Using the main result, we also obtain a simple criterion to check if a given C(superscript *)-algebra A is Abelian, that is, A is Abelian if and only for any two positive elements a, b∈A, there is a'∈A such that ab=ba'.

利用文中的主要结论，还得到了判断C-代数A是交换一个简单条件，即A是交换的当且仅当对A中的任何两个正元a，b存在a'∈A使得ab=ba'。

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。

Have a competitor that the website is us for instance, the website name that uses us makes contest price, such making that our client often makes a mistake, the website that searchs us obviously entered the website of others however, return somebody to call ask us the domain name gives changed, appeared act against one's will one lets everybody feel very do laugh business, ourselves beautiful money does keyword of him website name contest price.

比如有个网站是我们的竞争对手，就用我们的网站名称做竞价，这样使我们的客户经常搞错，明明搜索我们的网站却进入了别人的网站，还有人打电话问我们是不是域名给换了，不得已出现了一个让大家觉得很搞笑的事情，我们自己花钱做自己网站名称关键词竞价。

I would be prepared to submit to the Congress of the United States, and with every expectation of approval, any such plan that would, first, encourage world-wide investigation into the most effective peacetime uses of fissionable material, and with the certainty that they had all the material needed for the conduct of all experiments that were appropriate; second, begin to diminish the potential destructive power of the world's atomic stockpiles; third, allow all peoples of all nations to see that, in this enlightened age, the great Powers of the earth, both of the East and of the West, are interested in human aspirations first rather than in building up the armaments of war; fourth, open up a new channel for peaceful discussion and initiate at least a new approach to the many difficult problems that must be solved in both private and public conversations, if the world is to shake off the inertia imposed by fear and is to make positive progress toward peace.

我将准备好服从美国国会和每个正式批准的指望，任何计划都会，首先，鼓励全世界研究进入最多最有效的和平时期的裂变物质的使用，并用这些确实的事情，他们拥有的所有材料需要实验去操行，那是正确的；第二，开始减小世界库存的可能破坏力；第三，允许所有国家的人民观看，在这个文明时期，东西方的世界强国对人类的第一渴望非常感兴趣的，比起建立战争的军队来说；第四，为和平的讨论打开新的渠道并开始一个至少接近很多苦难问题，这必须要解决秘密的和公众的会谈，如果世界摆脱了用恐怖欺骗的惯性，那么就会获得肯定的和平进步。

In D3 gene with 5 site mutations. There exists individual variation in the COII gene, but this variation is less than that among other members of Myzomyia Series such as An. aconitus, An. jeyporiensis, etc. In addition, one haplotype different from both An. minimus A and C was found in these 3 genes studied.②The genetic distance between An. minimus A and An. minimus C is less than that among other members of Myzomyia Series. Molecular trees based on different genes and different methods show that An.

种系发生研究表明，微小按蚊复合体亲缘种A、C间的遗传距离远小于与之近缘的同系其它成员间的距离。2个分子标记3种方法构建的基因树显示，微小按蚊A、C的种系地位非常固定，不同地域来源、不同变异类型的微小按蚊始终在同一分"枝"上，与迈蚊系其它成员相比，呈现其相对稳固的单源性。

Thus the respected historian Thomas Bailey explained in 1948 that "Because the masses are notoriously short-sighted and generally cannot see danger until it is at their throats, our statesmen are forced to deceive them into an awareness of their own long-run interests," a view recently endorsed by the director of Harvard University's Center of International Affairs, Samuel Huntington, who wrote in 1981 that you may have to sell in such a way as to create the misimpression that it is the Soviet Union that you are fighting.

因此，著名的历史学家托马斯·贝利在1948年说道："由于大众的鼠目寸光已臭名昭著，往往大祸临头才有所察觉，我们的政治家被迫欺骗他们去意识到他们的长远利益受到了威胁。"这个观点在最近得到了哈佛大学国际事务中心主任塞谬尔·亨廷顿的支持，此公在1981年曾写道：（武力干涉或其他军事行动的宣传）必须要给人留下这样错误的印象——你是在和苏联斗争。

Now and then they would compliment me on being alive, but in such a way that I felt embarrassed. They made me feel that I was alive in the nineteenth century, a sort of atavistic remnant, a romantic shred, a soulful Pithecanthropus erectus. Boris especially seemed to get a great kick out of touching me; he wanted me to be alive so that he could die to his heart's content.

他们不时会因为我还活着恭维我，但是他们的恭维方式令我很窘迫，他们叫我觉得自己是一个生活在十九世纪并出现返祖现象的遗老、一条浪漫的破布、一个有情感的直立猿人。

Valery goes on to say that this is why the year 1808, when Goethe and Napoleon met in Erfurt, was such a priceless moment in world history: Coquetry was essential at such a meeting.

我和你，沃尔夫冈·冯·歌德，都具一种特别的品质——追求完美&拿破仑如是说。这也就是为什么瓦雷里认为1808年，歌德与拿破仑在埃尔富特的会见是历史上一个不可多得的时刻。&

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
