To solve this problem, based on the concept of graph theory we give a few models and arithmetic designs of virtual backbone in the environment of different application, and propose the corresponding routing mechanism with these virtual backbones. The major achievements are outlined as follows:The state of host's power or the time of host's online plays an important role in keeping stability of a virtual backbone. With a view to this feature, the paper introduces a simple and efficient heuristic algorithm for calculating the virtual backbone by seeking a minimum connected dominating set with maximal weight. The maximality of the weight-based choice of backbone nodes guarantees that the most suitable nodes have been chosen for the role of backbone nodes so that they can properly coordinate all the other nodes and keep stability of the virtual backbone in the network.

为了解决这个问题，本文利用网络图论中的一些理论，在不同的应用环境下给出几种虚拟骨干网的模型、构建及基于稳定性和节能的算法设计，并针对这些骨干网提出相应的分层路由机制，主要研究内容和贡献如下：考虑到主机的功率大小和在线时间长短对虚拟骨干中心的相对稳固性的影响，提出用基于极大权的最小连通支配集模拟虚拟骨干网；并给出其数学模型和相应的启发式算法，确保了性能强的主机担任骨干节点；通过优化规则确保骨干网的极小性，有效地减小了控制分组转发开销；最后进行了仿真验证。

The minimality of the virtual backbone is assured by designing optimization algorithm. As a result, it can effectively decrease the overhead of control packets dissemination. Simulation resluts show the correctness and the ability of self- renew.Considering the characteristic of fast-moving in wireless ad hoc networks, we construct a virtual backbone with a independent dominating set. This method can avoid sustaining connectivity between backbone nodes and the bakebone network can be rapidly reconstructed as topology change.

对规模较大、移动较频繁的ad hoc网络，用独立支配集构建虚拟骨干网，克服了骨干节点之间必须维护连通性的问题，使得拓扑变化较快时骨干网的重构能快速实现；采用动态按需路由机制，解决了骨干节点要维护路由表的问题；还利用极大独立集的求解得到极小独立支配集；并通过仿真测试了算法的正确性及自恢复能力。

A series of novel chiral aminophosphine ligands with binaphthyl backbone and partially reduced binaphthyl backbone were synthesized from optically pure NOBIN and H〓-NOBIN respectively. The effects of binaphthyl backbone and substitutes at the phosphorous atom on Pd (0)-catalyzed allylation of racemic 1, 3-dipheylprop-2-en-1-yl acetate with dimethyl malonate were systematically investigated.

从NOBIN出发合成了一系列膦上含有不同取代基的氮膦配体MAPs以及含有被部分还原的联萘骨架的氮膦配体H〓-MAPs，将此两类配体运用于钯催化的乙酸1，3-二苯基烯丙基酯与丙二酸二甲酯的反应中，考查了膦上取代基和配体骨架对反应的影响。
