If you're talking about tranquilizer darts, you're probably referring to the kind that are shot out of an air rifle using compressed gas, though they can also be fired from crossbows or blowguns.

如果您谈论是镇静剂飞镖，您可能指是使用压缩气体气步枪中射种，尽管们也可或吹气枪中发射。

The last process is the opposite of the second: it’s adiabatic, so the gas is compressed but its heat doesn’t change.

最后一个过程与第二个过程相反：是绝热， 所气体被压缩但热量不变。

The last process is the opposite of the second: it's adiabatic, so the gas is compressed but its heat doesn't change.

是静态 热，因此，气体被压缩，但温度是恒定。
