这通常有助于允许系统的响应在采样周期结束之前自然衰减到零。

This can often help by allowing the response of the system to naturally decay before the end of the sample period.

三体船模型横摇试验包括静水中的自由横摇衰减试验、规则波中的零速横摇试验。

Free decay experiments were conducted in calm water at various model speeds and roll experiments in transverse regular waves at zero speed.

So, let's say we start off at the distance being ten angstroms. We can plug that into this differential equation that we'll have and solve it and what we find out is that r actually goes to zero at a time that's equal to 10 to the negative 10 seconds.

也就大约是这么多,所以我们取初始值10埃,我们把它代入到,这个微分方程解它,可以发现，r在10的,负10次方秒内就衰减到零了。
