In this paper, we also discuss the theory of the parallel simplex method. Undej the 2-dimensional space case, we present that simplex seriary have some properties, but we adopt some repairing measures. We proof the convergence of the parallel algorithm. At last, We give some numerical examples to indicate that the new idea is sometimes useful and helpful.

本文也对算法做了一些理论分析，主要在二维情形下，讨论了算法形成的单纯形序列本身所具有的性质，并对其做了相应的补救措施，对算法的收敛性给予了证明，最后做了一些数值实验，由于软硬件条件的限制，并行算法未能在并行计算机上实现，鉴于这种情况，我们所做的数值实验均是在串行机上完成的。

Model, then calculated the tidal consistent constant and saved as map layer as the data for tidal fast prediction. The result of comparing the model result and investigative data indicated its rationality.Later applied the model in the numerical predication of sinkable chemicals spilled beside ZhuHai region.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
