Oogonium develops into early oocyte in the ovary, and then the oocyte leaves the ovary for the coelomic fluid in the form of single cell or cell mass followed by the rapid separation of the group of oocytes into individual ones. Oocyte enters into the nephridium after its maturation. The rupture of germinal vesicle marks the oocyte maturation. Oocyte in the coelom does not have follicle membrane and vitelline membrane is formed and developed by the oocyte itself. Smaller oocyte (0μm in diameter) is round, and larger ones (≥60μm in diameter) is ovate. The short and long diameters of a morphologically mature oocyte are about 115—120μm and 140—145μm respectively, and the vitelline membrane is 7—9μm thick.

卵原细胞在卵巢中发育至早期卵母细胞时期单个或成团脱离卵巢入体腔液中，卵母细胞团细胞很快分离为单个细胞；卵母细胞在体腔液中发育成熟后进入肾管；生发泡破裂是卵母细胞成熟的标志；体腔中卵母细胞无滤泡膜，卵黄膜的形成与发育靠卵母细胞本身；卵径小于60μm的卵母细胞呈圆形，卵径大于60μm 的卵母细胞为卵圆形，形态上成熟的卵母细胞短径约115—120μm、长径约140—145μm、卵黄膜厚7—9μm。

In addition, using RT-PCR to detect expression of centrin homogene during Urechis unicinctus spermatid deferentiation and early embryonic development. The result revealed that (1) expression of HsCEN1 homogene is present during spermatid defferentiation including spermtid and sperm, but not in adult tissues including body wall tissue,intestinal mucous memberane cells and cell in coelom succus;(2) expression of HsCEN1 homogene is not present in unfertilized oocytes but present in that of released polar bodies after fertilization and parthenogenesis oocytes treated with A23187;(3) expression of HsCEN1 homogene is present during early embryonic development including two-cell stage,multicell stage,gastrula to trochophora.

我们还用RT-PCR方法检测了Centrin同源基因在单环刺螠精子分化过程和早期胚胎发育过程的表达，结果显示：在单环刺螠精子发生过程中的精细胞、精子团、精子中都有表达，而在成体的体壁组织、消化道组织、体腔球中则没有表达；在未受精卵中没有表达，而在受精后释放极体的受精卵和经A23187孤雌激活的卵中则有表达；在单环刺螠的早期发育过程——二细胞胚胎、多细胞胚胎、原肠胚、早期担轮幼虫——中都有表达。

Paclobutrazol and Unlconazole inhibited the cell elongation and cell division, plant nutrient transportion and the growth of other parts of the plant, which were the main reasons of the Coleus blumei dwarfing.

多效唑和烯效唑对其细胞伸长和分裂有抑制作用，限制了筛管营养物质的运输，抑制了植株其他部位的生长，这些是使彩叶草株型矮化的主要原因。

Gas diffusion layer is one of the most important components in proton exchange membrane fuel cell. The contact resistance between current collector and gas diffusion layer is an important part of the total resistance of fuel cell and is also a key factor led to the power loss of PEMFC.

气体扩散层是质子交换膜燃料电池的重要组件，其与极板之间的接触电阻是燃料电池内阻的重要组成部分，也是导致燃料电池功率损失的重要因素。

The number of vascular bundles, the number of vessels with secondary cell wall in the vascular bundles and the cell wall thickness of collenchyma all increased in BBC.

一、利用光镜切片、电镜切片和扫描等方法，对"花打顶"后黄瓜的叶片、茎和茎尖等部位的形态、解剖和细胞学特征进行了分析后发现： 1。

Six parameters were determined,i.e.,cell layers of collenchyma and parenchyma,cell wall thickness of collenchyma,thickness of cortex layer and vascular bundle,and diameter of vessel lumen.

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.
