本文将对第五代第六代中国导演中的代表人物及其代表作品进行代际差异、叙事位格、叙事视角、叙事空间、文化内涵，电影市场化方向等方面的分析性比较，从而折射出这两代电影人同源但却迥异的思想体系。

In the bit-interleaved coded modulation systems with iterative decoding, a good labeling is one of the key factors that dictate the system performance. In this thesis, Extrinsic Information Transfer chart, a popular tool to analyze the convergence behavior of an iterative decoding system, is employed for the labeling design.

外来资讯转换图是一个在迭代解码系统中很好的分析解码收敛行为的工具，在位元交错调变码的解码系统中，位元对应的设计对於提升系统效能是非常重要的，藉由不同的平均位元差异数来改变讯号侦测器转换曲线的斜率，因而从中选出一个最适合外部码的位元对应方式。

A novel carbonyl transposition led by anilines'nucleophilic addition to methyl 2-keto α-D-glucopyranoside was discovered. And the mechanism of the reaction concerned to an enol rearrangment was provided through tracing the change of 〓H-NMR and 〓C-NMR of a hemiacetal intermediate which was obtained in the reaction of o-phenylene diamine with 2-keto glycoside. Both the intermediate and the converting product were identified by 〓H-NMR,〓C-NMR,〓H-〓H COSY and HMQC.

一、发现了2-位氧化α-甲基D-葡萄糖苷的芳胺亲核加成引起羰基转位的新方法，利用核磁共振氢谱及碳谱对邻苯二胺与2-位氧化α-甲基D-葡萄糖苷加成生成的稳定中间体半缩酮化合物在氘代丙酮中的变化进行跟踪，结合对转化产物的氢氢相关谱和HMQC结构确证，提出了该反应中2-位羰基通过烯醇化互变而转至3-位的机理并得到了验证。

Incidentally, on the "T human viruses," the game in this series, there are two very important information about the situation: one is the "Resident Evil generation" of the ocean found Lane "operations MembersのDiary "and the other is in Part IIレンオ(" Resident Evil II,"the actor, in English formerly known as" Leon ", in this paper, translation of the name of" Lyon ") debut of the files"ンベLove hotベチトルレのトㄧポ"(in the second generation there is a journalist, he seems to understand a number of umbrella companies and the secret police between the unknown and will be written in a report that the file).

顺便一提，关于「T病毒侵害人体」，在本系列的游戏里有两份非常重要的资料，说明了大概的状况：一份是「生化危机一代」的洋馆里所发现的「作业员の日记」，另一份则是在二代レオン篇（「生化危机二代」的男主角，英文原名为「Leon」，在本文采用翻译名称为「里昂」）登场的档案「ベン·ベルトリッチのレポㄧト」（在二代有出现一位记者，他似乎了解一些雨伞公司及警察局之间不为人知的秘密，并且将之写成了一份报告，就是这个档案）。

Brominated butyl rubber was prepared by solution method,and its microstructures were characterized by 1H-NMR. It has three main microstructures,that is the unbrominated isoprene structure,the exomethylene allylic bromide structure (structure Ⅱ) and the bromomethyl olefinic structure (structure Ⅲ).

通过溶液法制备溴化丁基橡胶，并用核磁共振对溴化丁基橡胶的微观结构进行了分析，其中存在3种主要微观结构，即未溴化的丁基橡胶结构，溴代仲位烯丙基结构及溴代伯位烯丙基结构。

The polycondensation of the benzoguanamine and pyromellitic Dianhydride was carried out under microwave irradiation, and the resulted polyamic acid was grafted with TDI-para position substitution aniline derivatives. Thus graft polymers with different electronic effect of the end group in side chain were obtained.

将微波辐射合成的苯代三聚氰胺-均苯四酸二酐体系的PAA与TDI-对位取代苯胺衍生物反应，通过改变TDI－对位取代苯胺衍生物的对位取代基来合成具有不同电子效应的侧链端基的接枝聚合物。

The results show that the brominated reaction is complete in 1.5 initial contact minutes,an...

结果表明，丁基橡胶的溴化过程只在最初的1.5min内，随着反应时间的延长及在碱性条件下反应，发生了分子结构的重排，即由溴代仲位烯丙基结构向更稳定溴代伯位烯丙基结构转移。

The crossover operation in the traditional GA operating is that choose two chromosome cross only at random also you can cross a bit, match and cross partly, cross order and cross cycle etc.

传统GA算法中的交叉操作，是随机选取两个染色体进行单点交叉(也可以多点交叉、部分匹配交叉、顺序交叉和周期交叉等等)，但是不管是采用何种交叉操作，新的子代染色体某一基因位上的值都是由两个父代染色体中相应基因位值经过一定交叉运算(直接交换或经算术运算等)所得到的，采用这种交叉算子操作使群体经过多次迭代后群体中的个体开始出现极大的相似性，因此照此下去就会出现早期收敛现象，使得算法的收敛速度非常慢甚至只能求到问题的局部最优解。

The attack causes the cleavage of P-S double bonds, then the decomposition products reacting with the surface of Fe metal lead to the formation of the anti-wear and anti-friction film largely composed of polyphosphates and sulphides.

计算表明二烷基二硫代磷酸锌的活性元素为6位和7位硫原子，其与铁发生摩擦化学反应时，最可能的断键位置是6位和7位硫原子的双键。

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。
