核仁

The results show that, with the maturity of the gonad, the undifferentiated germ cell divided and differentiated to smaller oogonium or spermatogonia, and the oogonium or spermatogonia transformed to oocyte and sperm undergoing a series of maturation process.

摘 要 通过观察栉江珧的未分化生殖细胞，精原细胞和卵原细胞，精母细胞和卵母细胞，精子和卵子的形态结构与分布状况及核仁在卵成熟过程中的变化，对栉江珧生殖细胞发生及成熟过程的有关问题进行了探讨。

According to the size and shape of oocyte, the morphology of nucleolus, the growth of yolk and the structure of follicle, oogenesis of H. d. supertexta can be divided into three stages as follows: oogonium, previtellogenic oocyte and vitellogenic oocyte. The ovary wall is composed of tunica adventitia and germinal epithelium which will produce oogonia and follicle cells. The follicle is the structure unit of ovary.

根据卵细胞的大小、形状，核仁的形态，卵黄颗粒的积累情况，滤泡的结构等，将九孔鲍卵子的发生分为卵原细胞、卵黄发生前的卵母细胞和卵黄发生期的卵母细胞3个时期；卵巢壁由外膜及内生殖上皮构成，生殖上皮分化产生卵原细胞和滤泡细胞；卵巢的结构单位是滤泡。

According to the size and shape of cells,nuclei and nucleoli,and to the NPand the vitelline accumulation,the oogenesis can be divided into five phases:oogonium phase,small growth phase,large growth phase,pro- maturation phase and ma...

卵子发生根据卵细胞、细胞核及核仁的大小形态、核质比和卵黄积累情况可分为：1。卵原细胞期：2。小生长期；3。大生长期；4。成熟前期和5。成熟期。卵巢发育则根据第一批卵细胞的发育情况、卵巢长度及颜色分为五期，大致可归纳为三个阶段：5～7月为延缓期；8～11月为对数增长期：12～4月为稳定期。

In rare cases, mild nuclear pleomorphism, prominent nucleoli and mitotic figures may be seen.

少数病人可见多形性胞核、突起的核仁和有丝分裂像。

The oocytes and early embryos treated by other three methods were out of sharp and the structure of nucleolus、ZP and polar body in different stages were damaged.

其它3种方案处理后卵母细胞的形态变形，各发育时期的核仁、透明带、极体等结构受到不同程度的破坏。

Plenty of pseudopod sublobe displayed on the surface of cell, with one or two nucleoli, which posses basically complete organelle structure.

细胞表面有较多伪足，有一两个核仁，有分叶，具备正常细胞器结构。

Membrane reconstruction, nucleolar re-formation, at the same time cytokinesis.

核膜重建，核仁重新形成，同时进行细胞质分裂。

Fiber similar spindle-shaped cells, equality configuration, or egg shape slender shape of nuclei, nucleolus well developed.

纤维型细胞类似纺锤状，平等构形，有蛋形或细长形的细胞核，核仁发育良好。

The localization of 〓 changed during the process of rat oocytes maturation. In GV stage oocytes,〓 was concentrated in GV but it concentrated around chromosomes from metaphase Ⅰ to telophase Ⅰ.

〓的在大鼠卵母细胞内的定位随成熟分裂的过程而变化：在GV期生发泡内核仁周围有特异分布，在成熟分裂的中期至末期〓在染色体周围区域有特异分布。

Chromatin has been set shrunk to thin linear structure, each chromosome and the nuclear membrane through the attachment plate connected to increase the size of this nucleus, nucleolus rate as well.

染色质已集缩成细长的线状结构，每条染色体通过附着板与核膜相连，此期核的体积增大，核仁也较大。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
