One is a large scale nonlinear programming model with equalities, the other is a more complicated NP hard and nonlinear compound 0-1 programming model. It is difficult for the existed algorithms to fulfill the demands of efficiency and size for the above problems. Two corresponding genetic algorithms are presented, in which several suitable genetic operations are constructed to make the optimization search process in the range of feasible solutions.

一个为大规模的带等式约束的非线性规划模型，另一个为更为复杂的带NP难解问题的混合非线性0-1规划，已有算法都难以满足上述两种问题的求解规模及效率的需要，我们给出了相应的遗传算法，确定了适当的遗传操作，使得问题的寻优过程始终都在可行解范围内进行，不仅提高了优化速度，而且有效地提高了优化效果。

The paper then continues to introduce the genetic algorithms in constructing coding mode that fays in with regularity of traffic and genetic operator s.

在此基础之上引入了遗传算法，针对公交智能排班问题，构造了符合行车规律的编码方式、遗传算子，并实现了程序的编码工作，最后进行了模拟实验。

The dendrograms constructed on the basis fo Neis genetic distance showed that close genetic relationships were revealed between D. wenxianensis and D. floribunda, and between D. yunnanensis and D. elegans.

应用Neis遗传距离进行UPGMA聚类分析的结果表明，文县双盾木与双盾木之间的亲缘关系较近；云南双盾木和优美双盾木之间的亲缘关系较近。

The results of POPGENE analyze indicated that it was moderate level of the genetic diversity of Dipelta, mean PPB (percentage of polymorphic bands) h and I of 4 species of Dipelta as below: D.wenxianensis.(PPB=62.02%,h=0.1850,I=0.2826); D.yunnanensis (PPB=40.31%, h=0.1238, I=0.1874); D. floribunda (PPB=36.82%, h=0.1395,I=0.2045); D. elegans (PPB=15.51%, h=0.0583,I=0.0861). Genetic diversity in D.elegans is the lowest. It is possibly caused by the endemic distribution and local ecotope.

POPGENE分析结果表明，文县双盾木的多态位点百分率平均为62.02%，Nei&s基因多样性指数平均为0.1850，Shannon&s信息指数平均为0.2826；云南双盾木的PPB平均为40.31%；h值平均为0.1238；I值平均为0.1874；双盾木两个居群的PPB平均为36.82%；h值平均为0.1395；I值平均为0.2045；优美双盾木两个居群的PPB平均为15.51%，h值平均为0.0583；I值平均为0.0861；因此，我们认为双盾木属4个种的遗传多样性适中；而优美双盾木由于分布上的地理限制，居群的生境比较孤立，其遗传多样性较低。

Since genetic relationship between green foxtail from different region and foxtail millet resisted to herbicide is different, foxtail millet, which is relatively far away from green foxtail in local region as for genetic relationship, resist to herbicide is popularized in order to decrease the ecology risks.

由于不同地区的青狗尾草和抗除草剂谷子亲缘关系不同，可以推广与当地青狗尾草亲缘关系较远的抗除草剂谷子以减少抗除草剂谷子种植后的生态负效应。

Characters of genetic diversity are followed Three allozyme loci AAT-3, PGD-1 and PGD-2 are monomorphic. The IDH-1 was silence in S.glauca but it was active in S. itlica and S. virids. Genetic diversity of green foxtail was more than that of most of other annual primary self-pollinated plant. The yellow foxtail was complex.

我国北方青狗尾草遗传多样性特征是：AAT-3、PGD在所有供试种源中均表现单态，金狗尾草与青狗尾草和谷子相比，IDH—1表现沉默，青狗尾草同其它一年生以自花授粉为主的植物相比表现更高的遗传变异性，金狗尾草表现为倍性复合体。

In other words,163 sites in crested ibis genome were detected.The bands from 23 primers showed polymorphism.Minimurn of polymorphic ratio was 0,maximum was 85.71%,and average was 48.99%.In the population which was composed by 37 individuals, most of genetic distances between two arbitrary individuals were less than 0.1.The results showed that the degree of similarity among crested ibises was high while genetic diversity in thepopulation was low accordingly.
