resistance-capacitance time constant

The characteristic of variation of resistance for Polysilicon microresistor with time was measured under constant power operation using Digital Constant Power System ( DCPS).

利用数字式恒定功率测试系统（DCPS）对多晶硅微电阻进行恒定直流功率负荷下电阻随时间变化特性的测量实验。

Transformer's DC resistance measurement is one of the primary item before transformer leaving factory and precautionary test. The inherent time constant of transformer is quite long, so it is very important to study how to shorten the measuring time.

电力变压器直流电阻测量是变压器出厂及预防性试验的主要项目之一，但电力变压器固有的时间常数较大，研究缩短电力变压器直流电阻的测量时间具有重要意义。

The constant creep rate and creep breaking elongation were increased and creep-resistance breaking time was decreased with the increase of room temperature.

随环境温度的升高，纤维的恒蠕变速率增大，抗蠕变断裂时间变小，蠕变断裂伸长变大；
