Lawrence martyr , 10 august : the monthly recurrence known as the new moon with the old moon in her arms : the posited influence of celestial on human bodies : the appearance of a star 1st magnitude of exceeding brilliancy dominating by night and day a new luminous sun generated by the collision and amalgamation in incandescence of two nonluminous exsuns about the period of the birth of william shakespeare over delta in the recumbent neversetting constellation of cassiopeia and of a star 2nd magnitude of similar origin but lesser brilliancy which had appeared in and disappeared from the constellation of the corona septentrionalis about the period of the birth of leopold bloom and of other stars of presumably similar origin which had effectively or presumably appeared in and disappeared from the constellation of andromeda about the period of the birth of stephen dedalus , and in and from the constellation of auriga some years after the birth and death of rudolph bloom , junior , and in and from other constellations some years before or after the birth or death of other persons : the attendant phenomena of eclipses , solar and lunar , from immersion to emersion , abatement of wind , transit of shadow , taciturnity of winged creatures , emergence of nocturnal or crepuscular animals , persistence of infernal light , obscurity of terrestrial waters , pallor of human beings

Pyronine B adheres to on the surface of CdS and prevents CdS aggregating, which leads to the decrease of fluorescence quantum yield of CdS. Fluorescence resonance energy transfer happens from CdS to Rhodamine B, Butyl rhodamine B and Rhodamine 6G, respectively. There is a higher FRET efficiency between CdS and Neutral red with the value being 0.282. Moreover, coupling reaction between -NH_2 of Neutral red and -COOH of CdS -TGA leads to red shift of CdS fluorescence spectrum. The reaction also occurs between Safranine T and CdS. At the same time, the Fluorescence of ST is quenched by forming ST -CdS ground state complex. Chapter 6, CdS QDs modified by chitosan and polyethyleneimine can be quenched by Cu~(2+). According to the experimental result, we develop the novel sensor for Cu~(2+).

研究结果，吡啰红与CdS之间作用形式是染料聚集在CdS的表面使得CdS不易聚集，但同时也降低了CdS的发光的量子效率；罗丹明B、罗丹明6G、丁基罗丹明B均与CdS之间存在能量转移，位阻效应使得能量转移效率最高的BRhB的相对荧光强度增大最小；中性红与CdS的能量转移效率更高，同时推测可能使CdS-TGA上的-COOH与部分NR的-NH_2发生偶联导致粒子变大而发生荧光光谱的红移；番红花红与CdS是相互荧光猝灭，可能是ST的-NH_2与CdS-TGA上的-COOH发生偶联使得纳米粒子变大以及二者形成基态复合物的共同作用的影响。

Being combining with products distribution in styrene oxidation, we propose the styrene epoxidation carry out with Ti metallacyclo intermediates, And at the same time Ti-ZSM-5 have properties both catalytic epoxidation and acid-catalysis, namely the skeletal Ti can catalyze styrene epoxidation to styrene oxide and the skeletal Ti and Al can provide Lewis acid site to cause the rearrangement of styrene oxide to phenylacetaldehyde rapidly, the solvolysis to glycols and the cleavage of C=C double bond. Ti-ZSM-5 can also provide Bronsted acid site simultaneously, which is also catalytic center for the solvolysis to glycols.

同时结合Ti-ZSM-5催化选择性氧化苯乙烯反应的产物分布结果，提出苯乙烯环氧化反应可能是通过金属有机环机理进行；Ti-ZSM-5同时具有催化环氧化和酸催化两种功能，其骨架钛可催化苯乙烯环氧化生成环氧苯乙烷，而骨架钛和骨架铝等可提供Lewis酸位使环氧苯乙烷迅速发生重排生成苯乙醛从而使其成为反应的主要产物，同时还可发生加成以及碳碳键的裂解等副反应：Ti-ZSM-5也提供Bronsted酸位，它也是生成加成产物的活性中心。

The modified surface with a high friction coefficient becomes hydrophilic.The main reason is that: there is a basic photoreaction of oxygen under UV radiation,in which atomic oxygen may highly be generated.Then the oxygen atom reacts with trace amounts of water to form hydroxyl.

其机理为：在紫外照射条件下氧气发生光化学反应形成氧原子，氧原子和微量的水发生反应形成羟基，羟基和烃发生夺氢反应形成硅烷的烃自由基，同时硅烷的烃自由基会发生β-scission裂解形成较短链的自由基。

This subset is hyporesponsive and anergic to antigen stimulation. Recently, it has been demonstrated to participate in the immune deficiency in human immunodeficiency virus infection and has close relationship with the development of acquired immunodeficiency syndrome. Meanwhile, the CD4(superscript +)D25(superscript +)Treg is also infected when the human body is invaded by HIV. The CD4(superscript +)CD25(superscript +)Treg will finally be killed by the mechanism of antibody-dependent cell-mediated cytotoxicity. Because of the decrease of the CD4(superscript +)CD25(superscript +)Treg, it can't function as a immune suppressor as a result of the excess of activation of HIV and gradually exhausting of the T cell, which shows that the CD4(superscript +)CD25(superscript +)Treg plays a inhibitory role in the different stages of the development of the HIV as well as different effects in the pathogenesis of AIDS.

它能够抑制自身免疫病的发生和发展，参与肿瘤免疫的调节，同时在感染和移植免疫中也发挥着极其重要的作用。T细胞的这一亚群具有免疫调节和免疫抑制的特性，新近发现它亦与爱滋病的发生、发展关系密切HIV进入人体后，CD4D25调节性T细胞抑制了机体的免疫效应但它也同时被感染，最终由于细胞毒的作用而死亡由于调节性T细胞数量的减少不能有效的发挥其抑制作用，HIV持续的过度活化使得T细胞逐渐耗竭说明在HIV发生、发展的不同阶段Treg细胞可能都发挥了免疫抑制作用，但是却对HIV感染与爱滋病发病的进程产生了不同的效应。

Then we introduced transition probability kernel for the hidden state process and the confederated process. In the deep research, we found that some similar parameters of state transition probability, observation symbol probability and initial state probability were involved in the transition probability kernel of the confederated process. So we can complete the training of traditional HMM parameters by training the transition probability kernel of the confederated process. To our surprised, we got the consistency of transition probability kernel of the confederated process. Meanwhile, we proved the rationality and reliability of the parameters estimation equations under the classical B-W algorithm.

然后对联合过程的转移概率核展开研究，我们根据过程的取值空间的不同，引入了隐状态空间和联合过程空间上的转移概率核，研究中发现在联合空间上的转移概率核包含了在一般的隐马氏模型的参数估计中的所有类似的三组参数(转移概率，观测概率和初始概率)，因此对传统的隐马氏模型的参数训练我们可以通过联合过程的转移概率核的训练来完成，更令我们惊奇的是联合过程的转移概率核还具有一致性；同时对于Baum提出的经典的B-W算法给出的关于模型的参数重估计公式，证明了它的合理性和可靠性，即模型经过重估计后的参数能够满足给定的单观测序列在模型下发生的概率是单调递增的。

The following main results are obtained: The TiO_2 photocatalyst with small crystallite size, high surface area, narrow and uniform pore size distribution, and microporous frameworks could be prepared out by applying MW radiation in the preparation process. The microwave-induced fluorescence technique verified for the first time that microwave enhanced the formation rate of hydroxyl radical, leading to the increase in the photocatalytic efficiency. Compared with the conventional catalyst, TiO_2 prepared by MW dielectric heating owns a higher UV absorption ability, and its optical absorption edge and photovoltaic response are shifted toward the short wavelength region, resulting in increase of photooxidation efficiency. The photocatalytic conversion and the mineralization ratio of acetaldehyde are increased respectively by 30% and 40% over the TiO2 prepared by MW radiation when compared to the TiO2 prepared by the conventional heating. For the MW-assisted photocatalytic reaction over the MW-prepared TiO2, production of hydroxyl radicals is enhanced by 22.5%, and the photocatalytic conversion is accordingly increased by 20%. Similarlly, applying MW also increased the photocatalytic conversion and the mineralization ratio of acetaldehyde over TiO2/Al2O3 sample.
