查询词典 sperm sac

Histological observation showed that there were no significant differences in the gonad development cycle between hybrids and S. intermedius, and during the whole development period of gonad, only the ovary can produce few mature ovary cells and the mature sperm were not found in testis.

杂交海胆在生殖腺发育的整个过程中，生殖腺指数虽然也出现周期性的变化，但组织切片观察发现杂交海胆生殖腺发育不能象母本一样有明显分期，只有个别雌性个体能产生成熟卵细胞，雄性个体未见成熟精子。

Sperm may be placed in the neck of the womb, known as intracervical insemination, or inside the womb itself, known as intrauterine insemination.

精子可摆放在颈部子宫，称为intracervical人工授精，或子宫内的本身，被称为宫腔内人工授精。

There is a significantly difference between the tubular widthes of obstructive and non-obstructive azoospermic patients. The large number of intratubular germ cells within those tubules with active spermatogenesis cause those tubules to be larger than tubules without sperm production.

而藉由测量细精小管，我们得知造精功能受损患者的细精小管管径明显地较具正常造精功能的细精小管细，原因为造精作用活跃的细精小管内生殖细胞较多，因而造成有精子生成的细精小管管径明显的较没有精子生成的细精小管粗。

Gestational and lactational exposure to endosulfan did not show any demasculinizing or feminizing effect in rats, and sperm production and fertility of the male offspring were not affected.

大鼠孕期和哺乳期经口接触硫丹，没有引起雄性子代的雌性化，也不影响雄性子鼠的生精功能和生育力。

抹香鲸- Physeter鲷（平均体重：15-40吨，总长度：10？15米

The mammiferous testis perform important functions of producing sperm and secreting male hormone.

雄性哺乳动物的睾丸具有生精和分泌雄性激素等重要的功能。

The sperm must not have undergone meiotic division...

精液不能已经遭遇减数分裂的区分。。。

The results are as follows:(1)in testis tissue, the expression of RB gene only was found in spermatocytes and prespermatids of seminiferous tubule of immature mice and spermatids of mature mice, and it was not found in the spermatogonia, spermatognial stem cell and primary metamorphous sperm from both immature and mature mice.

这些结果表明，RB基因在小鼠精子和卵子的发生过程中有着重要作用

Following the accepted Eckstein meteyard,the effect score of anti-sperm ant...

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。
