High elastic etherate is applied to foam on the spot in normal temperature and normal pressure,so as to form the foam whose inner surface is the same as that of the jade craftwork and whose foaming ratio is high.The profile is cutted by laser and its surface is electrostaticly woolimplanted.

采用高回弹组合醚在常温常压下现场发泡，成型出与玉器工艺品外形吻合、发泡倍率较高的泡沫体，用激光刀剖切并对剖切面及成型轮廓面进行静电植绒，做出了外形美观、减震效果优异的高档内包装。

In order to remedy this kind of shortage, this paper presents a quick volume rendering method, for the finite element data field of dam seismic response, choices the slicing direction relying on the element surface which normal line has the smallest included angle with the view direction, slices elements to many quadrilaterals, blends the colors of these quadrilaterals by using OpenGL blending technology, and then superimposes all elements one by one.

为了弥补传统体绘制静止画面不能明确判断场值集中部位的不足，提出一种快速体绘制算法，针对大坝地震反应有限元计算数据场，根据每个单元法线与视线夹角最小的表面来选择剖切方向，将单元剖切成多个四边形面后，对单元的绘制顺序进行合理排序，利用OpenGL图形库函数进行颜色融合，再将各个单元依次叠加，从而生成了三维数据场的体绘制图。
