温度装置中的表面温度传感器的数学模型进行了建模，分析了导热平板对被测表面温度传感器时间常数的影响，通过对不同时间常数的表面温度传感器进行数值仿真计算，得出当被测表面温度传感器时间常数大于20倍导热平板时间常数时，导热平板对被测表面温度传感器时间常数的影响可以忽略。 |

| The mathematical
model of surface temperature sensor in a step change surface temperature measuring device is established.The influence of the thermal conductive plate on the time constant of measured surface temperature sensor is analysed,through the mathematical simulation and calculation of surface temperature sensor at different time constants, it is concluded that when the time constant of thermal conductive plate is 20 times greater than that of the measured surface temperature sensor, it can be ignored that the influence of the thermal conductive plate on the time constant of measured surface temperature sensor. |
