For a respectable firm to join this club costs about $2m -$1.5m for the electron beam lithographer and ancilliary equipment, plus a year's salary for about five professionals to get it all going typically a physicist to deal with the ion beams, a chemist to deal with packaging, two computer people to write software, and a

为参加这次俱乐部一个体面的坚定费用约二百万至一百五十万元的电子束lithographer和辅助设备另加一年的薪水约五个专业获得这一切会(典型物理学家处理离子束、化验处理包装，两个人写计算机软件、芯片和人来说，整个行动)。

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。
