本文引入了等参单元形函数的几何变换思想，利用径向基函数，解决了复杂形状机翼的二维气动代理模型的构造问题，进行了某巡航导弹弹翼考虑结构变形的气动力代理模型的构建。

Instead the current Chengde synclinal basin is almost certainly the consequence of footwall deformation below the north-directed Chengde County thrust as indicated by (1)its northward-overturned geometry, and (2) the influx into the southern part of the basin of coarse sediment whose protolith appears to be the Chengde County allochthon.

现今承德向形盆地主要是由于向北冲断的承德县冲断层下盘变形的结果，主要是(1)它向北发生倒转；(2)盆地南部的粗碎屑沉积的物源主要是来源于承德县的异地体。

B Through theoretical and experimental studies, the paper investigats the relationships between hammer geometer and stress waveform generated by the hammer. After the mechanical meanings of linear model used by others are demonstrated, a simple expression of rigidity of an equivalent spring for direct impact between a hammer and a rod is obtained. Based on the above work, a mathematical model and numerical method for the impact of the hammer with progressively changing cross-section on the rod are presented.
