固有时 meaning in English

intrinsic time
proper time

The intrinsic time delayed properties of system may lead to measurementdelays , but the time delays in measurement equations of this thesis are alwaysresulted from the signal transmission processing of the sensors which is used toobserve
观测时滞可能是由系统的固有时滞特性引起的,而本文中观测方程中出现时滞则往往是由于用于观测的传感器在信号传输过程中导致的滞后系统。
