| 6. | This thesis suggests a process considered minimizes the population size as similar individuals occur in the fitter members of the population , which helps reduce the execution times for ga by removing the redundancy associated with the saturation effect found in the later generation . this thesis uses a method that adds dynamic penalty terms to the fitness function according to the optimal degree of solutions , so as to create a gradient toward a feasible suboptimal or even optimal solutions . on the basis of the difference of the biggest and the smallest of fitness of individual , modifying the fitness function in order to convergence is a satisfaction 动态调节种群大小,去掉遗传算法在迭代后期搜索产生的过多相似个体,达到减少计算时间的目的;按照解的优劣程度给适应度函数增加一个在ga搜索过程中动态改变的可变罚函数,给搜索最优解创造一个梯度,使遗传算法收敛到可行的较优解或最优解;根据适应度值最大和最小个体的差修正适应度函数,使适应度函数值适中不容易造成收敛太快、局部收敛或根本不收敛而变成随机搜索;为了避免“近亲繁殖”采用竞争择优的交叉操作;利用并行遗传算法的思想,提出一种自适应多子种群进化策略;提出人口汰新政策来解决类似甚至相同的个体的情况发生。 |

| 8. | The power angle characteristics are acquired and compared with the unsaturated curves . it is concluded that the stability limit of the power angle is less than 90 degree . reactive power regulating curves are calculated and compared with those curves when saturation effect is not considered , the result is that u type curves are deviated to the right 通过对同步发电机各种运行曲线的计算,在已有文献的基础上更进一步分析了铁磁材料饱和以及磁场畸变对同步发电机运行特性和参数的影响;求出了空载特性曲线和零功率负载特性曲线,在不同的电枢电流下计算得到的波梯电抗不同;求出了功角特性曲线,与不计饱和时的功角特性曲线相比较,功角稳定极限小于90 ;求出无功调节曲线,与不计饱和时相比较, u型曲线向右偏移。 |
| 9. | The results show that ( 1 ) loops are in general more variable than stems , and in loops a strong adenine bias are observed : ( 2 ) there does not exist a saturation effect in stems , loops or all positions of the 16s rrna gene fragments : ( 3 ) in the molecular cladogram , bagarius forms a sister group with glyptothorax , and euchiloganis forms a sister group with pareuchiloglanis , and exostoma forms a sister group with glyptosternum : ( 4 ) the phlogenetic positions of pseudecheneis , exostoma and glyptosternum are not recognized ; the glyptosternoid fishes are not monophyly although they are defined by 13 osteological apomorphies ; the incongruence of cladograms between molecular and morphological sets may be caused by less informative sites of the 550 homologous sites ; ( 5 ) e . davidi and e . kishinouyei could be the same species according to the genetic distances ; p . sinensis and p . anteanalis could be too 结果表明: ( 1 )环区平均变异位点较茎区多,有很强的a偏好性; ( 2 )没有替代饱和现象; ( 3 )分子系统树上?属和纹胸?属构成姐妹群,石爬?属和?属构成姐妹群, ?属和原?属构成姐妹群; ( 4 ) ?属、原?属和褶?属的系统发育位置不定, ? ?鱼类并未形成一个单系类群;可能的原因是所得到的16srrna基因片段信息位点太少; ( 5 )青石爬?和黄石爬?可能是同一物种,中华?和前臀?可能是同一物种。 |
