Based on mechanism and vehicle theories theoretical analysis is pursued and normal driving conditions are put forward. The relations are analyzed between load distribution and power consumption. Mechanical formula is proposed. Furthermore in this paper the theoretical model of the total power consumption is established, and the relations of the total minimized power consumption with the air-cushion pressure and the fan revolution are discussed. The optimum operation point is put forward. The dynamic digital simulation studies are carried out on the operating procedure of the half-track air-cushion vehicle on soft terrain. Mechanical parameters and soil mechanics characteristics affecting vehicle power consumption and riding performance are analyzed. At the same time according to the model formula, the automation control problem is discussed. It is a theoretical instruction for further automation control.

Birth from" demigod " of the first prototype of the hero image at The Ancient Greece literature, This"The Hero Type of Demigod" has been controled and dominated the figures\' molding of The Western literature , The hero images in the not coetaneous literature all can be treated as the different"anamorphosis" of "The Hero Type of Demigod".

从英雄形象的第一个原型"半神"在古希腊文学中诞生，这个"半神式英雄"就一直支配并主宰着西方文学的人物塑造，不同时代的文学中的英雄形象都可以看作是"半神式英雄"的不同"变体"。

However, despite such categorical pronouncements as "…the above shows that the ring is not the fundamental system for associative algebra of double composition "found in [Vandiver,1939], semirings never became popular and the interest in them among algebraists gradually petered out, although it never died completely.

这些年来，半环被各类研究者所探究或者是在他们的本身及尝试从半群理论和环论中拓展研究方法，或者联系于各种应用。然而，尽管这种范畴的看法"…上面表明环不是最基本的系统对于双复合结合代数"（这句话出自[Vandiver ，1939]）。半环没有受到他们的欢迎和引起他们的兴趣进而逐渐淡化，尽管没有彻底的消亡。

WE WILL LEAVE Danglars struggling with the demon of hatred, and endeavoring to insinuate in the ear of the shipowner some evil suspicions against his comrade, and follow Dantès, who, after having traversed La Canebière, took the Rue de Noailles, and entering a small house, on the left of the Allées de Meillan, rapidly ascended four flights of a dark staircase, holding the baluster with one hand, while with the other he repressed the beatings of his heart, and paused before a half-open door, from which he could see the whole of a small room.

This thesis consists of two parts. The first one was that boundary value problem was discrete with five point difference method. Three kinds of memory formats were studied, which were full matrix, half band width and row compress sparse. Full matrix memory format and half band width memory format first was contrasted. The results show that half band width has efficiency in space. Then the algebraic system of finite element method was solved by Gauss-Seidel iteration method to popular row compress sparse memory format.

本论文由两部分组成，第1部分针对边值问题，用5点差分格式进行离散，并对离散矩阵这类大型稀疏矩阵，研究了系数矩阵的3种存储格式的优劣，即：满矩阵存储格式、半带宽存储格式和按行压缩稀疏存储格式，首先我们将满矩阵存储方式和半带宽存储格式进行了对比，迭代法的数值实验表明：利用半带宽存储的矩阵在空间运算方面具有高效性；然后针对目前数值实验中流行的按行压缩稀疏存储格式，实现了有限元离散代数系统的迭代法的求解。
