热力学定律

In chapter four, in order to study the micro-process of the compress of the high speed oil-free twin screw compressor, a mathematical model is built based on the conservation of mass and the first principle of thermodynamics.

第四章为了深入研究无油双螺杆压缩机的微观工作过程，以质量守恒定律和热力学第一定律为基础，建立了双螺杆工作过程的数学模型。

Week 9 Quantity of heat, work, internal energy in thermodynamics, first law of thermodynamics.

第9周 热力学的热量、功、内能；热力学第一定律及对理想气体等值过程的应用。

Clearly, a refrigerator, which is a physical system must obey not only the first law but the second law of thermodynamics as well.

很明显，冷冻机是一种物理系统，因此它不仅必须遵从第一定律，也必须遵从热力学的第二定律。

The first and second law of thermodynamics, as the universal rules in the nature, can be invoked to describe the energy dissipation.

热力学第一定律和第二定律作为自然界普遍适用的规律，能够用来描述能量耗散。

A relativistic transformation of generalized coordinates is discussed and it is found that the first law of thermodynamics and the equation of state of an ideal gas are invariant with respect to the relativistic transformation of generalized coordinates , so that the existence of relativistic transformation of generalized coordinates is reasonable.

讨论了一个涉及热力学的广义坐标的相对论变换，发现热力学第一定律和理想气体状态方程对广义坐标的相对论变换具有不变性，表明广义坐标的相对论变换有其存在的理由

It is a well-known scientific law -- the second law of thermodynamics.

这是一个众所周知的科学定律-热力学第二定律的。

This sounded remarkably similar to the Second Law of Thermodynamics, with area playing the role of entropy.

这听起来非常类似热力学第二定律，由于区域扮演热力学熵的角色。

The contradiction this causes is that any object with heat should eventually dissipate it's heat energy to its surroundings, and a white hole by definition never runs out of heat or mass, thus standing in violation of every other major law of physics we have in order to hold true to the second law of thermodynamics.

反驳的理由就是任何热的物体最终会使它的热能散发到它周围的环境中，而定义的白洞从来不会失去热能或质量，这样就面临违反了所有我们已经适用的热力学第二定律其它物理学大定律。

Therefore, the unattainability of absolute zero is an independent law.

由热力学第二定律可导出可逆过程和无法使温度降到绝对零度，但对于不可逆过程则无法导出，因而绝对零度不能达到是一条独立的定律。

Based on the first law of thermodynamics and the law of mass conservation, a thermodynamic model of the back-pressure cavity has been developed by considering influence by back pressure cavity, compression chamber and oil supply system.

本文在热力学第一定律及质量守恒定律的基础上，建立了背压腔的热力模型，模型详细考虑了背压腔与工作容积、压缩机内油路之间的联系，并通过他们之间的联系给出了背压腔压力的计算方法。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
