读者赵利杰问:“热学中已有第一定律和第二定律,为什么还有第零定律,而其他物理定律却没有相应的第零定律呢?”这位读者讲的确实如此,这个事情也特别有趣!我们知道,力学中有第一、第二、第三定律,就没有所谓的牛顿第零定律.在直接回答这个问题之前,我们首先要了解热学中第一定律(热力学第一定律)和第二定律(热力学第二定律)的内容,它们 Readers Zhaoli Jie asked: “There is the first law of heat and the second law, why there is the first zero law, and other laws of physics but there is no corresponding zero law?” "The reader is true, this thing It is also interesting to note that we know that there is no so-called Newton’s Law of the zeros in the first, second, and third laws of mechanics and we must first understand the first law of heat (the first law of thermodynamics ) And the second law (the second law of thermodynamics), they
