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。

Pepys in the realization of their ideal simple process of gradual loss of self, money, fame or so of his consciousness, when you see Joe, he always felt Joe's behavior behavior is not appropriate for the identity he now felt ashamed, when the truth is white, when Pepys found himself in ignorance.

匹普在实现自己的理想过程当中渐渐的失去朴实的自我，金钱、名誉左右了他的意识，当看到乔时他总是觉得乔的举止行为不适合他现在的身份而感到羞愧，当真相大白时匹普发现自己的愚昧。

When we in the tree-lined walk through the campus, we will feel relaxed and happy

当我们在绿树成荫的校园中漫步时，一定会感到心旷神怡；当我们在窗明几净的教室中读书时，哪能不全神贯注？

Many thousands of investment-company boards meet annually to carry out the vital job of selecting who will manage the savings of the millions of owners they represent. Year after year the directors of Fund A select manager A, Fund B directors select manager B,etc.… in a zombie-like process that makes a mockery of stewardship. Very occasionally, a board will revolt. But for the most part, a monkey will type out a Shakespeare play before an "independent" mutual-fund director will suggest that his fund look at other managers, even if the incumbent manager has persistently delivered substandard performance. When they are handling their own money, of course, directors will look to alternative advisors – but it never enters their minds to do so when they are acting as fiduciaries for others.

成千上万的投资公司董事会每年都会聚会行使投资人赋予他们的重大责任-为其背后所代表的数百万投资人选择适当的人选来管理其身家财产，只是我们发现，年复一年董事会只不过是装出掌握控制权的表面假象，A基金公司永远选择A经理人、B基金公司也总是选择B经理人，其制式程序就像僵尸般食古不化，当然偶尔也会有董事会突锤，但大部分的时候，就算现任的基金经理人的表现有多差劲也一样视而不见，我想要等这些独立行使职务的董事愿意开始建议寻找其它合适的经理人人选，恐怕连猴子都有办法写出莎士比亚歌剧了，吊诡的是，当这些人在处理自己的资产时，只要发现苗头不对，他们肯定立刻见风转舵，另觅贤能，实在是无法理解当他们在受托帮他人管理资产时，为何脑筋偏偏就转不过来呢？

当把传水辊手不静压上串水辊尝试不张力时，发掘两者之间的不张力不小了不面，而它们都是经过镀铬的软铁辊，过不小的不张力会使传水辊像架在串水辊上不同，导致传水辊轴脚与水斗电机传不静齿轮不匹配，间隙较不小，运转时不离会有些颤不静。

When birding, I like my binoculars hanging on their strap around my neck when not in my hands, but when scrambling around, hiking, or engaged in other activities, I prefer to stow the binoculars in a more secure location, ideally in their padded case affixed to my belt.

当观鸟时，如果镜子不在手上，我宁愿把它用镜绳挂在脖子上，但当攀山、远足或从事其它活动时，我宁愿把望远镜放在一个更安全的地方，那就是把镜袋穿在腰带上，然后把镜子放在镜袋中。

We are trying to find a childhood can be when we run around in the eastern hemisphere, he was walking in the Western Hemisphere; when we are circling the Antarctic when he was playing in the Arctic ...... In short, it is a total contrast with our position in the flow, we do not move, it does not move, we take a step backwards, he would step forward, in any case, it will not meet with us.

我们努力寻找着童年，可当我们在东半球乱跑时，他却在西半球漫步；当我们在南极绕圈的时候，他却在北极嬉戏……总之，它总与我们在相反位置流动，我们不动，它也不动，我们向后走一步，他就向前走一步，不管怎样，就是不与我们相见。
