摘要
光速不变原理是狭义相对论的两条基本原理之一。光速不变原理包含两点内容:①光速与光源运动无关;②光速不依赖于观察者所在参考系。文中讨论了这两点之间的区别。指出宋代超新星爆发事件只是有助于证明“光速与光源运动无关”,而不能证明整个光速不变原理;同时指出“光速与光源运动无关”不违反经典物理学中的伽利略变换。澄清了对光速不变原理的一些不清晰的认识。
One of the two basic principles of special relaxivity is the principle of constanay of light ueloeity. There are two main points in the principle of constancy of light velocity ： ①velocity of light is independent of movement of light source, ② velocity of light is independent of which reference frame the observer is in. Difference between these two main points is discussed in this paper. It is indicated that explosion of the supernova at the Song Dynasty is only conducive to prove the conclusion that velocity of light is independent of movement of light source but is not able to prove the whole principle of constancy of light velocity. Some dim understanding about the principle of constancy of light velocity is clarified.
