It consists of the next three aspects: firstly, we study Murthys' open problem whether the augmented matrix is a Q0-matrix for an arbitary square matrix A , provide an affirmable answer to this problem , obtain the augmented matrix of a sufficient matrix is a sufficient matrix and prove the Graves algorithm can be used to solve linear complementarity problem with bisymmetry Po-matrices; Secondly, we study Murthys' conjecture about positive semidefinite matrices and provide some sufficient conditions such that a matrix is a positive semidefinite matrix, we also study Pang's conjecture , obtain two conditions when R0-matrices and Q-matrices are equivelent and some properties about E0 ∩ Q-matrices; Lastly, we give a counterexample to prove Danao's conjecture that if A is a Po-matrix, A ∈ E' A ∈ P1* is false, point out some mistakes of Murthys in [20] , obtain when n = 2 or 3, A ∈ E' A ∈ P1*, i.e.

本文分为三个部分，主要研究了线性互补问题的几个相关的公开问题以及猜想：(1)研究了Murthy等在[2]中提出的公开问题，即对任意的矩阵A，其扩充矩阵是否为Q_0-矩阵，给出了肯定的回答，得到充分矩阵的扩充矩阵是充分矩阵，并讨论了Graves算法，证明了若A是双对称的P_0-矩阵时，LCP可由Graves算法给出；(2)研究了Murthy等在[6]中提出关于半正定矩阵的猜想，给出了半正定矩阵的一些充分条件，并研究了Pang~-猜想，得到了只R_0-矩阵与Q-矩阵的二个等价条件，以及E_0∩Q-矩阵的一些性质；(3)研究了Danao在[25]中提出的Danao猜想，即，若A为P_0-矩阵，则，我们给出了反例证明了此猜想当n≥4时不成立，指出了Murthy等在[20]中的一些错误，得到n=2，3时，即[25]中定理3.2中A∈P_0的条件可以去掉。

The 1920 saw the emergence of a new psychological school called Gestalt psychology.it was founded by a group of German psychologists such ad Max Wertheimet,Kurt Koffka,and Kurt Lewin.most of their early research was focused on the area of perception,aiming at the exploration of the relationship between parts and whole in people's petceptual experience.from their experiment,they found that people perceived objects and scenes as organized wholes beforethey noticed their component parts.For example,when people catch sight of a desk,they will recognize the desk asa whole before noticing its legs and other parts.that is why they use the word Gestalt,which means roughly"organized shape"or "whoe form" in English,to name their school of psychology

在1920年看到了一个新的心理称为塔psychology.it学校的出现，是由德国心理学家等广告最大Wertheimet，科特考夫卡和库尔特其早期研究Lewin.most成立于知觉的领域集中，瞄准之间的部分和整个人民的关系探索单曲petceptual 经验。from他们的实验中，他们发现，人们认为的对象和有组织的整体，场面beforethey发现自己的组件部分。F例如，当人们捕捉，桌上看到，他们将承认前注意到它的腿和其他parts.that桌子阿萨整体他们为什么用这个词塔，这意味着约&组织型&或&所有形式&的英文，说出他们的心理学校。
