And the mechanism of ATRP is discussed from the view of complex-catalytic reaction. It is deduced that the active center in ATRP is not pure radical but complex active center, which maybe a complex with radical and complex ion. The structure of active center may have a "bridge"structure formed through propaganating radical and transition metal ion, and the active center exists in a"cage"generated by ligand-transition metal ion-organic halide and monomer or solvent.

论文运用基团贡献理论对一些实验现象和结果进行了讨论和分析，并结合研究结果对络合催化引发原子转移自由基聚合反应的机理进行了初步的探讨，认为：过渡金属化合物与有机配体参与的络合催化引发原子转移自由基聚合反应中，聚合反应的活性中心不是纯粹的自由基活性中心，而是与过渡金属相结合的、有着某种"笼"结构存在的复合式活性中心，同时该活性中心以自由基特性为主，同时兼具某种程度的其它活性中心特征（如阳离子和络合聚合活性中心）。

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。

The existence, development and operation of rule of law always present themselves in one given public discourse or linguistic environment, whilst rule of law in its turn needs and does engender a public discourse to support its own existence, development and operation.

法治的存在、发展与运行总是在一既定的公共话语或者语言环境之中展开的，同时它也需要并产生着支持它自身的存在、发展与运作的公共话语体系。

III.As an old dock, Shimen Dock plays an important role in the development of the surrounding areas and transportation of consumer products. It provides more than 100 employment opportunities and contributes to social satiability.

三、石门码头是存在了多年的老码头，码头的存在不仅为周边城市发展和日用物资的中转发挥了积极作用，同时码头的生产作业解决了一百多名职工的就业问题，也为社会稳定发挥了积极作用。

Equivalent stress nearby the spot weld is greater other placeand there is obvious stress concentration.

由应力分布情况得出，在焊点附近的等效应力较大，存在明显的应力集中现象，同时由于折流缝焊的存在，增加了波面传热板强度。

The author learn that the curriculum in kindergarten stray away from the real life in the way of a field research by observing in a few kindergartens and by means of analyzing text. There are some examples such as ignoring the educational values of the daily life activities; the curriculum"s divorcing from the children"s life experience and so on. At the same time, the author finds that there are some good examples for the curriculums closely relating to the real life, so we say that it is possible for the curriculum in kindergarten to come back to life.

通过对幼儿园的实地观察以及对文本的分析，笔者认为幼儿园课程存在与生活背离的现象，如忽视日常生活活动的教育价值，课程内容脱离幼儿生活经验等；同时也存在与生活紧密联系的课程范例，所以，幼儿园课程回归生活是可能的。

We also detected genomic changes which were possibly associated with the reduced fitness in backcross by amplified fragment length polymorphism. The changes mainly involved loss of parental AFLP bands (backcross1, F1 hybrid female×olive flounder male, 3.96%; backcross2, F1 hybrid female×summer flounder male, 6.03%) and gaining of novel bands (backcross1, 5.63%; backcross2, 3.28%).

同时，利用AFLP对回交子代基因组的变化进行了分析，发现回交中不仅存在亲本位点的丢失(褐牙鲆回交子代-回交1， 3.96%；夏牙鲆回交子代-回交2， 6.03%)的现象，也存在非亲位点(回交1， 5.63%；回交2， 3.28%)的现象。

With the raise of temperature, the surface charge quantity, surface potential, surface charge density decrease sharply.
