该模型的动态特性可由对偶微分方程描述，它具有从状态空间内任一初始点找出多个稳定平衡点的能力。

The dynamical property of this model is described by dual differential equations and it can find out several stable equilibrium points from any initial point in the state space.

本文首先建立了架空索道的动力学模型，并建立了它的振动微分方程、初始条件及边界条件。

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。

But instead in this chemistry course, I will just tell you the solutions to differential equations. And what we can do is we can start with some initial value of r, and here I write r being ten angstroms. That's a good approximation when we're talking about atoms because that's about the size of and atom.

但在这个课里，我会直接，告诉你们微分方程的解,我们可以给距离r一个初始值,我这里把r取10埃,当我们讨论原子时,这是一个很好的近似,因为原子的尺寸。
