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。

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。

The application of the alloy that can effectively reduce the release of hydrogen, the special technique in manufacturing grid, and the appropriate match of active materials of both negative plates and positive plates, all these enable spiral valve-regulated sealed lead-acid battery, greatly restrain the release of hydrogen from negative plates, at the same time the generated oxygen, due to overcharge of positive plates, arrive at negative plates through the diaphragm and compose with lead in the negative, thus enable the recombination of gas inside of the battery and prevent the case of water loss so that water addition is free.

选择特点：有较高的放电电压曲线，使用环境宽松，能完全释放能量，适用于1min以内的支撑时间，与GCplus15配合使用，可保障变频器恒定的直流电压。卷绕式阀控密封铅酸蓄电池通过采用具有极高析氢过电位的合金通过特殊工艺制造板栅，同时对正负极活性物质量的合理匹配等工艺措施，使得负极上发生的析氢过程得以最大限度地受到抑制，同时正极因过充电所产生的氧气通过隔膜到达负极，并与负极上的铅发生反应，生成水，这样便使得电池内部气体的再复合，防止失水，实现免维护。

The economy and social causes in China have procured great achievements in those twenty years. The visages of cities have experienced great changes. During the construction, the conflicts of various concepts and modes such as tradition and modern, foreign and native, civilization and blindness arise incessantly. At the same time, the fusion of different culture and concepts also occurs all the time.

中国经济和社会事业的发展在最近的20年里取得了巨大的成就，城市的面貌发生了很大的改观，在建设中，历史与现实、传统与现代、西洋与本土、文明与愚昧，各种观念与样式的冲突此起彼伏，同时，文化与观念的融合也在不断地发生。
