet" with ...
