卵裂的

There were 8 embryos single blastomere amplified, and the amplification success rate was 72. 7%(8/11); 3 embryos' not amplified; 2 embryos'showed preferential amplification , and the PA rate was 25%(2/8); and the 7 tubes of blank with washing cell solution were not contaminated. We transferred 3 unaffected embryos to the uterus. But unfortunately, blood hCG was negative after 2 weeks of transferring indicating no pregnancy.

共8枚胚胎的单卵裂球得到扩增，扩增成功率为72.7%（8/11），3枚未得到扩增，2枚发生了偏性扩增(preferentialamplification，PA)，PA的发生率为25%（2/8），细胞洗脱液空白对照7管均无污染发生。3枚诊断为正常的胚胎被移植入宫内，不幸的是，移植后2周，血hCG阴性，证明未妊娠。

Fruit indehiscent nutletlike silicle, often breaking into 1-seeded units, oblong, ovoid, or ellipsoid, 1-loculed or transversely 2- or 3-loculed, terete or 4-angled, sessile, woody, often prominently veined, glabrous or papillate, smooth or torulose, sometimes verrucose-reticulate; replum rounded; septum absent; style absent, obsolete, or distinct, thickened and subconical; stigma capitate, entire.

果不裂的坚果状的短角果，通常插入1种子单位，长圆形，卵球形，或椭圆形，横向室2或3的1室或，假隔膜绕行；隔膜无；花柱无，淘汰，或者离生，加厚和近锥形；柱头头状，全缘。

It indicated that the yield of tetraploidy not more than 25% induced by inhibiting the first mitosis with CB, colchicine and 6-DMAP, respectively, while it can be induced with higher percentage by blocking PB1releasing with CB. The tetraploidy percentage of groups shock began at 15—22min after fertilization are higher than that shock began at 42min, and the yield of tetraploidy also increased with the CB density and time lasting.

结果表明，CB、6-DMAP和秋水仙素抑制扇贝第一次卵裂诱发四倍体的比例低于25%；采用CB抑制PB1可有效地诱导产生四倍体，从授精后42min提前到15—22min开始处理，抑制PB1的放出有助于提高四倍体的比例，在12℃，处理开始和终止时间分别在授精后20—22min和62—67min时(即PB2始出现时)，面盘幼虫四倍体率最高，为56.5%。

The development speed of gynogenetic embryos was later than that of the control group, and aneuploids were found in this study. The obvious improved survival of trochophore larvae with a peak at 40s UV exposure suggested the presence of a Hertwig effect in the gynogenesis of A. pectinata. When sperms were irradiated for 40s, the cleavage rate was relatively high (51.2%), the developmental rate of D-larvae became zero, and the rate of haploid reached the highest (36.8%).

经紫外线照射的精子受精后所产生的单倍体胚胎发育速度慢于正常受精所产生的二倍体胚胎，各照射组均出现非整倍体。40s照射组中卵裂率达到51.2%，D型幼虫发生率为0，单倍体率最高，达到36.8%，出现"Hertwig效应"。

This site provides image materials on fish development, including time-lapse recordings illustrate the morphogenesis of zebrafish embryos, from early cleavage to organ rudiment formation, fish epidermal cell movies, 3-D films of zebrafish gastrulation, and much more.

该网站提供有关鱼类发育的图像材料，包括阐明斑马鱼胚胎形态发生（从早期卵裂到器官初期形成）的时间间隔录象、鱼类表皮细胞影片、斑马鱼原肠胚形成的三维影片，等等。

Completion of the synthesis involved displacement of the remaining alcohol through a three-step, telescoped sequence featuring an efficient cleavage of an aryl mesylate, and a practical method for introduction of the isobutyric acid fragment.

完成剩余的位移所涉及合成酒精通过三个步骤不胜顺序展出了高效率的卵裂甲磺酸芳、而实际的方法引入异丁酸片段。

Keel lamellate, with 3-lobed apical appendage; petals connate in lower 3/4; leaf blade ovate-, obovate-, or elliptic-lanceolate, 3.5-8 × 1.5-2.5 cm, abaxially dark purple, base oblique.

龙骨状片状，具3浅裂的顶端附属物；花瓣合生的在下部3/4；叶片卵形-，倒卵形-，或椭圆形披针形， 3.5-8 * 1.5-2.5 厘米，背面的深紫色，基部偏斜。

Then we compared cleavage rate and blastocyst rate among different groups. After that we evaluated the quality of blastocysts by using ICM/TE (Inner cell mass/Trophectoderm cells) ratio via staining with propidium iodide and Hoechest333258, and analyzed the level of genome methylation and histone acetylation by immunofluorescence.

比较各组受精卵的卵裂率和囊胚发育率；并应用碘化丙啶和Hoechest333258对囊胚进行染色，利用ICM/TE值评价各组胚胎体外发育的质量；同时将囊胚进行免疫荧光染色，观察其基因组甲基化和组蛋白乙酰化的水平。

Herbs aquatic; at least female flowers lacking petals or inconspicuous; fruit splitting at maturity into (2-)4 1-seeded mericarps; leaves whorled, at least the lower ones pinnately divided.

肾形，卵形的叶，或正三角形；四棱形的果圆柱状或，裂爿先端容易与分离在开裂的假隔膜；子叶现任。 2 Myriophyllum 狐尾藻属

By three days after injection, the number of embryos which had cleaved to the 2-cell stage was 0 with round spermatids and mree(17.6%) with elongated spermatids.

结果在培养的 3 d中，ROSI的卵子没有发生卵裂，＆ ELSI的卵子中有 3个服至 2细胞期O7.6O）。

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。
