精子的

Sperm capacitation is an essential mature process before mammalian fertilization. Making sperm capacitated in vitro is an important prerequisite to complete fertilization in vitro.

精子获能是哺乳动物受精前必须经历的一个成熟过程，所以精子的体外获能便是实现体外受精的一个重要前提。

The testis which was ignored by previous authors consists of nine finger-shaped lobes on each.

在一次发育期中精子的发生大约持续两个月，产生的精子量大；雄虾具有多次交配的能力。

The role of nicotine smokers breathe in the production of sperm in the seminiferous tubules of spermatogenic epithelium to spermatogenic dysfunction, which produced a decrease in the number of sperm quality lower.

吸烟者吸入尼古丁作用于生产精子的曲细精管的生精上皮，使其生精功能减退，因而生产出来的精子数目减少，质量降低。

That indicates there might be differences in respiring and feeding between diploid and triploid Pacific oysters.

二、对四倍体牡蛎精子的透射电镜观察结果表明，四倍体太平洋牡蛎的精子的形态结构与其二倍体基本相同，都是由头部、中段和鞭毛三个部分组成。

At least in rodent species, activation of sperm mitochondria appears to be a particularly important part of epididymal maturation.

至少在啮齿类动物中精子线粒体的活化对精子的附睾内成熟起到十分重要的作用。

It is probably that there were not Ca〓 channel on the guinea pig sperm PM, because the Ca〓 channel blockers verapamil, nifedipine, diltiazem and D600 promoted acrosome reaction in synchronous and nonsynchronous cultural systems.

豚鼠精子质膜可能无Ca〓通道，因为verapamil、dilliazem和D600等对获能和未获能的精子的顶体反应均具有显著的促进作用。

The results were as follows sperm vigor parameters were all decreased in 12 patients, whereas, pattern parameters had no singnificant difference. By SEM, the results were as follows: infertility group acrosomes were much more bigger than the normal ones.

结果发现，不育症精子的运动参数：活率、活动力、平均径速度明显下降，而运动方式参数直线分离度却无明显差异，进一步用扫描电镜观察其头颈部，特别是顶体的超微结构，发现不育症精子顶体较大。

As it required 3-h incubation in vitro under capacitation conditions to release motile sperm from the bundles, it is suggested that the monotremes provide an example of capacitation that is quite different from capacitation in higher mammals.

在体外获能条件下培养3个小时后运动的精子分离开，这表明单孔动物精子的获能与高等哺乳动物区别很大。

Objective To evaluate the binding characteristics of the synthesized anti-sperm polypeptide (35 peptide) antibody on the surface of human sperms.

目的 对人工合成的精子多肽( 3 5肽)抗原抗体与人精子的结合情况进行评价。

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。
