However, most of these investigations focused on the rotating beams or plates undergoing a prescribed large overall motion, where the effect of large overall motion of the reference frame on elastic deformation was considered but at the same time the beam's elastic deformation couldn't influence the large overall motion of the reference frame because the large overall motion is known a priori. In fact, this kind of problem on the dynamic stiffening is a structural dynamics problem in a non-inertial frame.

值得指出，上述这些研究工作都局限于大范围运动为已知情况下的非惯性系下柔性体的动力学性质，实质上是一个非惯性系下的结构动力学问题，只考虑了大范围运动对变形运动的影响，而没有充分考虑到大范围运动和变形运动之间的相互耦合作用，这种耦合作用是单向的。

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。
