The parallelization of the neural network algorithms mentioned above is also discussed in this thesis.

以多光谱图象为主，探讨了图象的分割、特征提取以及大目标识别的神经网络方法，取得了较好的实验结果。

It was found that La〓 does not affect the binding affinity between calmodulin and Polistes Mastoparan, a known calmodulin binding peptide, neither the conformation of the ternary complex. Excessive amount of La〓 result in the decrease of the binding constant and the disrupted conformation. The binding affinity of La〓 to calmodulin increased in the ternary complex (La〓-CaM-Mas/Mas X), which suggested the coordination between the two global domains. The binding priority between the two global domains is also changed: La〓 more is likely to bind to the C-terminal of calmodulin than to N-terminal, thus facilitates the binding of Mas/Mas X to the C-terminal of calmodulin as the first step of the Mas/Mas X binding.

在以钙调蛋白结合肽—Polistes Mastoparan和Mastoparan X为对象的研究中，我们发现，除非过量，否则La〓的存在不影响钙调蛋白与Mas间的结合常数以及构象；过量的La〓（La〓/CaM摩尔比＞4）将引起钙调蛋白结合功能的下降，同时明显改变金属-钙调蛋白-Mas三元复合物的构象；La〓对Ca〓CaM-Mas的N末端表现高度选择性，显示了在三元复合物中两种离子间的协同效应；在三元体系中，La〓与钙调蛋白的亲和力明显上升，而且亲和力上升的程度因钙调蛋白结合肽的不同而有明显差异，显示了作用的选择性；Mas和MasX的存在改变了La〓在钙调蛋白上的结合顺序，La〓很可能优先与C末端结合，从而使Mas/Mas X首先与C末端结合，该顺序与钙离子相同；La〓的参与使三元复合物在动力学上更加稳定。

Founder of American practicalism and semiotics, C.S Pierce identifies three categories of signs: icon, index and symbol.

美国现实主义和符号学的创立者皮尔斯，把符号分了三种：象似符号、标记符号和象征符号，他认为能指和所指之间所存在的自然关系叫做象似性。

The skull did not surprise Stephen very much---he had already noticed one rolling about among the coconut bailers and he knew thay had no great significance in the South Seas---but it was with real concern that he saw and after a moment recognized the little wizened purselike objects pinned to the slab, as vermin might be to a European gamekeeper's door.

骷髅并没有让斯蒂芬吃惊---他早已看见，在那些椰子壳做的戽斗中就滚着一个，而且他知道骷髅在南海并没有什么特别的意义---但他看见了钉在木头上的一样东西，它小小的象钱包一样，干瘪缩皱，就象欧洲的猎场看守人门口挂的害兽，等他片刻之后认出了那个东西，他才真正担心了。

When a strong electron-withdrawing group (e.g., nitrobenzene group) is located on the position 3, the twisted configuration between pyrazoline ring and the substituted phenyl group on the position 3 is the fluorescence emission configuration of this kind of 2-pyrazolines, and the planar configuration between two moieties is also the best non-radiative decay configuration of these compounds.

对于C3位取代基为强的拉电子基团的化合物，C3位取代基与吡唑啉环相扭曲的构象是化合物分子的发光构象，而两者处于同一平面的构象是化合物的最佳非辐射衰变构象，与N1所联取代基的旋转扭曲无关。

It can be proposed that when the substituent is an electron donor, the twisted configuration between pyrazoline ring and the moiety attached on N1 is the fluorescence-emitted configuration of 2-pyrazoline, and the configuration where two moieties are placed in a co-plane is the best non-radiative decay configuration of these compounds.

这表明，对于C3位取代基为推电子基或弱的拉电子基团的化合物，N1所联取代基与吡唑啉环相扭曲的构象是化合物的发光构象，两者处于同一平面的构象是化合物的最佳非辐射衰变构象，与C3所联取代基的旋转扭曲无关。

From the photophysical behaviors of 1, 3, 4-triaryl-2pyrazoline compound (TPP16) at low temperature, it can be considered that the twisted configuration between pyrazoline ring and the non-substituted phenyl group on the position 1 is the fluorescence configuration of conjugated system Ⅰ, and the twisted configuration between pyrazoline ring and P-nitrobenzene group is fluorescence configuration of conjugated system Ⅱ.

研究了1，3，4-三芳基-2-吡唑啉化合物TPP16在低温时的发光情况，发现：在低温77K下，共轭体系Ⅰ(苯基-N1-N2＝C3-苯基)在非极性溶剂中不发荧光，在极性溶剂中有较强荧光发射；而共轭体系Ⅱ(N1-N2＝C3-C4＝对硝基苄叉)在非极性溶剂或极性溶剂中均有荧光发射，表明N1所联取代基与吡唑啉环相扭曲的构象是共轭体系Ⅰ的发光构象，而对硝基苄叉与吡唑啉环相扭曲的构象是共轭体系Ⅱ的发光构象。

Thank you for all your support since we started. I know it looks wired and pitty to let go all rebill like faxxaff mention but I think about this clearly.

谢谢你们所有人的支持自从我建站以来，我知道就象faxxaff提到，放弃现在的一切重新来过，就象脑壳锈斗了，但是我已考虑的很清楚了。

An image forming device includes an electrostatic latent image carrier on which an electrostatic latent image is formed, a main frame which supports the electrostatic latent image carrier, and a developing unit which is inserted removably in the main frame.

一种成像设备，包括：一个静电潜象形成在上面的静电潜象载体、一个支撑该静电潜象载体的主框架以及一个可拆卸地插入到该主框架上的显影单元。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
