The quaternary structures of aves, teleost and mammal Hbs were compared showing that the subunit distances and molecular volumes of aves and teleost Hbs are larger than mammal Hbs. Analysis indicates it is due to that the former two select residues with larger side chain.

通过对鸟类、硬骨鱼类和哺乳类血红蛋白的四级结构的比较，发现鸟类和硬骨鱼类血红蛋白亚基间的距离和分子体积大于哺乳类血红蛋白，分析表明这是由于前二者选择了较大侧链的残基。

Supply chain management came from classical logistic problems. With the trend of global economic developing coming into being, enterprise management is not limited to logistic and financing management. The relation of enterprises is materialized to communicate information in broad sense, and achieve cooperation and win-win results. But many contradiction produced, coordination is needed. This brought up a tideway of research in academe.

供应链管理最早从物流管理演变而来，随着全球化经济发展的大趋势形成，企业管理已经不仅在于物流和资金流，企业关系管理更多体现在广义上的信息沟通，进而达到企业间的大范围、深层次合作与共赢，其间产生的各种矛盾与协调问题困扰着企业界，也引发了学术界的研究热潮。

The performance of LEO/MEO mobile satellite communication networks with intersatellite links is analyzed in chapter 6 based on the mean message traversal.

通过增加网络中节点间星际链路的数目可以改善网络的性能，而且这种改善对采用分组交换的系统比采用电路交换的系统大。

Digital simulation for the integrated imformation transmission network of a certain power company is performed, the QoS under three configuration schemes, i.e., without QoS configuraiton, with simple differnece service configuraiton and with MPLS network configuration, are compared. Comparison resutls show that the configuration scheme of MPLS network can implement the load balance among link circuits and possesses fault self-recovery mechanism, so the failure elements can be quickly detected and the switching over of data flow among label switched paths can be realized. The fault recovery time is within miliseconds, therefore the QoS of power system realtime information can be ensured effectively and the QoS of various non-realtime information can be considered as well.

对某电力公司信息综合传输网络进行了数字仿真，比较了无服务质量配置、单纯差分服务配置和MPLS网络配置3种方案下的服务质量，结果表明：MPLS网络配置方案能够实现链路间的负载均衡，具有自愈性故障恢复机制，可以快速检测到失效元件并在多条标签交换路径之间实现数据流量的切换，故障恢复时间在毫秒级，可以有效保证电力系统实时信息的服务质量，并可同时兼顾各种非实时信息的服务质量。

The mechanical properties of the modified material were tested, and the thermal stability of the modified EP blend was also investigated by TG. The results indicate that the graft copolymerization between PU and EP effectly inforces the miscibility of the PU/EP system. Compared with the properties of pure EP, the impact strength and tensile strength of the PU/EP with high thermal stability are markedly enhanced, and the fracture surface of the PU/EP system displays tough fracture features.

研究结果表明：PU和EP分子链之间存在着化学接枝反应，能有效地改善PU/EP体系中PU和EP分子间的相容性及相互贯穿；与TDE-85与E-51的混和环氧树脂比，PU改性TDE-85与E-51的混和环氧树脂仍然具有很强的耐热性能，并且冲击强度、拉伸强度均获得显著提高；PU/EP体系断口裂纹呈明显的韧性断裂特征，说明TDE-85与E-51的混和环氧树脂PU改性增韧效果明显。

For the case of pH-induced micellization, as pH of the solutions decreases to below 4.6, micellar structure having insoluble complexes of PAA/PNiPAAm as the core and solvated HEC chains as the shell can be obtained due to hydrogen-bonding complexation between the proton-acceptors in PNiPAAm and the proton-donors in PAA.

首先发现pH诱导胶束形成的临界pH值在4.6附近，证实了胶束化机理是由于低pH下PAA接枝链上的质子给体与PNiPAAm支链上的质子受体间的氢键络合形成胶束的&核&，HEC不参与络合形成胶束的&壳&。
