Based on the practice of garment marketing and Philip Kotlers basic marketing theory, the author divided garment marketing channel into four elements: channel member, channel level, and the number of channel member. The four elements are classifiable. After re-classifying them, the thesis relate their own characteristics, performance of channel function, and their own adaptation. Here, the adaptation mean: which element do match the specific garment product, brand and marketing condition in order to distributing garment products efficiently and effectively.

This can result in a splitting ofwavelength-dependent loss band and make the codirectional mode coupling condition (of the fundamental core mode into cladding modes) be different at two principal input polarizations.In a PM-LPG fabricated with a PMF having relatively small birefringence , the adjacent resonant dips (slow-axis and fast-axis resonant dips) resulting from the two principal input polarizations have identical cladding mode order and the wavelength separation between them is several nanometers
这可能导致分裂的ofwavelength-dependent损失,使codirectional乐队的耦合条件(模式基本核心人才培养模式为层模式)是不同的两种主要的输入波在PM-LPG捏造和具体情况有相对较小的双折射,相邻的谐振(slow-axis和fast-axis引起共振蘸)的两种主要模式有相同的输入波的波长层顺序和他们之间的分离是几奈米的图案

As a kind of political tool of conciliating class contradiction, the early form of it emerged in Germany. Thereafter, it became a basic economic measure for anti-crisis and adjustment of aggregate demand when the modern social security system was established in the United States.
它最早出现于德国俾斯麦时期,是作为调和阶级矛盾的政治工具应运而生的;其后,以美国《社会保障法》为标志的现代社会保障制度的建立,把它作为了反危机和调节需求的基本经济手段;新中国成立之后在我国建立的社会保障制度则是作为一种赋予劳动力的权利而被制度化的……但不管怎样,在社会化大生产的条件下,社会保障制度作为社会发展的支持体系,其所具有的保护及化险功能已为全世界所认同。

The molar ratio of sulfate ions to carboxylate ions is determined by conductometric titration method and the molecular weight is tested by high performance gel permeation chromatography. The precision of these two methods is also studied. To improve the detection sensitivity, guanidine hydrochloride is used as the best derivation reagent of 911. A systematic research is done on the optimum derivatization condition of 911 and Guanidine hydrochloride. The M /G ratio of 911 has direct relation to its biological activity.
论文首先对911的基本理化性质进行了系统的分析,以电导滴定法和高效凝胶渗透色谱法分别测定了分子中硫酸根羧酸根的比值和911的分子量,并探讨了两种分析方法的精密度。911分子没有紫外吸收,为提高检测灵敏度,本文采用荧光标记法,通过对三种荧光试剂与几种寡糖和多糖衍生效果的综合比较,最终确定了盐酸胍为最佳衍生试剂,并以911为代表详细探讨了衍生化反应的最优条件。911糖链结构与褐藻胶主链结构类似,以甘露糖醛酸和古罗糖醛酸的嵌段形式存在,分子中M/G比值与911的物理化学性质和生物活性有直接关系。

Cultural theory is relative to econdric thary while intellectual cilivization construction is relative to materical cilivization construction, So cultural construction theory derives from intellectual cilivization. We can summarize Deng Xaoping's cultural construction theory in 4 aspects. First, soicalist essential charactedstic is that economic and cilivization prosper together. Second, intellectual cilivization construction is the clementary content of socialist cultual construction.
这个世纪伟人在给我们勾画现代化建设的宏伟蓝图时,始终告诫我们必须对社会主义的经济、政治和文化三者在整个社会历史进程中的互为因果、互为条件、相互促进、协调发展的关系有一个清醒的认识和把握,并由此进一步阐述了社会主义文化建设的基本内容、根本任务和建设手段等问题,成为党在改革开放历史时期领导社会主义文化建设的指导思想。

Species richness and Pielou evenness index were used to measure species diversity. Species richness in polluted area was 32-67, while in control area it was 47-82. Pielou evenness index of tree layer was 0.1161-0.8509, while those of shrub layer and herb layer were 0.1763-0.3249 and 0.0443-0.2601, respectively. The results showed that both species richness and Pielou evenness index were influenced by the point source pollution. Species importance values showed significant differences between polluted area and control area. Dominance of different species had changed, and some species even disappeared under the pressure of pollution, indicating a process of species replacement in plant communities. Such species replacement can provide a scientific basis for species selection for restoration of human-damaged ecosystem. The natural regeneration of Quercus variabilis was insensitive to pollution, while Cupressus funebris was effected seriously.
仅在污染区中出现的物种数量远低于仅在对照区中出现的物种数量;(2)可分出4种基本的群落类型:马尾松林、柏木林、栓皮栎林和马尾松+栓皮栎林,各群落特定层次的物种丰富度指数以及Pielou均匀度指数在污染区与对照区之间存在显著差异;(3)污染胁迫下,物种在群落中的生态优势度发生了变化,反映了群落中不同物种相互替代的过程,这种物种的替代可为今后受损生态系统人为恢复过程中物种的筛选提供一定的理论参考;(4)对群落中王要物种更新的调查发现:栓皮栎林对污染不敏感;柏木林污染区与对照区幼苗数量及分布格局均有明显差异,污染条件下群落未来演替受到严重干扰。
