查询词典 sperm receptor

GIFT is again the removal of the oocyte from the ovary, but instead of fertilization outside the body, the egg and sperm are mixed together, placed into the fallopian tube, where fertilization and embryo development take place (this is where the sperm and egg normally meet).

GIFT也是从卵巢取出卵母细胞，但是并不是在体外进行受精，而是将卵和精子混合在一起，送回到输卵管，受精和胚胎发育是在那里进行的（这就是正常情况下卵和精子相遇的地方）。

Comparative analyses of sperm structures among the tailed amphibians indicates that: the feature evolution of sperm in urodeles is related to the differentiation of their fertilization modes

此外，与已有报道的有尾两栖类物种精子的结构特征进行分析比较表明：有尾类精子特征的分化与其受精方式的变化是一致的

Epidemiologist Luc Smits of Maastricht University, the Netherlands, who led the study, believes the results support the idea that sperm bearing the male Y chromosome swim faster than sperm with the female X chromosome, and can travel through viscous cervical mucus more easily.

荷兰Maastricht大学的流行病学家Luc Smits领导了这项研究，他相信这项结果支持携带Y染色体的精子游的速度要快于携带X染色体的，且更容易穿过粘性子宫颈粘液的想法。

Most sperm nuclei eventually developed into the male pronuclei, just like the normal sperms, except sperm nuclei in a few zygotes kept dense throughout the fertilization process. Dense chromosome body was seen at the nuclear area during the prophase of first mitosis, and in the middle of spindle at metaphase of first mitosis.

精子入卵后形成精核，大多能够逐渐解凝、液化并膨大，最终形成形态正常的雄性原核，但在第一次卵裂早期退化成浓缩的染色质小体，并在胞质分裂时随机地分配到其中一个子细胞里的分裂沟附近。

He spins a special web, expels sperm onto it, then sucks the sperm into bulbs on the ends of his pedipalps

它会织出一个特殊的网，将精液排在上面，然后把精液吸附在须肢末端的球状物上。

He spins a special web , expels sperm onto it , then sucks the sperm into bulbs on the ends of his pedipalps .

译文蛛丝出自于蜘蛛的腺体，这些腺体构成了蜘蛛腹部的很大一部分。

Because the long chained fatty acids are better oxidised, the sperm cell will have higher energy content and thus the motility of the sperm will increase.

由于长链脂肪酸的利用率提高，精细胞将获得更高的能量，使其活力增强。

MATERIAL AND METHODS: Thirty 30 healthy Sprague- Dawley adult male rats were randomly divided into 3 groups: control, alcohol 7.5 g/kg and alcohol 7.5 g/kg ＋ vitamin A 50 μ g/kg. Alcohol and vitamin A were administrated to the rats for 13 weeks by a gastric tube. The sperm counting ,motility and the percentage of abnormal sperm were observed. Serum testosterone was determined. The patholgical changes of testicle tissue of rats were observed by light and electron microscopy.

材料与方法： 30只健康雄性成年 SD 大鼠随机分为对照组、酒精组、酒精＋ VA 组，各组每日分别灌胃给予酒精0、7.5 g/kg 、酒精7.5 g/kg ＋ VA 50 μ g/kg ，连续13周后对各组大鼠的精子计数、精子活动率、精子畸形率、血清睾酮(Serum testosterone，T )进行检测，光、电镜观察睾丸生精上皮的组织学改变。

Sperm antibody test to check for protein molecules that may stop sperm fertilising an egg.

精子抗体测试，以检查蛋白分子可能会停止精子fertilising一个鸡蛋。

They are the result of two sperm cells fertilising a single egg, which then divided to form two embryos - and each sperm contributed genes to each child.

他们是两个精子细胞与一个卵子结合的结果，结合后的卵子分裂形成了2个胚胎——各自精子对各自幼儿提供基因。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
