Investigation of the proteins interaction and their signal transduction during the process of sperm acrosome reaction is extremely essential for the further understanding of the molecular mechanism of fertilization.

研究精子顶体反应过程中相关分子作用的信号传导通路，对进一步深入了解受精的分子机制具有重要的影响。

The researchers found no consistent associations between intakes of zinc and the other vitamins and sperm aneuploidy.

研究人员发现，没有一贯的社团之间的摄取的锌和其他维生素和精子异常。

It is motile and is produced in an antheridium, except in certain gymnosperms (e.g.Cycas, Ginkgo) in which antherozoids develop from the generative cells of the pollen tube.

除了在一些由花粉管的生殖细胞产生配子的裸子植物中（铁树 Cycas，银杏 Ginkgo ），通常是由精子器产生的并且会游动。

One of two sperm get into an archegonium and fused with egg. The nucleus of fertilized egg began to divide, and the walls were formed after the third division. The eggs without fertilization divided two times and then disappeared.

雄配子体产生的两个精子中的一个进入颈卵器与卵细胞结合形成受精卵，受精卵核到第3次分裂形成细胞壁，没有受精的卵细胞还要进行两次有丝分裂后才消失。

The histological structure shows the lobule testis in Leptobotia elongate Bleeker, and the spermatogenesis is divided into 6 phases based on the size, nucleolus number, the degree of nucleus and cytoplasm condensation.

组织学结构显示长薄鳅的精巢属于小叶型，根据发育过程中细胞的大小、核仁多少、细胞核和细胞质浓缩的程度将精子发生划分为6个时相。

Fertilization antigen 1 (FA-1) is an evolutionarily conserved antigen present in sperm of various mammalian species including mouse, rabbit, bull, rhesus monkey and human. It seems to have similar function and, shown to have cross-reaction among these species.

受精抗原1(Fertilization Antigen 1)是一在进化上比较保守的抗原，在多种哺乳类动物包括小鼠、家兔、牛、猕猴以及人的精子表面均存在，并具有相似的功能，FA-1在不同物种间存在交叉反应。

But as a result of the animal work, says Culver,"the technology is there" for engineering human sperm.

但卡尔弗说，作为动物实验的成果，"就有了现成的技术"来改造人类的精子。

Therefore to elicit the functions of the proteins is of great value to delineate the mechanism of spermatogenesis.

因而，揭示这些睾丸生精细胞特异表达蛋白的功能对于阐明精子发生的机理是极其重要的。

Therefore to elicit the functions of these proteins is of great value to delineate the mechanism of spermatogenesis.

因而，揭示生精细胞特异表达蛋白的功能对于阐明精子发生的机理具有极其重要的价值。

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。
