精子的

During capacitation Ca〓 was present on the outer surface of IAM and in the released acrosomal contents.

精子获能前内存Ca〓主要分布于顶体外膜内侧和顶体内膜与核膜之间，并在获能和顶体反应过程被动员利用；顶体反应精子Ca〓分散存在于释放的顶体内容物中和结合于顶体内膜外侧，可能与顶体酶的活性有关；（9）。

Compared with the control group,after ig125 mg/(kg·d sasanqua saponin sterilant for 4 weeks,(92.1%) alive sperm and(52.6%) sperm motility on male mice could be obviously reduced,and(64.0%) gravidity rate and(67.4%) alive embryo on female mice could be significantly decreased.

与生理盐水对照组比较，125 mg/油茶皂素不育剂灌胃给药4周后，可以明显降低雄性小鼠的活精子数(92.1%)和精子活力(52.6%)，可以显著减少雌性小鼠的妊娠率(64.0%)和活胎数(67.4%)。

Results indicated that, just like the homologous sperm of summer flounder, the cryopreservative sperm of Lateolabrax japonicas could induce diploid gynogenesis of summer flounder.

实验表明：犬齿牙鲆同源精子经80 mJ/cm2 的紫外线照射可以完全失活，冻存花鲈精子经紫外线照射后也同样具有诱导犬齿牙鲆雌核发育的能力。

Results In the medium and high dose F0 groups, it was observed that the atrophy and incrassation of seminiferous tubule, decrease of spermatogenesis, hyperplasia of interstitial tissue, especially in high dose groups spermatozoon abnormality and nucleolus concentration in the rats testis after DU ingestion for 14 months. The changes became more severe with the prolongation of DU ingestion. Such changes occurred in filial rats (F1) after DC ingestion for 5 months. In the medium and high dose F0 groups, it was observed that a little atrophy of kidney glomerulus, hyperplasia of interstitial tissue after DC ingestion for 14 months, and kidney glomerulus fibrosis happened after DC ingestion for 20 months, such changes occurred in filial rats (F1) after DC ingestion for 5 months In the medium and high dose F0 groups, splenic germinal center and periarterial lymphatic sheaths were hyperplasia , companies with lymphopoiesis after DC ingestion for 7 months, splenic white pulp became more small and sparse after DC ingestion for 20 months.

结果 F0代的中、高剂量组大鼠摄入贫铀14个月后可见雄性的精曲小管萎缩，管壁增厚呈空虚网状，生精细胞层次减少，间质细胞增生，但仍见有精子生成；高剂量组可见到精子呈异型性改变，细胞核浓缩深染，且随着摄入时间延长改变愈趋明显；F1代大鼠摄入贫铀5个月后就有上述改变且更为严重。F0代中、高剂量组大鼠摄入贫铀14个月后肾小球轻度萎缩，间质增生明显，20个月时肾小球萎缩纤维化；F1代大鼠摄入贫铀5个月后就有上述改变。F0代中、高剂量组摄入贫铀7个月时脾脏生发中心和淋巴鞘增生，淋巴母细胞增生活跃，20个月时脾小体减少，生发中心稀疏；F1代大鼠摄入贫铀早期和晚期有类似改变。F0和F1代高剂量组摄入贫铀早期肝脏有炎症细胞浸润，晚期骨髓有核细胞减少，脂肪细胞增加。

They haven't created a master race because only a tiny number of women have wanted to impregnate themselves this way.

但是一个优等民族并没有因此而产生，因为需要借助精子库内的精子怀孕的育龄妇女毕竟是极少数。

The functional study of sperm-related proteins plays a key role in discovering the molecular mechanisms of sperma...

精子蛋白质的功能研究对于揭示精子发生及受精过程的分子机制有重要意义。

The reproductive toxicity of Aroclor 1254 on the oogenesis, the fertilization and preimplantion embryonic in vivo in female mice, the spermatogenesis toxicity, the sperma fertilizing ability and the zygote developmental toxicity in vivo in male mice were studied, and the toxicity mechanism were discussed by histopathological examination of the ovary, the uterus, the testis and epididymides.

以小鼠为动物模型，研究了类二噁英多氯联苯的典型代表物质——Aroclor 1254对母鼠卵子发生、受精和附植前胚胎体内发育毒性，公鼠精子发生毒性，以及对精子受精能力和受精卵体内发育的毒性。

So it could be inferred that seminal plasma and spermatophore matrix had nutritional effect onsperms. But it would need further study to clarify the real function of spermatophore matrix.

这一实验结果与精液的营养功能一致，同时也表明，精荚基质除了对精子具有保护作用外，还可能含有精子在其中进行新陈代谢所需要的营养物质。

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。
