雌雄

The sex ratio of the pupae was nearly 1:1 in the woodland samples.

在调查样地中，雌雄蛹的比例基本为1：1。

Even our nearest relations, the quadrumana, exhibit every possible variation in the grouping of males and females

甚至我们的近亲──猕猴类，在雌雄的配合上也显露了种种可能的差别

Apart from an androgynous singer, a sackful of killer lines and some seriously messed-up pop songs, there's also The Voice.

除却雌雄莫辨的主唱，大量的富有残忍意味且纷杂混乱的音乐，当然还有"嗓音"。

Thirty New Zealand white rabbits of either sex,weighted varied from 1.9 to 2.3 kg,were randomized into two groups,named as the control(physiological saline 4 mL/kg) and rhodiola sacra SH Fu group(0.5 g/4 mL · kg-1),15 rabbits in each group.

新西兰大白兔30只，雌雄不限，体质量1.9～2.3 kg，随机分为2组，对照组(生理盐水4mL/kg)和红景天组(0.5 g/4 mL·kg-1)，每组15只。

This paper summarized the experiments which support or negate the existence of female sterility,analyzed the experimental ideas and inference methods of these experiments,especially Sano' s;and concluded that the conclusion that the hybrid sterility is only caused by male or female sterility is a one - sided view,therefore attention should be paid to the genetics of both female and male sterility.

本文对证明水稻亚种间杂种存在和不存在雌性不育的研究进行了综述与分析，从中可以看出无论是认为水稻亚种间杂种不育性表现为雄性不育还是雌性不育的结论都有一定的片面性；尤其是Sano证明基因座S-5不存在的研究存在较大的缺陷。因此，水稻亚种间杂种雌雄配子败育对小穗育性影响的大小有待进一步研究。

Self-fertilization involves male and female gametes produced by the same, hermaphrodite individual, Self-compatibility is a means by which sessile and less mobile organisms' such as plants, that are unable to actively seek mates, insure against failure to cross=fertilize.

自体受精是雌雄同体的个体同时产生雌雄配子。对于营固着生活和运动能力很弱的生物，例如植物，它们不能主动地寻找配偶，自我兼容性是确保其不发生异体受精的一种方法。

The morphology of sensillumtrichodea does not differ between sexes and species,but the number anddensity differ significantly.The ultrastructure of two types of antennal sensillum,sensillumtrichodea and sensillum chaetica was investigated in males of Ancylissativa Liu with transmission electron microscope.

在七种类型的触角感器中，毛形感器在数量和分布上占主导地位，雄蛾触角上毛形感器的数量和密度比雌蛾触角上多而密，不同种类之间毛形感器的数量、分布密度也不同；其它六种触角感器虽然在同种的雌雄之间和不同种类之间也存在一定的差异，但不如毛形感器显著。

The types,morphology,number,distribution and density of antennalsensilla in five leafroller moths species,i.e.Ancylis sativa Liu,Aclerisfimbriana Thunberg,Grapholitha molesta,Spilonota lechriaspisMeyrick and Adoxophyes orana Fischer von Roslerstamm,were observedwith microscope and electron microscope.Seven types of sensillum,i.e.sensillum trichodea,sensillum chaetica,sensillum coeloconica,sensillumstyloconica,sensillum squamiformia and Bohm's bristles were present inboth sexes and all five species.The number and density of sesillum trichodeaare much more than other types of sensillum.

用扫描电镜和相差显微镜对枣粘虫Ancylis sativa Liu、黄斑长翅卷蛾Acleris fimbriana Thunberg、梨小食心虫Grapholitha molesta、芽白小卷蛾Spilonota lechriaspis Meyrick、棉褐带卷蛾Adoxophyes orana Fischer von Roslerstamm五种卷叶蛾触角感受器的类型、形态、数量、分布、密度进行了观察，结果发现在所有五种的雌雄成虫触角上都具有七种类型的感受器，它们是毛形感器、刺形感器、腔锥感器(S.coeloconica)、栓锥感器(S.styloconica)、鳞形感器(S.squamiformia)、耳形感器(S.auricillica)和Bohm氏鬃毛(Bohm's bristles)。

Most of the endangered plant has the difficulty in sexual reproduction.

大多数的濒危植物都存在有性生殖障碍，通过对珙桐的大小孢子及雌雄配子体形成的研究，发现在这一过程没有异常。

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。
