交配的

We propose a concept of fitness function exploiting objective of minimization of discrepancy between the extracted edge pixels and projected model wire frame edge to evaluate each individual in population.

利用此距离值的平方和为最小的目标下设计一套适应函式，以判断各模型的适应值，再经过一系列再生、交配、与突变的演化过程后，拥有最高适应值的模型即为套合结果。

Belot and Francesconi discovered that a strong social trend towards "assortative mating" means that although educated, high-achieving men are not interested in marrying a rich woman, they do like educated high-achieving women, rather than shallow girls with shiny nails.

Belot和Francesconi发现，一种主流的社会趋势：&选择性交配&意味着就算受过教育，高收入的男人也不会有兴趣去跟一个有钱的女人结婚，但是他们更喜欢受过教育的成功女性，而不是指甲闪亮的浅薄女人。

The strong FSGS and large genetic patches may induced high level of biparental inbreeding, which reduced effective outcrossing rate.

综合野生大豆遗传多样性水平、遗传结构与交配系统的研究进行分析，在制定野生大豆保护策略特别是原位保护策略时，保持种群生境一定程度的自然扰动可以打破种群内空间遗传结构或是减弱空间遗传结构，这将提高有效异交的频率，增加种群内杂合子的频率，从而维持种群内较高的遗传多样性水平，保持野生大豆的进化潜力。

Class are our set mature phase, suit of 60 class class can upgrade directly, 1-60 class is the phase that a suit shapes, 60 level ability just begin all sorts of nurturance that can say " becomes Ji Saihan ", with the suit attribute that 60 class equip, will OK freedom alters, can upgrade into tall attribute directly the suit of 80 class, in addition, marry, sit ride copulatory, pet nurturance, also will open in 60 class, if do not like the player of PK, want you not to go only border land, basically won't somebody can kill you.

我们设定60级为成熟阶段，60级级套装可直接升级，1-60级是一个套装成型的阶段，可以说&成吉思汗&的各种养成60级才刚刚开始，和60级装备的套装属性，将可以自由改动，并可直接去升级成高属性80级的套装，此外，结婚，坐骑交配，宠物养成，也将在60级开放，如果不喜欢PK的玩家，只要你不去边境，基本上不会有人能够杀你。

A slip joint consists of outside splines on one shaft and matching internal splines on the mating hollow shaft,the splines cause the two shafts to rotate together but permit the two to move endwise with each other.

支路联合组成的一个外部样条轴和匹配的内部样条的交配空心轴，造成的样条的两个轴旋转在一起，但允许两个移动endwise彼此。

Because muscles come at such cost, Dr Gaulin thinks an evolutionary fight is going on between natural selection, which conserves metabolic expenditure and promotes longevity, and sexual selection, which willingly trades both for extra mating opportunities.

肌肉的存在要付出相当代价， Gaulin博士认为自然选择的目标和性选择的目标在进化中互相冲突，自然选择倾向于保存自己，降低代谢强度，让自己活得更长；而性选择的目标是为了得到更多的交配机会，不惜以代谢强度和长寿为代价。

Second, a lot of artificial propagation experiments were performed between different gynogenetic clones to analyze whether or not genetic recombination occurs by utilizing the identified RAPD and SCAR markers. Direct molecular genetic evidence for gonochoristic reproduction was revealed in the gynogenetic silver crucian carp, and a previous hypothesis that the silver crucian carp might reproduce both gynogenetically and gonochoristically was conformed.

二是利用银鲫的克隆多样性和其种群中存在的雄性个体，设计大量的不同繁育组合，运用已鉴定的RAPD和SCAR分子标记，分析比较了不同繁育组合子代的DNA扩增情况，探讨了这些分子标记在各个交配子代中的重组分布规律。

As a result, powerful men of high status throughout human history attained very high reproductive success, leaving a large number of offspring, while countless poor men died mateless and childless.

结果，贯穿人类历史，那些有权、高社会地位的男性的繁殖成功率是非常的高，留下了一大批数目的后代，有数不清的贫穷男性却没有过交配、没有儿女。

Formation of mating pairs, nicking of the F oriT sequence, and transfer of the 5' end of a single strand of F DNA proceed as in transfer of the F plasmid. Therefore, Part of the plasmid is transferred first, Chromosomal genes are transferred next, and the rest of the plasmid is transferred last.

雌雄菌的交配、F质粒oriT处缺口的形成、以及由单链F DNA5'末端开始转移的过程都与F质粒的转移相同，因此，首先转移的是部分质粒片段，其次是染色体基因，剩余的质粒片段最后被转移。

Results:weijian obviously shortened the latent period of erection in castrational rats after electric stimulus and the latent period of coitus in castrational mice,increased coitus times in castrational mice,increased the appearance rate of sperm suppository in copulated female mice. the acute toxicity tests showed that the half lethal dose(ld50) of weijian was 901.53 mg/kg and 319.60 mg/kg, the long-term toxicity tests showed that large dose of weijian slightly increased the level of glutamic pyruvic transaminase and decreased the glucose,triglyceride and cholesterol of blood, while had no effects on other biochemical factors.

结果： 伟剑能明显缩短去睾丸大鼠的电刺激阴茎勃起潜伏期，明显缩短去睾丸小鼠的性交潜伏期，并增加去睾丸小鼠的性交次数，增加交配后雌性小鼠的精栓出现率；急性毒性试验测得伟剑的口服半数致死量（ld50）为901.53 mg/kg，腹腔注射的ld50为319.60 mg/kg；长期毒性试验研究表明该药在大剂量时可轻度升高谷丙转氨酶，轻度降低血糖、总胆红素及胆固醇，而对其他血液生化指标无影响。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
