constant-pressure change的意思|示意

The change in gas temperature that occurs when the gas is expanded at constant enthalpy from a high to low pressure.

当气体从高压到低压在等熵下膨胀时所产生的气体温度的变化。

Using a home-made constant-volume oxygen-bomb combustion apparatus, the change of gas pressure with combustion time of coal samples in oxygen-bomb were investigated.

在自制的定容氧弹燃烧装置上， 测量了多种煤样在氧弹内燃烧期间气体压力随燃烧时间变化的关系。

So I need, well the pressure is constant, but there's a change in volume.

压强不变，体积变化。

The darkness did not change, and neither did the constant pressure enfolding her.

黑暗毫无变化，包裹着她的持续的压力也是如此。

It's a state function, so we're at constant temperature and pressure, and now we want to consider some chemical change or a phase transition or you name it.

这就是态函数，我们处于恒定的温度和压强之下，然后考虑某些化学变化或者相变，或者你想考虑的东西。

If that changes, of course you know that the pressure in there is going to change at constant volume if the amount of gas in there is changing.

如果它发生了变化，当然在等体条件下，如果气体的总量，发生了变化，压强也会发生变化。
