卵子

These results provide a new proof of AR participating in the regulation of oogenesis development. 4. The immediate early-gene c-fos palys an important role in cell multiplication and differentiation.

这是我们首次在白蚁卵子发生过程中发现AR，并对非繁殖蚁和繁殖蚁生殖细胞发育的激素调节进行了对比，为进一步探讨AR在昆虫卵子发生中的调节机制提供了依据。

The oogenesis of P. esculenta can be divided into the following phases in morphological characteristics of oogonium and oocyte development: the proliferative phase of oogonium (0μm in diameter), the initial growth phase of oocyte (10—20μm in diameter), the grand growth phase-Ⅰof oocyte (20—60μm in diameter), the grand growth phase-II of oocyte (60μm×70μm to 120μm×145μm in size), the mature phase of oocyte, and the declining phase, showing a dynamic changes in oogenesis of P. esculenta .

以卵原细胞与卵母细胞发育的形态学特征为依据，将可口革囊星虫的卵子发生过程划分为：卵原细胞增殖期(卵径0μm)、卵母细胞小生长期(卵径10—20μm)、卵母细胞大生长期Ⅰ(卵径20—60μm)、卵母细胞大生长期Ⅱ[大小为(60μm×70μm)—(120μm×145μm)]、卵母细胞成熟期及退化期6 个阶段，反映了可口革囊星虫卵子发生过程的动态变化。

Parthenogenesis in which the egg is activated by sperm ,but without fusion of the egg and sperm nuclei.

雌核生殖一种单性生殖，精子激活卵子，但是卵子和精子核没有融合

PATTERN OF SINISTRAL EGGS, BUT AN INJECTION FROM SINISTRAL EGGS DOES NOT

卵子的细胞质进行的注射却不能影响到右旋卵子。

The process inoles creating an animal not from egg and sperm but by placing the nucleus of a cell inside an egg that's had its nucleus remoed.

一个生命体本来是从卵子和精子的结合开始的，但是克隆技术是将一个细胞的细胞核放置到一个去细胞核的卵子中。

Once within the egg wall, the sperm's nucleus is drawn toward the egg's. The two cells gradually and gracefully become one.

精子进入了卵子后，它的细胞核就会向卵子的细胞核移动，慢慢结合为一个，而两个细胞也变成一个细胞，这个过程叫做受精。

Once within the egg wall, the sperm's nucleus is drawn toward theegg's. The two cells gradually and gracefully become one.

精子进入了卵子后，它的细胞核就会向卵子的细胞核移动，慢慢结合为一个，而两个细胞也变成一个细胞，这个过程叫做受精。

Our results confirm, for us, that the best way to do the experiments is with unfertilized oocytes.

我们的结果证实最好的实验工具是用未受精卵子，但卵子的取得并不是那么容易的事情。

That's far too many if one hopes to use human unfertilized eggs, which are cumbersome to obtain from women.

如果有人希望使用人类的未受精卵产生干细胞，那么这需要的卵子实在太多了。如果这些卵子从妇女身上获取那么将会非常的繁重。

The egg is coated with the zona pellicuda, a glycoprotein that protects the egg but also helps to trap and bind sperm.

这个卵子的透明带状物pellicuda ，一种糖蛋白，它既保护卵子，而且还有助于诱惑和限制精子结合。

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。
