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。

For instance, the sunglasses at their beach tryst will recur when Humbert first sees Lolita; the appearance of Annabel's mother during their garden tryst will bear relevance to Lolita's mother; and even Humbert's phrase "haze of stars" suggests some cosmic connection to Lolita, whose last name is Haze.

海滩上幽会时出现的墨镜当Humbert看见洛丽塔时也会再次出现;在花园里幽会时,Annabel的母亲和洛丽塔的母亲有关联;甚至Humbert的话:"haze of stars"也暗示了和洛丽塔有宇宙联系--洛丽塔的姓是Haze。

The quaternary GalnAsSb can be used for the bolometer, IR radar, monitoring of the environment, trace gases and other interesting purpose for its special response wavelength. GalnAsSb infrared detectors are novel compound detectors with advantages of fast response, high sensitivity, high stability, low price, especially its character to work at room temperature.

当其晶格参数与InP衬底的晶格参数相匹配时,其覆盖波长基本不变(1.6~1.7μm):但是匹配于InAs衬底时,覆盖波长从1.7μm变到3.4μm;而与GaSb衬底晶格匹配时AlGaAsSb、GaInAsSb四元系化合物材料可以覆盖从1.7μm至4.3μm的波段,所以GaInAsSb四元系化合物材料在红外成像、红外技术方面有重要的实用价值,同时在未来的超低损耗光纤通信中也具有潜在的应用。

The results show that there are little difference of CO sensitivity between precipitation transformation method and sol-gel method, the sensitivity of copper oxide loading on zirconium oxide or cerium oxide is better than that of loading on alumina or silicon dioxide, the optimal calcinations temperature is 500 Celsius degree and the optimal copper content loading on cerium oxide is twelve percent.

实验结果表明,材料的制备方法对气敏性质的影响不大;锆铈基氧化物的气敏性质较高,而Al2O3,SiO2作载体时效果要差一些;焙烧温度在500℃时对CO具有最好的灵敏度;当负载在氧化铈载体上的氧化铜含量为12%时,对CO的气敏性质最高。

He explained that this name was part of the title of a silly fairy tale, called The Three Princes of Serendip: as their highnesses traveled, they were always making discoveries, by accidents and sagacity, of things which they were not in quest of ... One of the most remarkable instances of this accidental sagacity (for you must observe that no discovery of a thing you are looking for, comes under this description) was of my Lord Shaftsbury , who happening to dine at Lord Chancellor Clarendon's , found out the marriage of the Duke of York and Mrs. Hyde , by the respect with which her mother treated her at table.

他解释说这个名字是"一个朴素的神话故事,称作 The Three Princes of Serendip的童话"的名字的一部分:当这些殿下旅行时,他们总是通过意外和精明地发现他们并没有寻求的东西…这种 accidental sagacity的最著名的实例你必须注意到根据这种描述你没有发现你正在寻找的东西)是我的沙夫茨伯里老爷,偶然在钱塞勒·克拉伦登老爷处用餐时,发现了约克的杜克同海德夫人的婚事是根据她的母亲在吃饭款待她时发现的。

When the sodium lauryl sulfate and p-octyl polyethylene glycol phenyl ether is used and its level in 3% and 6: 4 ratio, the polymerization process has the lowest coagulum and the highest monomer conversion. Higher reaction temperature and more level hydroxyl value lead to more coagulum, the latter also lead to larger particle size. The acid value has larger influence on viscosity and coagulum, there exist a best range. The emulsion particle size is larger for its hydrophilicity, most of its particles are connected together.

在含较高亲水单体的乳液聚合体系中,难以制得稳定的预乳化液,不能采用工业生产中常用的预乳化工艺,而只能采用混合单体直接滴加的方法;由于单体混合物的亲水亲油值较高,用阴离子型乳化剂十二烷基硫酸钠和非离子型乳化剂聚乙二醇辛基苯基醚混合,用量为单体总量的3%,且比例在6:4时,乳液聚合时具有最低的凝聚物含量和最高的单体转化率;乳液聚合反应温度升高,可以提高单体转化率,增加反应速度,但凝聚率相应提高;随着羟基单体含量的增加,聚合过程中凝聚率增加,聚合物乳胶粒平均直径增加;羧基单体有一个最佳的用量(2.6%),过高或过低凝聚率均提高;羧基含量对乳液的粘度有较大的影响,当羧基含量较低时,羧基含量增加,乳液粘度增加明显;含羟基乳液粒子由于含亲水基团较多,使得乳胶粒径增大,乳胶粒子大多数互相凝聚在一起,处于凝聚态。

First, from room temperature to 500oC, the shell structure is amorphous with crinkly and airtight character. The shell structure begins to change into γ-Al2O3 and α-Al2O3 at 900oC. The surface of shells shows nano-sized pores at 900oC from SEM and BET analyses. When heated to 1000oC and 1100oC, the shell forms stable α-Al2O3 structure with smooth surface. Cracks often occur at the triple grain junctions. The specific surface area and the total pore volume of the hollow spheres increase with the calcination temperature.

首先,将锻烧温度由室温提升至500℃时,球壳属非晶相皱褶状致密结构;在900℃时开始有γ-Al2O3相及些许的α-Al2O3相出现,由SEM及BET结果得知,900℃之球壳表面有许多奈米级孔洞出现;当加热至1000℃和1100℃时,球壳形成稳定相之Al2O3结构,壳层表面趋於平滑,且球壳在晶界处有微裂缝存在;由BET 结果得知,比表面积及总孔洞体积会随锻烧温度之增加,有增加之趋势。

Cupper atom is formed by means of the decomposition of CuBr into Cu;++, and then recombination of Cu;++. Consequently the recombination coefficient is bigger and the delay time of laser pulse gets longer when the working temperature is lower.

由于工作物质铜原子是通过分解CuBr成为铜离子,再由铜离子复合成铜原子,故工作温度较低时,复合系数较大,造成激光脉冲的延时时间变长,而当工作温度较高时,复合系数变小,使激光脉冲提前。

But on the downswing she then will become aware of what she is issing When she is feeling good she is capable of seeing and responding to the good things in her life.

但往下跌落时,就很在乎她错失了什么;她在心情好时,有能力反应生命中美好的事,但当她跌落时,爱的视觉就布满了乌云,而在乎她在生命中所错失的。

The principal of buffer is described as follows.At impulsing down,the piston moves down and vacates the annular space.The pressure in respiratory cavity decreases to a certain level and the traveling valve opens.At that time,the liquids enter into traveling valve and cavity and the plunger is impulsed upward to carry out the gentle transient at the sudden change.When the upward impulsing begins,the respiratory cavity is subjected to pressure and the traveling valve closes.During the gradual pressure rising,the liquids in respiratory cavity effuse from the upper ventage and the sudden change of force-summing direction of plunger is relieved relying on the resistance of ventage.

其原理大致是:下冲程时,活塞向下运动,让出环形空间的体积,呼吸腔内压力下降,下降到一定水平后,游动阀打开,此时,游动阀和小孔同时进液,使柱塞在从上死点处突然改变方向向上运动时得到缓冲,实现了柔和过渡;当上冲程开始时,呼吸腔受压,游动阀关闭,在压力逐渐上升的过程中,呼吸腔内的液体从上部的小孔流出,并依靠小孔的阻力使柱塞受力突然换向得到缓冲。
