It is related to the variational inequality problem, bilinear programming, nonlinear equation. So there is actual meaning and theories value to study how to solve it.In recent years, many algorithms for solving the generalized linear complementarity problem are put forward. But they basically belong to the traditional iterative methods, and may not be efficient since the computing time required for a solution is greatly dependent on the dimension, structure of the problem and the complexity of the algorithm used. Different from the traditional algorithms, the neural network has many advantages on calculations and real-time applications for its inherent massive parallelism and electric circuit implementation.

近年来，人们对广义线性互补问题提出了许多算法，但这些方法基本上属于传统的迭代法，由于它们的计算时间极大地依赖于问题的规模、维数以及所使用的算法，因此很难满足实时并行的要求，与传统数值方法不同，由于内在的并行分布处理信息的特点及电路实现的潜能，神经网络有着许多计算上的优势和实时性的应用，自Hopfield提出著名的人工神经网络模型-Hopfield神经网络，并将其成功应用于优化问题后，用神经网络求解优化问题得到了相当深入的研究，并取得了许多重要的成果。

There are 4 reasons leading to it: firstly, stimulated by the interests, the standards of selecting the news by the journalists and editors is not measured by its social value and real meaning but only to catering to the a audiences psychological needs seeking for the bizarreness etc.

这主要有四个方面的原因：第一，由于利益的驱使，记者编辑选择新闻的标准不是其社会价值和现实意义，而仅仅为了迎合某些受众新文化报等的心理需要；其二是新闻工作者求真求实精神的缺失，在采访过程中不对事件进行深入调查，认真核实细节情况，而是道听途说、捕风捉影、主观臆测；第三是由于职业构成和行业管理制度的缺陷，新闻记者素质水平良莠不齐，缺乏高度的职业使命感和历史责任感；新文化报是坚守新闻真实性原则的监督和惩戒机制缺失，导致新闻记者职业道德底线屡屡失守，防线每每突破，假新闻层出不穷。

According to this point it has good ability to absorb neutron and resist eradiation.Because of their high hardness and strength, excellent wear and corrosion, low density, low friction coefficient good self-lubricate and high temperature properties both silicon carbide and boron carbide components have been widely used in many industries.

由于碳化硼中的B14中子缺失，它还具有较大的热中子俘获截面，具有极好的中子吸收和抗辐射性能，由于其具有耐高温，耐酸碱腐蚀，高强度，高化学稳定性，比重轻，半导体等特点而成为众多行业的首选材料。

A modefied egg function has been proposed and used in a bounding surface model. This model has potential value of applicaton since it reflects better actual situation of soil mass under loading. That is: when a stress point is still within the yield surface, the unrccovered plastic deformation would occur as stresses change, and using closed smooth function makes stress modification in the FEM much easier.

文中提出了一个改进蛋形函数，并采用这个函数建立了边界面模型，该模型由于机理上更好地反映了土体受荷时的实际情况，即当应力点在屈服面内时，随着应力状态的改变，仍然可以产生不可恢复的塑性变形，而在计算功能上由于使用了封闭光滑的边界面，不存在角点问题使有限元程序计算显得很方便，从这两个方面看，该模型具有潜在的应用价值。
