The results showed that there was no remarkable difference of reproductive hormone between the idiophase and non-idiophase, which established the theory foundation for the reproductive endocrinology and the artifical breeding of Andrias davidianus, was made.

实验结果表明，雌雄性中国大鲵在繁殖期间与非繁殖期间的6项生殖激素检测结果没有明显的差异，对中国大鲵血清中的生殖激素与繁殖期的相关性进行了初步探讨，为中国大鲵生殖内分泌学的研究和人工繁殖积累了资料。

Most of melon were andromonoecious, monoecy can not only reduce the hand pollination but also can improve the quality of F1 hybrids than other andromonoecious accessions.

大多数甜瓜是雄全同株材料，而雌雄异花同株材料除了在育种过程中能减少大量复杂的去雄工序外，其F1果实发育也要强于雄全同株材料。

Shrubs (sometimes scrambling or rarely somewhat climbing) or rarely small trees, monoclinous or andromonoecious, armed or unarmed, apparently without oil glands.

Parental lines were: female parent 3-2-2 from China, thin-skinned melon, monoecious; male parent TopMark, from USA, thick-skinned and netted melon, andromonoecious; tested parent WI998, from USA, netted melon, gynoecious.

本试验选择亲本材料分别为：母本3-2-2，来自中国，薄皮甜瓜，雌雄异花同株材料；父本TopMark，来源美国，厚皮网纹甜瓜，雄全同株材料；检验亲本：WI998，来源美国，网纹甜瓜，全雌株材料。

In this study, the external morphology, types, and distribution of antennal sensilla in both male and female of this beetle were described using the scanning electron microscope.

本研究利用扫描电镜对红头芫菁雌雄成虫触角感器进行了观察，描述了触角感器的外部形态、类型和分布，并结合文献资料对其功能进行了讨论，试图解析其触角感器在寄主选择行为机制。

The Antennal ultrastructures of the two closely related wasp species, Aprostocetus prolixus and Aprostocetus fukutai, were observed by scanning electron microscope. The types, numbers, morphological characteristics and distribution patterns of the antennal sensilla of the two species were described, and the differences between two sexes were compared too.

利用扫描电镜观察了同属的桑天牛卵啮小蜂和桑天牛长尾啮小蜂的触角感器，对这两种寄生蜂触角感器的种类、形态、数量及分布进行了描述，并对雌雄两性触角之间的差异做了比较。

The results of The biological characteristics of Semanotus bifasciatus have showed: 1. The hole of Semanotus bifasciatus associated with a certain temperature.2.The main damages of Semanotus bifasciatus located oriental arborvitae tree trunks, while above 3m parts are not damaged. 3.The Mating numbers of Semanotus bifasciatus are not unique ,and the duration varied due to the different individuals, the average duration is 3.2 minutes . 4. when are flying , they are more sensitive to blue and green; while moved, they are more sensitive to black.

对双条杉天牛的生物学特性的研究结果表明：双条杉天牛出孔与温度有一定的相关性，温度过低，双条杉天牛停止出孔；对于树高7m以上的树，主要危害侧柏基部的1-3m的主干部分，3m以上基本不受害；双条杉天牛需要经过一段时间的抱合才能交尾，交配对象不专一，雌雄成虫均可以多次交尾，交尾时间长短不一，平均3.2min/次；飞行时对蓝色和绿色较为敏感，爬行时对黑色较为敏感。

Assortative mating Sexual reproduction in which the pairing of male and female is not random.

选型交配：有性生殖中配对的雌雄双方不足随机交配的现象。

Methods: 28 goats (total 56 tibia), 12-month-old,no limit on male or female, 15~18kg.24 goats of them were were divided into three groups — experimental group A: allograft tubiform bone with autoallergic cancellated bone stuffed in.

28只成年山羊(实验组24只，对照组4只)，12月龄，雌雄不限，体重在15～18kg，共56根股骨分四组——实验组A：同种异体骨管＋管内自体松质骨；实验组B：同种异体骨管＋管内脱钙骨基质混合自体红骨髓；实验组C：同种异体骨管＋管内重组合人工骨；对照组：单纯同种异体骨管。

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。
