The main differences in sod exist in two stages - 6 - from darkly - pigmented eye to hatching , which showed two more bands ( sodl " and sod2 " ) in the isozyme pattern of embryo activated by heterogeneous sperm than that activated by homogenous sperm . meanwhile , the other two isozymes ( est and me ) detected in this paper did not show apparent differences between the embryo activated by homogenous sperm and that activated by heterogeneous sperm 对异精激发彭泽鲫雌核发育子代及其母本彭泽鲫和父本海鲤的血清、肌肉蛋白以及心、肝、肾、脑、眼等组织的酯酶( est ) 、苹果酸脱氢酶( mdh ) 、苹果酸酶( me ) 、超氧化物歧化酶( sod )和乳酸脱氢酶( ldh )电泳图谱的比较研究。
The space distribution of pigment gland density on eleven places was analyzed by allotetraploid of ( g . arboreum g . bickii ) and varieties with pigment gland of g . hirsutum g . barbadense and the progeny population which is crossed by allotetraploid of ( g . arboreum g . bickii ) g . hirsutum and ( g . arboreum g . bickii ) g . barbadense 摘要利用（亚洲棉比克氏棉）异源四倍体和陆地棉、海岛棉有色素腺体品种以及由（亚洲棉比克氏棉）异源四倍体为母本，以陆地棉和海岛棉有色素腺体品种为父本，组配成的杂交后代群体，对植株上十一个部位色素腺体密度在群体内的分布进行了初步分析。
In consideration of the defects of conventional ga , an improved ga has been investigated in this paper . the evolution speed and quality of the population are directly influenced by the change of the number of chromosomes in ga and by whether the paternal excellent information is passed to the offspring as much as it can . in regard to the questions existing in ga , an algorithm with dynamic population scale is provided in this paper 在对模拟电荷配置的程序化实现方面，本文采用智能优化方法? ?遗传算法( ga ) ，不过本文针对传统ga - csm中遗传算法的定种群规模遗传使得父本染色体的多样性受到限制及同代非同父本进行繁殖、交叉、突变的遗传方法可能收敛于局部极小值而得不到全局最优解的问题，对其加以改进，提出了一种新方法? ?变种群规模的遗传算法。
To hybrid minghui 63 of strong restore ability and high combining ability as female parent and yunnan soft rice dianlong 201 as male parent , the scent soft rice restore wenhu 206 with qing scent , strong restore ability , high combining abulity , disease resistance and high adaptability is selected according to the method of high quality and high quality combining , scent and scent combining , the crosses between wenhu 206 and scent cms line yixiang 1a , wenfu 7 , a new scent soft rice combination is selected 摘要以生产上广泛应用的恢复力强、配合力高的明恢63作母本，和云南优质软米水稻良种滇陇201作父本进行杂交，成功选育出有清香味、恢复力强、配合力高、抗病和适应性强的香型软米水稻恢复系文恢206 。
