卵子

It is both an impression of time and space, as well as the material accouterments of our world.

即使是时间、空间的变幻也在这儿成了附着物——石子儿可以成为人对生命进行关怀和形态理解的喻体：石子儿之小，犹如涅槃痕迹舍利子，有收缩、回归的生命意象；石子儿之大，犹如卵子带来生命的繁衍与扩张

In vitro, the acrosome reaction of sperm does not influence the ovum fertilization rate.

在体外，精子顶体反应率的高低与卵子受精率没有明显的相关性。

The first contact of the sperm head with the egg's jelly coat triggers the acrosome reaction, in which enzymes

当精子和卵子的胶状膜发生接触时，触发了顶体反应。

Objective To investigate the relationship between ovum fertilization rate and sperm morphology, acrosome reaction in IVF and to explore the influence of parameters of sperm on fertilization rate.

目的 研究体外受精(in vitro fertilization，IVF)中精子形态、顶体反应与卵子受精率之间的关系，分析精子各参数在IVF受精率方面的参考意义。

The gamete is greatly specialized in the structure and function, and there are many kinds of agglutinin receptors in the plasma membrane, former studies indicated that the receptors may be associated with their roles in ovum recognition and fusion.

动物的精子和卵子是两类结构和功能均十分特化的细胞，其膜表面存在着多种凝集素受体，它们在精卵识别与融合中起着重要作用。

Experiments show that:"Crown 3000" not only increases spermatogenic function effectively and prolongs fertility, but also prevents anaplasia of spermary and ovum effectively, and prolongs the coming of menopause and senescence process and keeps vigor of body.

试验表明："顶点 3000"不但能有效增强生精功能，延长生育能力、还能够有效阻止睾丸和卵子退行性变化，延缓更年期的到来，延缓衰老进程，保持身体活力。

When sperms and eggs are formed, only one of each chromosome pair enters the sperm or egg.

当精子和卵子的形成，其中只有一个，每个染色体配对进入精子或卵子。

By three days after injection, the number of embryos which had cleaved to the 2-cell stage was 0 with round spermatids and mree(17.6%) with elongated spermatids.

结果在培养的 3 d中，ROSI的卵子没有发生卵裂，＆ ELSI的卵子中有 3个服至 2细胞期O7.6O）。

Male infertility, female fertility and extrapair copulations

这种状况叫多精入卵，结果毁了卵子和卵子的受精机会。

They are the result of two sperm cells fertilising a single egg, which then divided to form two embryos - and each sperm contributed genes to each child.

他们是两个精子细胞与一个卵子结合的结果，结合后的卵子分裂形成了2个胚胎——各自精子对各自幼儿提供基因。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
