狭义相对论中的可变换假设与极限速率

THE TRANSFORMABLE POSTULATE IN THE SPECIAL RELATIVITY AND THE MAXIMUM VELOCITY

指出了狭义相对论中除了相对性原理和光速不变原理之外隐含的一条重要假设———可变换假设.证明了可变换假设与极限速率假设的等价性,从而说明了“光速是极限速率”是狭义相对论的假设,而不是狭义相对论的结论,并且这个假设没有得到可信的实验证明.

Besides the principle of relativity and the postulate of that the speed of light is invariant, the third postulate, the transformable postulate, is found in Einstein＇s special relativity. The equivalence between the transformable postulate and that the speed of light is the maximum velocity is proved in this article. It is also pointed out that the speed of light is the maximum velocity is a postulate, not a conclusion of the special relativity as usually believed; which is not confidently proved by experiment.
