We investigated the effect of visiblelight on the UV-polymerization of diacetylene and an accelerationphenomenon of the visible-light on the monolayer polymerizationwas observed. It means that the visible-light can accelerate the chainpropagation but have no effect on the chain initiation, thus benefitthe producing diacetylene polymer with higher molecular weight.

考虑到双炔酸聚合过程中，链引发和链增长所需的激发波长不一样，前者的激发波长必须小于310 nm，而后者的激发波长在可见光区，我们因而在液面上测量了可见光对聚合反应的影响，发现可见光照的确能加快反应的进行，就是说，在链引发和链增长的竞争中，我们可以用可见光加快链增长过程，一定程度上增大分子量。

FT-IRDSC tests were taken to analyze the structure,and the terms-mechanical properties,shape recovery behaviors and tensile properties were discussed to study the extender influence on SMPU.The results show that SMPU extended by ethanediol and FA has good micro-phase separation structure and soft...

结果发现，扩链剂对SMPU有一定影响，用FA、ED扩链的SMPU具有较好的微相分离，而DE扩链的具有较好的软段结晶性能；FA、HD的SMPU具有较低的形状回复温度和较快的形状回复速率，HD、DE扩链的则具有较好形状固定性能，FA、DE扩链的SMPU循环使用性能较好；同时FA、HD的SMPU具有较高的弹性模量与力学强度。

The prepared PU was an elastic solid,which could dissolved in ethanol,and it exhibited strong deep purple fluorescence at the peak of 365 nm along with a shoulder at 386 nm as a thin film. Obviously,the prepared PU also was a kind of uncommon ultraviolet-emitting polymer materials.2.A novel water-soluble rod-coil block copolymer was designed and prepared successfully via the facile isocyanic acid polycondensation method using polyfluorene as rod segment and polyethylene glycol as coil segment in the main chain for the first time.

所制备的聚氨酯是一种弹性固体，可以溶解在乙醇中，同时又显示出具有半导体性质的荧光性能——最大荧光发射峰在365 nm并且在386 nm处有一个小的侧肩峰，可见它又是一种非常难得的紫外发光聚合物材料。2、首次采用了简单的异氰酸酯反应，成功地将聚芴作为刚性链段和聚乙二醇作为柔性链段，以嵌段方式连结到聚合物分子主链上，从而形成了一种新型的具有刚性链—柔性链结构的嵌段共聚物。

In the first, the thesis classes the information that could be shared in supply chain, stock information, demand information, sell forecast information, produce/deliver plan information and others. Then describes the flow of information in supply chain, establishes the decentralized, centralized and colligated control model of information flow. Through the analysis of indetermination, information asymmetry, bull-effect and the balance of collision target in supply chain, explains the value of information in supply chain.

论文首先对供应链中的可共享信息做出了界定，包括库存信息、需求信息、销售预测信息、生产/配送计划信息以及其它信息等；分析了供应链中的信息流，建构了信息流的分散控制、集中控制及综合协调控制三种控制模式；并通过对供应链中的不确定性与信息不对称，&牛鞭效应&的形成与产生原因以及供应链冲突目标的协调分析，说明了供应链中的信息价值。

For the first time, the dynamics changing process of KGM chain in vacuum is proposed, We obtained the following results: polymerization degree influences the stability and shapes of the chain, the chain stability drops with the increasing of polymerization degree, for the high polymerization degree KGM, KGM chain takes on irregular curl state; acetyl group is not the main factor influencing chain conformation , during the course of dynamics movement KGM chain takes on irregular curl state before and after acetyl group was doffed, Extending and curling states change periodicity and has good flexibility.

首次提出了KGM链的动态模型，得到了以下结果：聚合度影响其链形态和稳定性，对于高聚合度的魔芋葡甘聚糖来说，其链呈现无规卷曲状态且稳定性下降，在整个动态运动过程中KGM链脱乙酰基前后都呈现无规卷曲状态，而且其伸展和卷曲的变化是周期性的，表现出了很好的柔性，说明乙酰基不是影响其链形态的主要因素，二面角能和静电作用是真空中影响单链构象的主要的键合作用力和非键合作用力，但是乙酰基对氢键作用的影响(来源：ABC6c论文网www.abclunwen.com)较大。

In order to avoid bottleneck links, a new concept, the link balance weight, is defined, which is used to reflect the link usage. The larger value is given to the link with heavy load, and the less value is given to the link with light load.

在选路时为了避免瓶颈链路，本文创造性地提出了一种新的&链路均衡权值&概念，即根据链路的带宽使用情况为链路赋权值，负载重的链路赋较大的权值，负载轻的赋较小权值。

The 329 bp terminal inverted repeat sequence can't form the conserved fold-back secondary structure as that of many Streptomyces linear replicons. Lacking of typical Streptomyces tap/tpg locus for te-lomere replication, pPR2.3c encodes a protein with two domains resembling the telomere associated protein of Strepto-myces and helicase of Haemophilus respectively. No typical Streptomyces iteron-rep locus for replication from the cen-trally located origin, two DNA fragments containing almost all pPR2 were cloned and introduced by transformation into S.

其端粒末端反向重复序列的长度为329 bp，不能像多数链霉菌的线型质粒那样能形成保守的&折返&的二级结构。pPR2虽然没有参与链霉菌端粒复制的保守的tap/tpg基因，但是pPR2.3c基因编码了一个双结构域蛋白，分别同链霉菌的端粒复制相关蛋白Tap和嗜血杆菌的解旋酶具有相似性。pPR2缺少典型的链霉菌重复序列-复制基因区段，将几乎覆盖全长pPR2的两段DNA进行克隆后，不能转化变铅青链霉菌。
