目的 探讨抗精子抗体与抗子宫内膜抗体在不孕、流产中的作用及二者关系，进一步揭示不孕、流产的病因。

Histological characteristics of reproductive gland,were described and its relations to the cantharidin stored and transferred within or between the adults were discussed. Epicauta mannerheimi ; Mylabris phalerata ; reproductive gland ; histological characteristics ; cantharidin

作者在进行两种芫菁生殖腺解剖后，又初步探究大斑芫菁生殖腺的组织学特征，目的在于为芫菁的精子贮存、运送、授精、芫菁素传递等过程提供初步理论依据。1 材料和方法1 。1 材料细纹豆芫菁于 1 999年 6月中旬采自福州市郊高

This suggests that the secreted epididymal proteins are transferred to spermatozoa by an unusual mechanism.

这表明附睾来源的分泌蛋白通过不同寻常的机制转移到精子上。

Mammalian spermatozoa go through the process of epididymal maturation to develop their capacity for fertilization.

随着精子在附睾中的转运，它们与卵子质膜的融合能力逐渐增加。

These methods place the sperm near the mouth of the Fallopian tubes and ovaries.

这些方法的地方，精子河口附近的输卵管和卵巢。

Since the discovery of their flagellated spermatozoids by Hirase and Ikeno, the general mor- phology and anatomy,the life cycle and the systematic evolution of Ginkgo and cycads have been described in many reports.

自1896年Hirase和Ikeno分别发现银杏和苏铁类植物的游动精子以来，研究人员对它们的生活史、胚胎发育、系统演化等已进行了大量研究。

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。

In this study, isoelectric focusing electrophoresis program was optimized, and various sample preparation methods, different loading quantities and strip length were studied.

在实验中，优化了等电聚焦程序，研究了精子蛋白的不同制备方法、不同上样量、不同胶条长度对电泳结果的影响。

抗精子抗体具有体外杀精作用，但同时也有轻度、可接受的阴道刺激性，作为外用避孕药是可行的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
