摘要
阐明狭义相对性原理的准确含义，指出它并不要求自然界每条定律都单独协变，但要求每条定律至少属于一个协变集合．给出最小协变集的求法．表明机械能守恒定律满足狭义相对性原理及其对自然界定律的协变性要求．还指出一切社会科学定律也都满足狭义相对性原理．
The exact meaning of the principle of special relativity are explained. It is pointed out that according to the principle of special relativity,every law of nature is not co-variant by itself,but belongs to a set of co-variance at least. The method of finding minimum sets of co-variance is given. The conservation law of mechanical energy is proved to be satisfactory for the principle of relativity and its requirement for the co-variance of the laws of nature.All the laws of social science satisfy the principle of special relativity too.
