The hydraulic loading system is developed and used to study the frost heaving characteristics of the subgrade soils under dynamic loading in closed system and open system . On the base of these work, the conclusions are as follows:1. Because of the the fine-grained fill, the frost deformations of Beijing-Baotou railway subgrade and Baotou-Lanzhou railway subgrade are holistically irregular, and great discrepancies exist among the frost heavings of subgrade at different sections.

He sets out to prove that to punish the mad, the infant child or those who break the law unintentionally or under duress or even under 'necessity' must be inefficacious; but all that he proves is the quite different proposition that the threat of punishment will be ineffective so far as the class of persons who suffer from these conditions is concerned.

他试图证明惩罚疯子、法定未成年人或在受到胁迫的情况下无意识地乃至在"紧急避难"的情况下触犯法律的人[MSOffice1] ，必定毫无效果。但是，其所证明的却是这样一个完全不同的命题，即惩罚的威吓对那些处于此类状况下的人不起作用。

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。
