相对性原理与时空线性变换THE PRINCIPLE OF RELATIVITY AND THE SPACE-TIME LINEAR TRANSFORMATION
戴又善
摘要(Abstract)：
惯性系具有任何方向时空平移不变的特性,依据相对性原理和时空平移不变性证明了惯性系的时空变换必须为线性变换。相对性原理是时空线性变换的真正必要条件。除了伽利略变换具有"同时的绝对性"外,其他的惯性系时空线性变换都具有"同时的相对性"。利用相对性原理还可以证明惯性系的速度变换为单调递增函数,因而存在速度上限,惯性系除伽利略变换外的所有时空线性变换都存在有限的极限速度,进而可以推导出惯性系时空线性变换的广义洛伦兹变换公式,其中极限速度的取值可以通过实验来确定。
