time constant 是什么意思

中文翻译与英英解释

	(电子)时间常数。

	time: n. 1.时，时间，时日，岁月。 2.时候，时刻；期间； ...
	constant: adj. 1.恒定不变的，固定的，稳定的，恒久的；继续不 ...

	the ratio of the inductance of a circuit in henries to its resistance in ohms
	(electronics) the time required for the current or voltage in a circuit to rise or fall exponentially through approximately 63 per cent of its amplitude

In physics and engineering, the time constant, usually denoted by the Greek letter au (tau), is the parameter characterizing the response to a step input of a first-order, linear time-invariant (LTI) system.Concretely, a first-order LTI system is a system that can be modeled by a single first order differential equation in time.
