For a constant force, since this is a well-behaved--

对于一个恒力而言因为它很典型
the friction between here is well-known and well-behaved,

这里的摩擦力大家都很熟悉了
it's going to just slide with a uniform velocity

内部活塞会以一个恒定的速度
the inner cylinder over the outer cylinder.

滑出外部气缸
Does that make sense?

你们听懂了么
So, this dashpot is an idealized physical model for

所以该减震器是一个理想的物理模型
how a viscous liquid behaves.

能够解释粘性流体的特性
I apply a force and it continuously deforms.

施加一个作用力粘性流体将不断变形
Now, it's better as a thought experiment than a real experiment

想象的实验比真正的实验要好些
because you can imagine making things

因为你们能够想象出
that behave like real springs.

具有真实弹簧特性的东西
Real dashpots would be hard to make. Why?

很难做出真正的减震器为什么
