摘　　要：ＰＶＭ是一个基于工作站群机的分布式并行计算环境。此文以并行求解实对称三对角矩阵特征值为例，详细地阐述了应用ＰＶＭ时如何实现负载平衡、减少通讯开销，从而提高并行效率。The screen of raster scan displays consists of a number of pixels which are distributed mesh dots, so that the curves generated on it are only some approximation to the real curves and not very good looking. For example there are the problems such as the jaggies and the uneven light intensity along the curves. This paper shows that these problems can be solved in some degrees with grey-scale displays and gives algorithms to solve these problems when they are used to draw curves and make animation.
