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。

Based on the above results of macro expansion and microstructure studies, the limitation of the early ASR expansion mechanism has been noted, and the new ASR models for aggregates with various texture and structure have been put forward. The early expansion mechanism was suitable for interpreting the behavior of the high reactive aggregate with only one constituent.
