In this paper, a path planning method based on GA is presented. Firstly, the model of the space robot is built to display the mapping of the end velocity and the joint velocity. Then the optimal algorithm based on genetic algorithm is presented to search the optimal solution which minimizes the disturbance of base attitude in the feasible solution space. Finally, an illustrative example is used to verify the feasibility of the algorithm.

GA antagonized SMA constriction induced by myricetin. The antagonizing effect on myricetin in shock 1, 2 and 3 hours groups was more obvious than that in the other groups. CONCLUSION :At the early stage after hemorrhagic shock, the endothelium-dependent and independent vascular contractile response show a compensatory increase.

SMA血管环对杨梅黄酮的反应主要表现为：休克0、0.5、1和2 h组明显高于正常对照组，于休克2 h达最高点；休克3 h和4 h组明显低于正常对照组，运用18α-GA阻断MEGJ后，各组血管环的收缩反应性较18α-GA作用前明显下降，其中以休克1、2和3 h组下降幅度明显大于其他组。

GA-PBCA-NP produced by the two methods both had spheric and smooth outer appearance,uniform distribution,nonadherence and stability.The diameter,ebeding ratio and drug loading in GA-PBCA-NP produced by emulsification polymerization and interfacial polymerization methods were 90～600 nm and 200 nm,60.49% and 73.87%,18.15% and 22.23%,respectively.ConclusionIt is important to add dextran 70 in preparation.

结果未添加稳定剂的纳米球表面粘连团聚现象严重，难以成球；乳化聚合法制备的GA-PBCA-NP在透射电镜下观察表面圆整光滑，粒子之间不团聚，不黏连，粒径范围在90～600 nm，包封率为60.49%，载药量为18.15%；界面缩聚法制得的纳米粒表面圆整光滑，粒子之间不团聚，不黏连，粒径大小均匀，都在200 nm左右，包封率为73.87%，载药量为22.23%，两种方法制备的稳定性都较好。

The other problem in the dissertation reveals that the RBF centers and widths can be evoked by a cooperative-competitive genetic algorithm. Using the well-known credit apportionment problem and niching problem, the different fitness measures in the GA of RBF representation have been studied and the adaptive genetic operators have been given to trade off the problems because of the fitness measure problem.

另外，研究了一种基于全局搜索的遗传算法的带有不同尺度的RBF结构确定的方法，讨论了信度分配问题和小生境问题两个概念，并把两概念应用于基于GA的RBF表示的系统模型中，详细论述了在GA优化过程中，取不同评价函数测量形式，对搜索群体性能的影响，最后提出采用自适应的遗传操作算子来平衡由于评价函数所造成的抑制过度竞争出现早熟问题的方法。

That accounts forwhy Ga clusters occupy both the half unit cells of the 7×7 in thegrowth process.

初步的第一原理计算表明单个Ga原子吸附在7×7单胞的两半具有几乎相同的吸附能(差别仅为5meV)，这意味着Ga原子会随机地占据7×7单胞的任意一半成核生长，从而Ga团簇对7×7单胞不存在优先占据的特性。

Since Al〓Ga〓In〓P possesses larger valence band difference to GaAs and wider energy gap, minor carrier reverse injection from base and space charge region recombination in the emitter are effectively suppressed in Al〓Ga〓 In〓P/GaAs HBT. Under most circumstances, quasi-neutral base recombination current dominates the base current, and its ratio to collector current varies little with collector current and temperature, thus greatly stabilizes the current gain.

Al〓Ga〓〓In〓P/GaAs HBT由于异质结的△Ev较大，发射区禁带较宽，有力地抑制了基区少子反向注入流和发射区空间电荷区复合电流；在大多数情况下，基极电流以准中性基区复合电流为主，其与集电极电流的比值随集电极电流和温度的变化极小，稳定了电流增益。
