受精卵

Following implantation of the fertilised egg menstruation should not occur , hence for women who have been sexually active and who have previously menstruated regularly , the absence of a period should be put down to pregnancy .

以下植入的受精卵月经不应该发生，因此，为妇女谁已性行为活跃的，谁先前已menstruated定期，没有一个时期，应放下怀孕。

The results show that when the PHMB is≤16×10^(-6)μl/L, the hatching rate of zygote is no affected; when the PHMB is≤4×10^(-6)μl/L, the metamorphosing rate of nauplii is no affected.

结果显示，用PHMB对中国对虾受精卵消毒，其对孵化率无显著影响(P.05)的浓度为≤16×10^(-6)μl/L；用PHMB对中国对虾无节幼体消毒，对变态率无显著影响(P.05)的浓度为≤4×10^(-6)μl/L；并且其药效保持时间较长。

With the increase of the 1254 dosages, in the further development process of 2-cell embryo, there still occurred the development relayed and degeneration, so that the development rate of morulae and blastocysts decreascd significantly.

在受精卵的进一步发育中，随著公鼠染毒剂量的增加，发育到桑椹胚和囊胚的比例显著降低，发育延迟胚及发育中退化变性胚比率显著升高。

Therefore, we suggest that the zygote and nauplii of Fenneropenaeus chinensis was disinfected with (2~3)×10^(-6)μl/L of PHMB.

根据本试验的结果，使用(2~3)×10^(-6)μl/L的PHMB对中国对虾受精卵和无节幼体进行消毒处理是有效可行的。

Owing to placenta and milk transshipping effect, the content of Aroclor 1254 in fetal and infant vivo was very low, so there were not significantly pathological changes in sexual gland, the effect of Aroclor

2首次以排卵数、受精率、受精卵的第一次卵裂率、桑堪胚发育率、囊胚~孵化胚发育率、以及发育延迟胚和退化变性胚的比率，对个体发育的不同时期接触不同剂量 AroClor 1254对小鼠卵子发生、受精和附植前胚胎体内发育毒性进行系统定量。

These help to anchor it to the lining of the uterus and will eventually grow into the placenta, the organ that feeds and protects the baby until birth.

之间的5和后七天内排卵，受精卵植入到墙壁的子宫和产生的根源一样outgrowths所谓的绒毛，这些帮助锚，它向衬砌子宫，并最终将成长为胎盘，机关，饲料和保护，直到婴儿出生。

Cell resulting from cleavage of a fertilized ovum.

受精卵分裂形成的细胞。

Rabbit zygotes were cultured in sequence culture system that contains: R1 culture medium which is with low concentration of glucose (1.0 mmol/L) and then R2 culture medium which is with high concentration of glucose (3.5 mmol/L).

试验采用含低浓度葡萄糖(1.0mmol/L)的R1培养液和含高浓度葡萄糖(3.5mmol/L)的R2培养液对兔原核期受精卵进行了体外序贯培养，并与传统的RID单一培养进行比较，研究了兔早期胚胎在体外序贯培养系统中的发育效果。

Those parent abalones of wild or artificial selection with good economic characters must be chosen in order to avoid close breeding.. Correct breeding techniques must be adopted to obtain excellent germ cells and larvae. The survival rate and disease resistance of juvenile abalone can be remarkably increasedonce the further selecting and culturing are carried out. The rejuvenation is realized once a good breeding condition for the young and parent abalones is created, the adverse culturing condition and technical maloperation are reduced or eliminated. The survival rate of the breeding and young abalonesincrease about 28.9%-31.2%, the survival rate of the grown abalones is high up to 85%-90%.

通过挑选经济性状好的台湾九孔鲍和人工选育的九孔鲍亲体进行繁殖，避免近亲繁殖，选优除劣，达到正本清源的目的；采用正确的繁殖技术，获得优良的受精卵和幼虫，通过对幼虫进一步选优和培育，使附板后的幼鲍成活率及抗病力得到明显提高；为九孔鲍的苗种和亲本培育创造良好的养殖生态条件，减少和消除了不利的养殖环境和操作技术，达到品种复壮的目的；阐述了野生鲍、复壮鲍、退化鲍三个不同类群的免疫机能具有显著的差异，复壮后的九孔鲍，其免疫机能基本达到了野生鲍的水平；人工育苗和幼鲍的成活率提高了28.9%-31.2%；成鲍的养殖成活率高达85%-90%以上。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
