(Continued from page 205) humidity and fix the problem, adjust the humidity of the environment and detection are difficult, so heat flow meter humidity correction method experimental data and there is no effective method. The impact of dust, heat probe if the long-term work environment in the air with dust, the probe surface will be contaminated, the heat dissipation will also change, thus changing the flow of the output characteristics. However, the amount of the specific impact of the data currently can not be described. 【Reference】 Sichuan Tianyu Lang. Flow Measurement Handbook [M]. Beijing: China Measurement Press ,1982:231-239.
