Whereas, as the special structure of rat spermatozoa, the successful cryopreservation protocol of its spermatozoa is very difficult.

而大鼠精子因为其结构的特殊性，目前仍未建立成熟的冷冻保存技术。

Furthermore, urogential inflammation could also disturb the expression of TNF-α in human spermatozoa.

泌尿生殖道感染及炎症也可能影响精子TNF-α的表达，其机制和意义有待进一步的研究证实。

Our results indicated that Y-encoded genes'mRNAs were reserved selectively in mature spermatozoa.

以上结果说明成熟精子对Y染色体编码的基因mRNA是选择性保留的。

The activation and motility of spermatozoa from Chinook salmon collected by dissection were studied under different reactivators,ASP,pH and temperature.

采集成熟的大鳞大马哈鱼精子，在不同的激活介质、人工精浆、pH和温度条件下进行活力观察。

Moreover, the extremely slow development of gametophyte and time interval between the appearance of antheridia and archegonia resulting from the inherent physiochemical property of red soil make it impossible to fertilize and generate sporophyte.

此外，红壤固有的理化性质导致扇蕨配子体发育极其缓慢、精子器和颈卵器发生的时间间隔过长使其不能受精产生于包子体。

The fertilization was processed by sperm in mature male gametophyte combining with egg cell on the top of archegonia on June 15 or so.

摘要樟子松发育成熟的雄配子体中的精子6月15日左右在颈卵器中上部与卵细胞结合，进行受精作用，其后，受精卵进行游离核分裂，形成8个子核时，开始形成细胞壁。

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。
