And then, we make quantum mechanical generalization of some typical thermodynamic processes, such as isothermal process, isochoric process.
通过对一些基本的热力学过程的量子力学推广，我们可以直接从量子力学去理解热力学。

Another difference between isobaric and isothermal processes is that, since temperature is held constant in isothermal processes, the internal energy of the ideal gas can't change.
压力介电和介电工艺之间的另一个区别 热量是因为热量是恒定的。
Crash Course 综合篇
Well, remember how we described isothermal processes last time: In those cases, there are only very tiny differences in temperature, and they’re immediately eliminated.
好吧，请记住我们上次如何描述等温过程：在那些情况下，温度差异非常小， 并且会立即消除。
Crash Course 综合篇
During those isothermal processes, the temperature has to be kept constant while heat is transferred – which only works if the heat is transferred super slowly.
在这些等温过程中，温度必须在传递热量时保持恒定——只有当热量传递速度非常慢时才有效。
Crash Course Physics 速成课物理
An isothermal process is kind of like an isobaric process, in that if you add heat, the volume will expand, so the system will do work.
介电工艺类似于介电工艺 压力，当你加热时体积会增加。

等温过程
等温过程是热力学过程的一种，其中系统的温度不变：ΔT = 0。一个系统与外界的热源（热浴）接触，而过程进行得足够缓慢，使得系统不断通过热交换把温度调整为与热源的温度相同，则这个过程就是等温过程。还有另一种情况，如果系统与外界没有热交换（Q = 0），则称为绝热过程。
考虑一个理想气体，温度只与内能有关，是分子的平均动能的函数。如果内能不变，温度也不变。设物质的量（n）为常数。
根据理想气体状态方程，这意味着：

Isothermal process 等温过程
An isothermal process is a change of a system, in which the temperature remains constant: ΔT = 0. This typically occurs when a system is in contact with an outside thermal reservoir (heat bath), and the change occurs slowly enough to allow the system to continually adjust to the temperature of the reservoir through heat exchange. In contrast, an adiabatic process is where a system exchanges no heat with its surroundings (Q = 0). In other words, in an isothermal process, the value ΔT = 0 and therefore ΔU = 0 (only for an ideal gas) but Q ≠ 0, while in an adiabatic process, ΔT ≠ 0 but Q = 0.
