When the amplitude is modulated or changed, we hear this as a change in volume.

当振幅被调制或改变时，我们听到的是音量变化。

And a greater temperature change will lead to a greater change in volume.

它将推动温度的最大变化 使声音发生更大的变化。

So the work done during an isobaric process is equal to the pressure of the gas x the change in volume.

所以在解压过程中所做的工作 气体压力等于容器体积的变化。

Finally, some materials are more resistant to changes in volume -- and that stiffness is measured by the bulk modulus, represented by a capital-B.

最后，一些材料更能抵抗体积的变化——这种刚度是通过体积模量来衡量的，用大写字母 B 表示。

The equation for volume expansion just says that the change in volume is equal to the coefficient of volume expansion, times the initial volume, times the change in temperature.

体积膨胀方程只是说体积变化等于体积膨胀系数乘以初始体积再乘以温度变化。
