s4: and obtaining the temperature of the concentrated sulfuric acid solution to be tested according to the relation curve of the temperature of the concentrated sulfuric acid solution and the dielectric constant change and the instant dielectric constant.
The step S2 "obtaining the real-time dielectric constant value of the dielectric resonator antenna by simulation software" specifically includes the following steps, S21: adjusting DK value of the model in the simulation software to enable the resonance frequency simulated by the model to be consistent with the resonance frequency obtained by the upper computer test, wherein at the moment, the simulated DK value of the model is the real-time dielectric constant value of the dielectric resonator antenna;
the step S3 "obtaining the instant dielectric constant of the concentrated sulfuric acid solution to be tested according to the real-time dielectric constant value and the initial dielectric constant value includes the following steps: subtracting the initial dielectric constant value from the simulated DK value of the model to obtain the instant dielectric constant of the concentrated sulfuric acid solution.
