| 摘 要： | 摩擦力做功转换为热,进而转化为系统的内能,三者乃同一能量的不同角色转换,不可重复计算,由此澄清了有关摩擦力做功的一个佯谬.此外,本文还提出了功能原理与热力学第一定律的一般形式.

| Abstract: | It is pointed out in this paper that the work done by friction is transformed into heat, and then into the internal energy of a system. All of them are only different forms of the same energy, so we can not take account of them repeatedly. Thus a paradox of friction work is cleared up. Besides, the general form of the principle of work andenergy and of the first thermodynamics law is given here. |
