精子的

These data strongly suggest that NYD-SP27 is a physiological inhibitor of PLC that acts as an intrinsic decapacitation factor in sperm to prevent premature capacitation and acrosome reaction.

这些数据有力的表明NYD-SP27是一种生理性的PLC抑制剂，它作为精子内的内源性的去获能因子发挥作用以阻止过早的获能和顶体反应的发生。

In addition, spermiogenesis includes chromatin condensation, migration of the cytoplasm and mitochondria to the caudal pole of the nucleus, formation of a moderate axial nuclear fossa containing the proximal centriole and part of the distal centriole and presence of a short cytoplasmic canal separating mitochondria from the flagellum.

另外，精子发生过程中还包括染色质浓缩，细胞质和线粒体向细胞核的尾端迁移，在核的后端中轴位置上形成中等大小的核后凹，近端中心粒和远端中心粒的一部分嵌在核后凹之内，短的胞质内陷管将线粒体与鞭毛分隔开。

The children produced by this cuckoldry, were probably above-averagely good, because the women would have used their powers to get the best sperm, and the fact that they succeeded shows that they were probably fairly high-quality women to start with.

由通奸所产下的孩子往往比平均水平的孩子更加优秀，因为那些女人们用自己的力量获得了最好的精子，而且在一开始她们成功证明了自己很可能是高质量的女人。

"It is important to stress that even if the association between cycling and poor sperm morphology is correct, men training for triathlons are spending much more time in the saddle than the average social cycler or someone who might cycle to and from work."

"值得注意的是，即便骑车会导致精子减少的观点是正确的，骑车爱好者和骑车上下班的男同胞们也不必担心，因为专业运动员的训练强度要比他们高得多。"

If a man does not allow his sperm to fertilise an egg at least once during his lifetime he has no chance of passing on his genes to the next generation, and the genetic line, hundreds of millions of years long, that led up to his appearance on earth is terminated.

如果一个男人不容许他的精子受精的鸡蛋至少有一次在他的一生中，他没有机会通过他的基因给下一代，和遗传路线，数以亿计的年久，导致了他的外观在地球上是终止。

They are not sure why smokers produce fewer boys, but they suspect that sperm carrying the Y chromosome for male children may be more susceptible to the effects of tobacco which could make it less likely to fertilise the woman's egg.

他们无法确定，为什么吸烟者生男孩的可能性较小。但是他们怀疑，决定生男孩的携带y 染色体的精子更容易受香烟的影响，使其与卵子结合的可能性降低。

This paper reviewed the advances in honeybee breeding involving to estimate the numbers of subfamilies in a colony and analyze the genetic correlation among workers; guess the polyandry level of queens and identify the purity of a subspecies; build a linkage map and discriminate loci of quantitative traits; genotype and distinguish full sister from semi sisters; analyze the trend of sperm to inseminate an egg and so on by means of such molecular biotech as microsatellites DNA, mitochondria...

综述了应用微卫星 DNA技术、线粒体 DNA技术、随机扩增多态性 DNA、聚合酶链式反应和 DNA指纹等分子生物技术所进行的蜜蜂育种研究现状。其应用主要包括估计蜂群内亚家系的组成数目和分析工蜂间的遗传相关，推断蜂王的多雄水平和鉴定蜜蜂种性，构建连锁图和区别数量性状位点，鉴定基因型和区别全胞、半胞姐妹以及分析精子受精力的倾向性等

Either of two conjugating gametes that differ in structure or behavior, such as the small, motile male spermatozoon and the larger, nonmotile female ovum.

异形配子在结构或行为上不同的两个配合配子之一，如小的能动的雄性精子与大的不能动的雌性卵子

In the experiments of preservation, the best carbohydrate for spermatozoa preservation was Glucose, then was Saccharose, but the difference between them was not obvious, next was L- Sorbose, next was D -Fructose, the last one was D -Xylose.

在不同糖类进行比较的过程中，发现加入糖后的精子保存液比未加的保存效果要好，但不同糖类的效果又有差别，保存的时间为：葡萄糖〉蔗糖〉L-山梨糖〉D-果糖〉D-木糖。

Here we show that germ cells can be transplanted between two different salmonid species, with the subsequent production of xenogenic, donor-derived offspring.

精子移植的一项新应用有可能被用来恢复濒危的大麻哈鱼的种群数量，以及用于有重要商业价值的鱼类的生产。

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。
