卵裂的

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。

结果］洞庭黄鲶的胚胎发育过程可分为胚盘期、卵裂期、囊胚期、原肠期、神经胚期、器官形成期和出膜期7个阶段。

Single blastomere PCR is stable and reliable,and it can be used for preimplantation genetic diagnosis.

目的建立单卵裂球PCR技术，为开展单基因病的着床前遗传学诊断奠定基础。

FISH technique could be performed for the detection of HBV in human blastomere cells,and it has great significance to reduce vertical transmission of HBV in IVF-ET.

荧光原位杂交技术可用于卵裂球细胞HBV感染的检测，在体外受精-胚胎移植实践中对降低HBV垂直传播有重要意义。

The cells of blastomere randomly distributed either embryonic parts or extraembryonic parts of blastocyst.

2-细胞胚胎卵裂球随机分布在囊胚的胚胎部分和胚外部分。

Blastomere numbers and morphology scores were highest in group Ⅰ(P.05), but no significant differences existed between group Ⅱ and group Ⅲ.

组的胚胎卵裂球数目及胚胎形态评分均显著优于Ⅱ组及Ⅲ组(P.05)；Ⅱ组与Ⅲ组相比差异无统计学意义。

F508 mutation detection on the single blastomere was performed with nested polymerase chain reaction.

同时利用套式聚合酶链反应技术，对活检所得的单个卵裂球分别进行ΔF508 突变基因检测。

开裂的果长角果或短角果，线形，长圆形，卵球形，，或椭圆形，具宽隔膜的圆柱状或，无梗或具短柄；裂爿具一离生中脉，滤波或；假隔膜绕行；隔膜完全，膜，半透明；对2.5毫米废退，宿存的花柱；柱头头状，2裂的全缘或很少，单列的种子，无翅，长圆形，肥厚；网状，不黏的种皮被弄湿；子叶现任。

Basal leaves lanceolate or nearly lanceolate, 2-5 cm wide, margin crisped or strongly undulate, base cuneate; valves broadly ovate to ovate-triangular, base nearly truncate.

基生叶披针形的或近披针形的，2-5厘米宽，边缘皱波状的或强烈波状的，基部楔形；裂爿宽卵形的到卵形三角形，基部近截形。

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.

交际能力和语法的关系应该是目标与途径的关系。
