The adjustment mechanism of the follicular development is very complex. The influence of ovarian local factors and the influence from follicle itself were mainly discussed. During the oogenesis, many ultra microstructure changed.

卵泡发生的调节机制非常复杂，在此重点研究卵巢局部因子对卵母细胞发育的影响以及卵泡各结构间的相互影响，卵母细胞发育的过程中也出现了超微结构的改变。

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。

So it is important to study the mechanism of oocyte aging. Herein, we studied the change of oocyte chromosome after ovulation into the oviduct in vivo.

这种卵母细胞的老化会导致包括人在内的哺乳动物的胚胎发育异常，所以很有必要研究排卵后卵母细胞的老化机理。

The paper systematically studied the effect of time of maturation in vitro, duration of 6-DMAP treatment and culture medium system on development of parthenogenetic ovine embryos.

系统地研究了绵羊卵母细胞成熟培养时间、6-DMAP激活时间以及改进的培养液对绵羊卵母细胞孤雌发育的影响。

During the manufacturing of the critical intermediate cephalosporin nucleus --7-amino-3-chloro-cephalosporanic acid diphenylmethyl ester hydrochloride salt, first the feasibility of the one-pot synthetic route of open loop, closed loop and ozonization when chlorine is passed over is qualified by experiments. Then the critical factors that will influence this reaction are studied as follows: the mol ratio of triphenyl phosphite and Diphenylmethyl 3-hydroxy-7-phenylacetaminoceph-3-em-4-carboxylate-l-oxide is four to one; the quantity of the stablizer should be at least more than two to one. The temperature of the system must be 25℃ when chlorine is passed over so that the hydrochloride can be precipitated to obtain cephalosporin nucleus of cefaclor--7-amino-3-chloro-cephalosporanic acid diphenylmethyl ester hydrochloride salt.

在制备关键中间体头孢母核7-氨基-3-氯头孢烷酸二苯甲酯盐酸盐时，先通过实验验证把开环、闭环、臭氧化三步在通入氯气时并为一锅煮的合成路线的可行性之外，又研究了影响该反应的几个重要因素：亚磷酸三苯酯与3-羟基-7-头孢烷-5-亚砜-2-甲酸二苯甲酯的摩尔比为4：1；稳定剂2-甲基-2-丁烯的用量至少大于2：1，通入氯化氢气体时体系温度在25℃时盐酸盐则能够顺利析出，获得头孢克洛的头孢母核—7-氨基-3-氯头孢烷酸二苯甲酯盐酸盐。

Film director in the performance of this scene, there was no way the main characters using Close all, but to parents, children and lioness with a panoramic camera at the same time, maintaining the child, lioness and the parents that among the three the true spatial relationship.

影片的导演在表现这个场面时，没有采用近摄各个主要人物的手法，而是把父母亲、孩子和母狮同时摄在同一个全景中，保持孩子、母狮和孩子的父母这三者间的真实的空间关系。

Jiangsu Academy of Agricultural Sciences, Nanjing 210014, China on artificial activation and parthenogenesis in mammalian oocytes are reviewed, in-cluding oocyte activation and

综述了哺乳动物卵人工激活与孤雌生殖研究的主要进展，包括卵母细胞的激活与孤雌发育，父源和母源基因组在胚胎发育中的作用，以及孤雌生殖小鼠的诞生。

IGF2, which encodes a protein functioning as a fetal growth factor and a cell mitogen, is expressed only from paternally allele in most tissues but from both alleles in adult liver. H1 9, which acts as an RNA, is a gene of unknown function and expressed only from maternally allele.

IGF2编码的胰岛素样生长因子-2是一种胚胎生长因子及细胞有丝分裂原，在人体内大多数组织中特异地表达父系来源的等位基因，而母源等位基因处于印记状态。H19表达一种功能尚不清楚的RNA，其印记状态与IGF2相反，目前发现H19在正常组织内均为母源等位基因表达，父源等位基因印记。

In the paper, author combines the Western Folklore Motif and China Confucian culture, starting with patricide imago literature, to probe into Patricide Motif in the movie.

本文引入西方民间文学的母题概念，结合中国儒家文化的"家国"思想，从文学中"弑父"意象的分析入手，提炼出电影中的"弑父"母题作为研究对象。

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.""
