So what they do is, they're describing how these thermodynamic properties change, in terms of only state functions and state variables.

他们的作用是描述,随着状态函数和状态变量的变化，系统的热力性质如何变化。

All right, so this is the heat flowing in or out of the system, and these are all functions of state.

好的，这就是系统的热量变化,这些都是态函数。

Only the operating system has controlling of byte zero NULL in the computer's RAM and so if a function ever returns null, aka zero, well, something must have gone wrong because that can't possibly belong to me that memory because by human convention zero is owned by the operating system; not by a program I wrote.

只用操作系统在内存中能够控制,字节0，并且如果一个函数返回，或者说0，好的，可能出错了,因为那可能是不属于我的内存,因为惯例上，0是由操作系统拥有的,而不是由我的程序拥有的。

And the equation of state, pressure versus volume at constant temperature, is going to have some form, let's just draw it in there like that.

系统的态函数，恒温下压强比体积，变化曲线，就像这样。

It's not going to be zero this time because we have non zero heat exchange between the system and the environment, right.?

热力学量，但是现在让我们看一下,我们的特殊函数，这次它不会是零,因为系统与外界的热量交换并不是零，对吧？

I don't need to know about a specific path here.

这只涉及系统的状态函数。

Anybody have an idea? What's the one function of state? I'm the system, the rest are the surrounding. What's the one function of state that's constant when I'm doing all my chemical reactions to move my arms around?

态函数又是什么呢？,我是一个系统，其余的是周围的环境,那么当我在做所有的化学反应,去四处移动我的手臂的时候,什么量是常数？

So we'd really like to be able to find some sort of equation of state, or some sort of rather function of state that's going to relate the heat going in or out of the system with that function of state, because this isn't going to do it.

所以我们真的想要去,找到一些态方程或者态函数,通过这个态函数可以表示热量,在系统与外界的交换,因为这个不能表示它。
