雌雄生殖

Locusts, some caterpillars, castes of social insects, alary polymorphism in crickets, aphids and other Homoptera, and color polymorphism of butterflies are examples of insect polymorphism.

同一性别昆虫，还可分化成具有不同形态和生殖机能的，或在其&家族&中负担不同职能的个体群。蚂蚁、白蚁、蜜蜂等社会性昆虫，除雌雄二型外，还有职蚁和职蜂。

Diagnostic characterisitics of adult were described. A mature nest is alveolate,and form big mound with (26.00±7.42) cm high,and (82.00±41.04) cm diameter on average of thirty random samples. which size far excess of other ants'.

蚁巢中可见蚁后、工蚁和兵蚁，生殖季节可见雌雄婚飞蚁；成熟蚁巢为蜂窝状，并突出地面形成高大蚁丘，随机测量30个，平均高(26.00±7.42)cm，平均直径(82.00±41.04)cm。

An organism, such as an earthworm or a monoclinous plant, having both male and female reproductive organs.

雌雄同体兼有雄性和雌性生殖器官的生物体，如蚯蚓或雌雄同花的植物

This breakthrough in understanding proides an opportunity to address any number of extremely interesting questions regarding eolution of oogamy and the origins of male-female dichotomy.

这一认识上的突破为我们提供了一次对许多饶富趣味的问题进行提问的机会，象是异配生殖的进化啦，又或者是雌雄划分的起源啦。

Continuous observations using the video recording system showed that in the three biotypes,the earliest copulation events occurred 2-6 h after emergence and 56-73%of females copulated at least once by 12 h after emergence.

3B型烟粉虱与ZHJ2型烟粉虱的生殖隔离程度与同型雌雄虫之间的交配次数和频率相比，B型烟粉虱和ZHJ2型烟粉虱之间的交配次数显著减少，交配频率显著下降。

Their offsprings' body weight, body length, tail length and the time of auricle separation, teeth burgeon, eye opening, ear hole opening, hair appearance were measured. Then 64 offsprings (8 each group, half female and half male) were killed when they were 70-day-old and the same indexs as pregant rats' were measured.

另一半孕鼠正常分娩，仔鼠出生后测量体重、身长、尾长，观察耳廓分离、门牙萌出、睁眼、张耳及出毛情况；70天龄时称重并处死64只仔鼠，每组8只，雌雄各半，分别测定脏器重量、血清生殖激素、甲状腺激素和免疫学指标。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
