And I am not going to take the time to solve it because I think that is a waste of class time, but those are the three unknowns.
但我并不打算把解这几个方程,我觉得那会是浪费课堂时间,但那是三个未知式。

It literally halves the amount of time it takes to solve that problem but we can actually do better.
它能把解决问题时间的缩短一半,但其实我们能做的更好。
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。
