温度计的滞后时间,将会引起仪表的动态误差。当被测介质温度u随时间t的变化关系为u=f(t)时,则被测介质温度的变化速度为(du)/(dt)。若(du)/(dt)乘以时间常数τ时,我们来考察
Thermometer lag time, will cause the instrument dynamic error. When the measured medium temperature u changes with time t u = f (t), then the measured medium temperature change rate (du) / (dt). Let (du) / (dt) times the time constant τ
