母

He mentioned this to the goose, who was sitting quietly in a corner of the sheepfold.

他跟母鹅谈到了这事儿，当时母鹅正安静地坐在羊栏的一个角落里。

With this nature, we can discretize a structure into several main elements, each of which is then subdivided by the computer into several sub-elements geometrically simitar to one another.

由这一性质我们可将结构分成几个大块母元，然后由计算机再将每个母元细分成若干个彼此相似的子元。

The results show:(1) In testis, PNA receptors sites were firstly observed in the cytoplasm and plasma membrane of primary spermatocyte, and greatly increased in the plasma membrane of second spermatocyte, then decreased and were accumulated in the tail of the round spermatid. The same reaction was observed in sperms of testis and spermatheca, which shows stronger reaction in head and weaker in tail. A universal dyeing was observed on the plasma membrane of sertoli cells.

结果表明：(1)在中华蚱蜢的精子发生中，PNA受体是由初级精母细胞合成，然后转移到膜上，在次级精母细胞，由于量的积累其质膜出现了强阳性标记；从早期精子细胞到成熟精子时期糖蛋白的分布发生了明显的修饰变化，这些变化与精子获得与卵子进行识别、粘附、结合等受精能力密切相关：受精囊内与精巢内的精子表面的标记是相同的，说明质膜糖蛋白的修饰作用在精巢内就已完成。

According to the change of chromatin and morphology of cells, the spermatogenesis could be divided into five stages: spermatogonium, primary spermatocyte,secondary spermatocyte, spermatid and spermatozoon.

利用透射电镜观察秀丽白虾的精子发生，并根据染色质及细胞形态的变化将精子发生的全过程划分为五个时期，即精原细胞、初级精母细胞、次级精母细胞、精细胞和精子。

According to the changes of the structure of chromatin and the morphology of cell, the process of the typical spermatogenesis of Cipangopaludina chinensis can be divided into five stages: spermatogonium, primary spermatocyte, secondary spermatocyte, spermatid and mature sperm.

中国圆田螺典型精子发生时，根据染色质和细胞形态的变化，可将其发生分为以下五个时期：精原细胞、初级精母细胞、次级精母细胞、精细胞和成熟精子。

The spermatogenesis includes five stages: spermatogonium、primary spermatocyte、secondary spermatocyte、spermatid and spermatozoon.

雄体的生殖细胞发生经历精原细胞、初级精母细胞、次级精母细胞、精子细胞和成熟精子五个时期。

These results indicated that CB is necessary for synchronization in spindle formation in both oocyte and primary spermatocyte, and that synchronization may be required for subsequent embryo development.

这一结果表明CB的处理可以使精母细胞与卵母细胞同步形成MI纺锤体，使其发育同步，这可能对以后胚胎的发育具有重要作用。

Its development as follows: spermatogonia → primary spermatocyte secondary spermatocyte →→→ sperm sperm cells.

其发育过程为：精原细胞→初级精母细胞→次级精母细胞→精子细胞→精子。

Previous studies have demonstrated that primary spermatocyte can undergo meiotic divisions in MI oocytes and the resulting embryos can develop to term. However, the success rate is very poor.

已经证明初级精母细胞在显微融入MI卵母细胞后可以完成减数分裂并且产生的胚胎可以发育到期，只是发育率还非常低，作为一种形式的核移植，细胞周期的同步化处理对于胚胎的发育具有重要意义。

Although osmiophillic layers also developed between spermatocyte and gametophytes, they were interrupted by pores for substance and signal exchanges.

尽管精母细胞之间也有嗜锇层的形成，但嗜锇层是不连续的，其上有一些空隙，精母细胞之间可通过空隙进行物质和信息的交流。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
