I point out that mechanics does not provide adequate foundation for the description of all natural phenomena. We should have a new understanding that in the 'change of location' of the same event of inertial system there exist two different reference systems that are mutually in uniform rectilinear motion. This new understanding will avoid the puzzle brought about by physicists' obscure yet obdurate conception as to which of the two mutually uniformly moving reference systems is not related to the inertia reference system.

我指出力学为一切自然现象描述所提供的基础是不够充分的,重新认识惯性系的同一事件"位置的改变"存在着两个互相匀速直线移动着的两种不同参考系,可以避免物理学家们模糊、执着地认为惯性参考系究竟是用两个互相匀速移动着的参考系中哪一个无关所带来的困惑。
