Because of the condition of 〓 for two neighbour parametricspline surfaces is too strong,here,instead of it,some simple and practicableconditions of 〓 resulted from the general theorem obtained by Prof.LiuDing Yuan in Chapter 1 were proved,and three 〓 triangular splinesurfaces schemes wre presented:one is piecewise cubic spline surface patcheshaving local 〓 and whole 〓 continuity based on the refined HCTtriangulation,another is the same degree spline surface patches but based onthe refined Powell-Sabin triangulation,the third is piecewise quartic splinesurface patches having local 〓 and whole 〓 continuity based on therefined P-S triangulation.

由于对参数曲面，一阶导数连续的要求较强，我们采用第一章从刘鼎元定理导出的简单实用的几何连续条件，讨论了基于HCT加细三角剖分和P-S加细三角剖分上的两种局部达一阶导数连续而整体有一阶几何连续的分片三次样条曲面构造算法，一种局部达二阶导数连续整体有一阶几何连续的分片四次样条曲面构造方法。

To reduce the data size of CAD product model, we presented an algorithm to compress the B-spline curves and surfaces based on second-order prediction in local coordinate system.

B样条曲线曲面密集控制点是造成CAD模型数据量庞大的因素之一，对其进行压缩编码，能有效减少CAD模型数据量。

Lucretius, a Roman Epicurean, says you can think of simulacra as "images of things, a sort of outer skin perpetually peeled off the surfaces of objects and flying about this way and that through the air."

按照卢克来修这位罗马的伊壁鸠鲁主义者的说法，你可以把一个simulacra想成是"事物的图像，某种从对象的表面上永久性地剥离下来的一层外皮，然后就从空中这么飞过来"。

METHODS: Glass ionomer cement was filled into the cavity. The filling surfaces were respectively coated with vaseline, cocoa butter and luminous paint in each group. The control group was left intact.
