有第零定律，这些定律中的每一条都定义了，热力学中一个基本物理量的概念，第零定律定义了温度。

There's a zeroth law the zeroth law every one of these laws basically defines the quantity in thermodynamics and then defines the concept.

热力学是一座，建立在这四条定律上的大厦，它是一门非常成熟的科学，也要求我们在定义东西时非常小心。

So thermodynamics, based on these four laws now, requires an edifice, and it 's a very mature science, and it requires that we define things carefully.

为了深入研究，我们在模型中采用离散热力学分析并定义了在机床导轨热控制中广义热阻的概念。

For the deep research, we apply the discrete thermodynamic analysis and define the concept of the virtual thermal resistance in the heat control of the machine tool guide.

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。
