Firstly we introduce the concept of Rees matrix semigroups without zero i.e.

矩形群、左群都是极其重要的半群，在Mario[2]中这两种半群都已有了很好的刻画，本文后两章将给出推广了的矩形群和左群的详细刻画，全文共分三章，具体内容如下：第一章主要对推广之后Rees矩阵半群的刻画进行了描述，在这一章里先介绍了无零Rees矩阵半群的概念，它是一类矩阵半群M=MT；I，？

The process operation symbol tells us that some specific action is to betaken. The action is indicated by a statement inside the rectangle.The statement may be written in plain language, expressed algebraically, or given in some special zymology.

处理操作的符号（图4-2中的矩形框）告诉我们需要进行某些特定的操作，该操作由矩形框内的说明加以指示，该说明可以用普通语言书写，也可用代数式表示，或者以某种特殊符号体系给定。

In order to promote the performance of AOF system, two algorithms on how to efficiently design the window, one of which is based on LMS principle and the other is bifurcating of rectangle window which treats the system window as being formed from the convolution of two lower-ordered rectangle window on the left and right branch of the dichotomic tree and therewith forms multilevel decomposition via recursion, are put forward.

It was shown that, the flow pattern in the EMPT was more complex than that in traditional one, that is, in the column chamber, the short circuit flow from the outlet nozzle of the ladle was depressed by the rotating molten steel, and horizontal recurrent flow appeared in rectangular chamber, which prolonged the average staying time of the molten steel, then reduced the volume fraction of inactive area in EMPT.

结果显示，电磁净化中间包的流场比传统中间包的流场复杂：在圆形腔中，旋转运动抑制了大包水口至矩形腔的短路流，而在矩形腔中形成水平环流，从而延长钢液在中间包的平均停留时间，死区减小，电磁净化中间包的上述流场结构及传输行为对钢液中的非金属夹杂物去除非常有利。

The results of numerical analysis show that the elastic modular and the poisson ratio have no effect on two-dimensional bearing capacity, but can affect the ultimate bearing capacity of three-dimensional foundations and control the convergence and precision of finite element calculation; the earth pressure coefficient controls the geostatic stress of foundation, sequentially affects the ultimate bearing capacity of foundations and the convergence of numerical calculation. When calculating the ultimate bearing capacity of undrained saturated foundation, the complete formulation exists shear locking, and reduce formulation exists hourglassing, so the hybrid formulation is suitable to imitate the geomaterial. When the soil obeys nonrelevent flow rule, the yielding function is different from potential function, and the elastic-plastic matrix of soil is asymmetric, so the unsymmetry numerical solver and appropriate finite element mesh is required.

研究结果表明，土体弹性模量和泊松比对二维基础极限承载力没有影响，但是影响着三维矩形基础的极限承载力，控制着ABAQUS数值算法的计算精度与收敛速度；地基土压力系数控制着地基土体中的地应力平衡，从而影响着二维条形基础和三维矩形基础的极限承载力和地基破坏包络面；对于不排水饱和软黏土地基，常规的完全积分单元会造成剪力自锁现象，而减缩积分单元则存在过于柔化的现象，故采用杂交单元来模拟较合适；当土体服从非关联流动法则时，屈服函数与塑性势函数之间存在差异，从而导致土体弹塑性矩阵呈现非对称性，在有限元计算中必须采用非对称数值解法，并且合理地划分单元才能对极限承载力进行准确求解。
