精子的

The rate of morphologically normal sperm and the rate of acrosome intactness were evaluated.

形态正常精子率和顶体完整率是决定精子能否受精的重要因素[1，2]。

The globular acrosome is a very complicated structure and shows PAS positive.

揭示3种蟹精子都是不能游动的无鞭毛精子，呈球形，前后略扁。

Antheridial cell The cell from which the antheridium develops.

精子器细胞：从精子器发育而来的细胞。

After discovery of sperm capacitation,it has made some progress in the aspect of the mechanism of sperm capacitation,yet there are some problems that need future research.

自发现精子获能现象以来，对精子获能机制的研究已取得一些进展，但仍有不少问题需要进一步研究。

The objectives of this study were to investigate the effects of the heparinon the capacitation of bovine sperm cultured in vitro.

本试验在TALP液中添加不同浓度（0、20、40、80μg·ml^-1）的肝素对牛精子进行获能，用CTC染色检测精子获能状况。

In the process of spermiogenesis, the proximal and distal centrioles translocate to the rear of the spermatid nucleus where the proximal centriole is attached, while the distal centriole elaborates the flagellum. The fluorescent centrin protein was seen to be located in basal body of flagellum. But the fluorescent spots could not be detected in the epididymal mature spermatozoa.

在精子变态分化过程中，近端和远端中心粒向核后方移动，近端中心粒附在核后膜上，远端中心粒伸出鞭毛，荧光显示Centrin蛋白位于伸出鞭毛的基部，但在成熟精子中该蛋白消失。

These results showed that the membrane glycoproteins were modified in the epididymis,which is essential for spermatozoa to participate in the process of fertilization.

这说明精子质膜糖蛋白在附睾中不断地被修饰，为精子能完成正常的受精过程做准备。

The Doc said that the water's temperature is warm and sperm could live in this.But it have just lived about 1 or 2 hours.If the women has fetation as this,she would have been winning a prize in a lottery.

医学专家称，温水游泳池温度在30摄氏度左右，适合精子生存，在这种化学环境下精子通常最多只能存活1到2个小时，如果还能适时让游泳的女性怀上身孕，这种概率简直比中彩票大奖还要低。

In the developed world there are a number of options: a process called 'sperm washing', which separates sperm from HIV-causing agents before being used for insemination, is safest for couples where a positive man wants to avoid the risk of infecting his negative female partner or reinfecting his positive partner; artificial insemination is the safest way of conceiving for couples with a positive woman and a negative man.

在发达国家他们会有许多选择：&精子洗涤&，即在受精前将精子与引起HIV的物质分离，这样可使阳性的男性避免传染阴性的女伴，或再传染给阳性配偶，对于这种情况，&清洗精子&是最安全的；人工授精，这对于由阳性女伴和阴性男伴组成的夫妇来说是最安全的生育方式。

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。
