查询词典 sperm oil

Some handles may turn off genes in sperm and egg cells . The genes then remain shut off after a sperm fertilizes an egg .

一些处理可能关闭精子和卵子的基因，这些基因在精子使卵子受精后一直处于关闭状态。

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。

The invention provides the technology used for identifying the bull X and Y sperm separation purity with low cost and simple, rapid, and accurate operation, and provides reliable technical support for the popularization and the application of the subsequent sexing semen and the optimization of a sperm separation method.

本发明提供了一种成本低廉，操作简便、快速、准确的鉴定牛X、Y精子分离纯度的技术，为后续性控精液的推广应用及精子分离方法的优化提供一个可靠的技术支持。

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。

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。
