受精卵

A independent life individuality is finally formated from singlecell ferti1ized egg throngh egg cleavage、morula stage、blastocoele stage、protogaster stage and orange etc, and concerned in major basal questions of development and gene expression.

单细胞的受精卵通过卵裂、桑椹胚、囊胚、原肠胚及器官的发生等，最后形成一个能独立生活的个体，涉及发育和基因表达的许多基本问题。

Ontogenesis begins from the fertilized embryo. After the cells proliferation during the embryo cleavage, it enters the stage of blastoderm differentiation、 tissue and organ formation.

个体发育从受精卵开始，经过卵裂阶段的细胞增殖后，进入到胚层分化、组织和器官形成阶段。

The egg consists of an outer casing, or chorion, inside which is the female's fertilized ovum.

鸡蛋构成的外壳，或绒毛内，这是女性的受精卵。

"For many years, the aging of gametes as a result of prolonged retention in the female reproductive tract before fertilization has been circumstantially associated with major birth defects," write Joe Leigh Simpson, MD, and colleagues from Baylor College of Medicine in Houston.

休士顿Baylor医科大学的Joe Leigh Simpson医师，和他的同事们写道：「许多年来，由于在受精前，雌配子在女性生殖管道中的滞留时间过长，所导致的受精卵的老化，被很偶然的认为与主要出生缺陷的发生有关。

To obtain the fertilized eggs with clear male pronuclei is the key of success .

显微注射法是制备转基因动物的首选方法，而原核清晰受精卵的获得是影响显微注射成败的关键。

The layer of gelatinous material that separates the inner and outer cell layers of a coelenterate.

胚盘由哺乳动物受精卵分裂而形成的细胞层。后期分裂为三层，胚胎由此发育

Although the ability to reprogramming of Kun Ming white mouse oocytes cytoplast is not effectively, reprogramming ability has improved when cystoplasts from oocytes and embryos work together.

昆明白小鼠卵母细胞胞质对体细胞核的重新编程能力较弱，而当其与正常受精卵的胞质共同作用时可较好地改善对体细胞的重新编程能力。

The snail was found to have an indirect developmental type in the early development. The fertilized eggs were oval-shaped and discoidal cleavage. Embryonic development stages were divided into cleavage, blastula, gastrulae, trochophore, and intra-membrane veliger. Larval development stages included veliger, late veliger and crawling larvae metamorphosed to juvenile.

结果表明：黄口荔枝螺卵囊高度平均为7.33 mm，卵粒数量平均为165粒；黄口荔枝螺的早期发育属间接发生型，受精卵呈椭圆形，卵裂为盘状卵裂；在卵囊内，胚胎发育包括卵裂期、囊胚期、原肠胚、膜内担轮幼虫、膜内面盘幼虫；幼虫发育包括面盘幼虫、后期面盘幼虫和匍匐幼虫。

High culturing temperature results in short interval between fertilization and eclosion, whereas more days are required at low temperature. The culturing temperature has a significant influence upon the numbers of P.

在连续60天的观察中，发现同一天的受精卵，在实验室中有两个羽化高峰，间隔呈现似半月周期的现象，两峰的间隔会受全期平均温度的影响，高温两峰的间隔短，低温则较长。

Objective: To investigate the effect of protein kinase B on the regulation of mouse early embryo development.

目的：研究蛋白激酶B的活性变化对小鼠受精卵早期发育的影响。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
