今天我还将跟你们讲这些,但今天的重点是,对上次口头表述内容中的热力学,第二定律,的数学推导,我们上次看到的。
I'll show those again, but what I want to do mostly today is try to put a mathematical statement of the second law in place that corresponds to the verbal statements that we saw last time.
本文在稳态模型和局域热力学平衡等假设下,推导了在纵向磁场下真空电弧压力的数学表达式。
This paper derives the mathematical express on of the pressure of vacuum arc subjected to an axial magnetic field under stationary model and the assumption of local thermodynamic equilibrium etc.
而第三种选择:世界是永恒的,没有起源,但这违背自然法则,如热力学,并已由20世纪的数学确定性证明非真。
A third option, the world is eternal and without origin, contradicts Natural Laws such as Thermodynamics and has been disproved with mathematical certainty in the 20th century.
This is an abstract and powerful mathematical statement of the first law of thermodynamics.
这是热力学第一定律的一个抽象,而且具有很强数学性的表述。
I'll show those again, but what I want to do mostly today is try to put a mathematical statement of the second law in place that corresponds to the verbal statements that we saw last time.
今天我还将跟你们讲这些,但今天的重点是,对上次口头表述内容中的热力学,第二定律,的数学推导,我们上次看到的。
People have done experiments through the ages, and they've accumulated the knowledge from these experiments, and they've synthesized these experiments into a few basic empirical rules, empirical laws, which are the laws of thermodynamics.
很长的时期内,人们做了大量的实验,从这些实验中积累知识,将这些实验总结成一些基本的经验法则和定律,这就是热力学的定律,然后,人们给这些定律添加,数学架构。
