可受精的

Egg selection enables only the healthiest eggs to be taken from the ovaries for fertilisation. It can be useful for women with diminished number and quality of eggs.

蛋的选择，使只有最健康的卵子将要采取的从卵巢为受精，它可用于妇女与减少的数量和质量的鸡蛋。

Using RT-PCR analysis, RGS7 was expressed from fertilization to 96 hours post-fertilization of Zebrafish. Expression of RGS7 was found in brain、aorta ventralis、intermediate cell mass and somite by whole-mount in situ hybridization.

因此，利用RT-PCR以及全胚体原位杂合技术，结果发现在受精后0~96小时的斑马鱼胚胎中皆可侦测到RGS7的表现，其表现的位置是在斑马鱼胚胎的脑部、腹侧主动脉、中期细胞团及体节等组织部位。

Pem gene is expressed in a time and stage specific manner. Pem transcripts are detectable as early as day 6 in mouse embryonic development, and are abundant in day 7 and 8, but decrease precipitously thereafter. Although Pem transcripts are not detectable in most of adult tissues, they are present in reproductive system. Furthermore, Pem has also shown to be specifically expressed in the proximal cauda and distal corpus regions of the epididymis, the regions where spermatozoa gain forward motility and fertilization competence.

Pem基因的表达具有明显的时间和空间特异性：在鼠胚发育的第6天，即可检测到Pem转录本的表达；第7-8天，Pem表达量达到最高，随后迅速减少；Pem基因在成年组织中一般不表达，但可在生殖组织表达；另外，Pem特异地在附睾近侧尾部和远侧的体部中表达，此处是精子获得运动性和受精能力的地方。

In the developed world there are a number of options: a process called 'sperm washing', which separates sperm from HIV-causing agents before being used for insemination, is safest for couples where a positive man wants to avoid the risk of infecting his negative female partner or reinfecting his positive partner; artificial insemination is the safest way of conceiving for couples with a positive woman and a negative man.

在发达国家他们会有许多选择：&精子洗涤&，即在受精前将精子与引起HIV的物质分离，这样可使阳性的男性避免传染阴性的女伴，或再传染给阳性配偶，对于这种情况，&清洗精子&是最安全的；人工授精，这对于由阳性女伴和阴性男伴组成的夫妇来说是最安全的生育方式。

4H was the best time of bovine oocyte activationin the 6-DAMP, and the cleavage rates and blastula rates could reach 85.1% and 26.8%. 4. IVF-100 was used in vitro fertilization, because IVF-100 was not needed to prepare usually,store conveniently, and gain a higher cleavage rates. After the oocytes have matured for 20h, theywere digested by permease and treated with suctionpipe.

由于IVF-100无需经常配制、保存方便且可以获得较高的卵裂率，所以本实验采用IVF-100为受精液，卵母细胞成熟20小时后采用透酶+口吸管消化的方法处理，获得了较好的受精效果，卵裂率可达(76.8％)。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
