We have a table of the elements with properties varying periodically with atomic mass, so we compress all of that information and refer to it as the Periodic Table.

我们有一个元素表，其中的元素的特性,随着原子质量的改变而引起周期性的变化，所以我们将所有的信息精简,将它变成一个周期表。

You do it so quickly that the heat flow between the inside of the bicycle pump and the outside is too slow compared to the speed at which you compress.

我们用力很大,于是压缩得很快,打气筒内外热传递的速度,与之相比要慢得多。

Therefore, it'll compress by an unknown x, which is equal to mg divided by the force constant of the spring.

因此它的压缩量为 x,也就等于 mg 除以弹簧的弹性系数

But you don't compress it so quickly that you're not in there reversible process so you compress that if you were to feel the temperature of the air and you can feel it through the nozzle gives you an idea of the temperature of the air inside your bicycle pump.

但是压缩速度,也不能太快,否则就不是,可逆过程了,这样当压缩气体时,从喷嘴可以感受到,内部气体的温度。
