交配的

We briefly reviewed the mating system of insects with emphasizing a historical research on the sexual selection conducted by Bateman.

简要回顾昆虫交配系统的研究历史，并简述 Bateman的性选择原理，讨论雌雄昆虫在交配过程中的角色和性选择压力的相对关系。

Possible and this correlation is, the more than half Sumatranorangutan's copulation is the coordination, but in Borneo, 90%copulation activity all is through the violence realization.

可能与此相关的就是，过半的苏门答腊猩猩的交配是配合的，而在婆罗洲，90%的交配活动都是通过暴力实现的。

In the nineteenth century, the most widely credited example was that of lord morton's mare, reported by the distinguished surgeon sir everard home, and cited by charles darwin.[4] lord morton bred a white mare with a wild quagga stallion,[5] and when he later bred the same mare with a white stallion, the offspring strangely had stripes in the legs, like the quagga.

在19世纪时期，被引用最多的例子来自lord morton的母马，是被外科医生everard所发现的，后来又被达尔文引证。lord morton把一匹白色母马和一匹种斑马交配，而后他又将同样一匹母马与一匹白色种马交配，它们的后代奇怪地在四条腿上带有条纹，就象那匹斑马。

Now we are seeing the pretty rare Lion-tiger animal who came from Korea, the generation of a female lion and male tiger. They can copulate because they belong to felid, but the child of them cannot raise anymore and has no biology value. There are only 10 lion-tigers in the world, and the surviving ratio is just 3‰.

现在我们看到的是极其罕见的狮虎兽，它产自韩国，是由雄性狮子和雌性虎交配后所产的后代，因同属猫科动物所以能达到交配，它同马和骡子杂交的后代骡子一样，并不具有下一代繁育的能力，并没有生物学价值，全世界狮虎兽只有10余只，成活率是千分之三左右。

It were analyzed DNA polymorphism in baby rats between outbred Wistar and SD rats with 30 microsatellites DNA loci of PCR amplification. And was breeding baby inbred rats using high and middle of Coefficient of similarity with female SD rats of F0. It was indicated that there were hybrid and polymorphism loci, there weren't homo-gene loci of F2. It were monomorphism homo-gene for 27, rate of homo-gene loci for 90%.

利用PCR扩增30个微卫星DNA位点对封闭群SD和Wistar大鼠交配繁殖的仔代鼠进行微卫星DNA多态性分析，仔代中与母代SD大鼠相似系数高的与中的进行定向交配繁殖。F2代大鼠均为杂合多态的位点，没有纯合位点；到F9代时基因纯合位点达27个，纯合基因位点率为90%。

The results showed that the sex ratio of pupae and adults is 1:1.0430 and 1:1.0154,respectively.The 80% beet armyworm emerged generally during night after pupation about 4~8 d,and more than half in 0:00~8:00 am.

结果表明：甜菜夜蛾蛹的性比为：1：1.0430，羽化之后的成虫性比为1：1.0154；甜菜夜蛾羽化集中在化蛹后4￣8 d，且化蛹具有显著的昼夜分布特点，夜间羽化数占总数的80%左右，其中0：00￣8：00之间羽化数达一半以上；成虫单次交配持续时间为40￣100min的发生概率占70.44%，85%以上的交配集中发生在夜间2：00￣7：00；成虫主要在夜间产卵，其中在0：00￣5：00时辰占65%以上。

In the laboratory,unmated females were placed with randomly chosen males to determine whether,given the opportunity,females would be found mating with the largest available males. I exposed amplexing pairs to other males to determine if larger or smaller males would displace amplexing males.

在实验室内，令未交配雌体选择随机选出的雄体，观测雌体是否与最大的雄体交配；将抱对的蛙暴露于其它雄蛙，观测其它较大或较小的雄蛙是否取代已抱对的雄蛙。

The results suggest that (1) sexual experience has no effects on behaviors related to paternity guard, but influences male investment in copulatory plug, and (2) the strategy for virgin male to win in sperm competition is to increase the intensity of mating guarding.

这意味着性经历对于保证父亲确认程度的行为方式无影响，但能影响到交配雄兽在繁殖中对交配栓的投资；无性经历雄性在精子竞争中获胜的策略为加强对配偶的守护。

In contrast,ZHJ2 males interfered more successfully with courtships initiated by males of the same biotype than those initiated by B males.B males could guard females post copulation,and more effectively inhibited courtships from a ZHJ2 male than from a B male during guarding.

这些求偶互作行为使得ZHJ2型雄虫的存在提高了B型雌雄之间的交配次数，相反，B型雄虫的存在使得ZHJ2型雌雄之间的交配次数减少。

Relating to, produced by, or involving reproduction that occurs without the union of male and female gametes, as in binary fission or budding.

无性生殖的没有雌雄交媾而繁殖的，关于无期雌雄交配而繁殖的，涉及无雌雄交配而繁殖的，如在偶数分裂或萌芽中

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。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
