当温度出现阶跃变化时，仪表的电流输出信号变化至相当于该阶跃变化的50%所需的时间 ，通常以t0.5表示当温度变送器的阶跃响应；当稳定时间不超过热电偶(阻)热响应稳定时间t0.5的五分之一时，则用热电偶(阻)热响应时间作为仪表的热响应时间； 当温度变送器的阶跃热响应稳定时间不超过热电偶(阻)热响应稳定时间t0.5的二分之一时，则用温度变送器热响应时间作为仪表的热响应时间；
然后在微桥上溅射镍—铬电阻薄膜，形成温敏传感器微结构，并对其温度电阻特性，热响应时间进行了测量。
After sputtering with N-Cr, a microstructure of temperature-sensitive sensor was formed, and its character of R-T and thermal response time constant were measured.
在温度出现阶跃变化时，热电偶的输出变化至相当于该阶跃变化的50％所需的时间称为热响应时间，用T0.5表示。
Step change in temperature occurs when changes in the thermocouple output to the equivalent of 50% of the step change in the time required is called thermal response time, with T0.5 said.
特别注意不要使滤波器的响应时间在热曲线的峰值点引起误差。
Take care that the response time of the filter doesn't cause errors in the peaks of the heat curve.
