摘要
介绍了双参数控制的双Ｂｅｔａ样条曲面的算法、投影变换、消隐处理，在屏幕上自动调整和显示的原理和实现方法，并给出了应用实例。
PVM is a distributed parallel computing soft environment on the basis of workstation cluster. By an example of parallelly solving the symmetric tridiagonal eigenproblem on PVM, this paper presents some special and effective strategies for maintaining load balancing and reducing communication overhead in order to improve parallel efficiency.
