The circulatory system which we'll talk about in a couple of weeks, the heart, the blood vessels, and the blood work together to form a totally internal function.

例如过几周我们要讲的循环系统,心脏,血管,血液,三者协同工作,形成一个完全在体内发挥作用的体系

So it's got an internal procedure,internal function, local to the unit test, that runs the simulation.

它有内部过程，内部函数，它对unit，test来说是有本地环境，来支持股票仿真程序的运行。

OK, now, we're going to look at the internal energy, and we're going to pretend that it is explicitly a function of temperature and volume.

好，我们接下来看看内能，我们假设,它是温度和体积的函数。

But it's allowed to say the internal energy is a function of temperature and volume.

但是我们也可以说内能,是温度和体积的函数。

We'll then look at the quantity, internal energy, which we define through the first law, and we think of it as a function of two variables T and V.

接下来我们考虑内能，这是由热力学第一定律定义的物理量，我们把它看作T和V的函数。
