In addition, some biological events, such as separating the male germ unit, providing movement orbits for the two sperm cells and inducing both sperm to synthesis DNA, may also be related to the degenerated synergid.

This review introduced the study of cell cycle of male and female gametes before fertilization; discussed the question of synergid degeneration; analysed status of research into the movement of both sperm cells in degenerated synergid; and evaluated the preferential fertilization of sperm cells and the egg cell activation of angiosperms.

本文介绍了目前被子植物精、卵细胞融合前后的细胞周期变化、退化助细胞的功能、精细胞在退化助细胞中迁移的研究动态、精细胞的倾向受精和卵细胞的激活等被子植物受精生物学领域中的一些新的研究成果和发展趋势。

It takes about 0.5 h for a pollen tube from germination to arrive at the micropyle. About 0.5 h after pollination, the pollen tube releases two sperms into one synergid. At 0.5-2.5 h after pollination, the egg cell fuses with one sperm to form a zygote. About 10.0 h after pollination, the division of the zygote begins. The duration of the zygote lasts about 2.5-10.0 h. However, one sperm nucleus fuses with two polar nuclei at 1.0-3.0 h after pollination, and 5.0 h after pollination the primary endosperm nucleus begins to divide.

水稻受精过程经历的时间表如下：授粉后，花粉在柱头萌发；花粉萌发至花粉管进入珠孔大约需要0.5小时；授粉后0.5小时左右，花粉管进入一个助细胞，释放精子；授粉后0.5-2.5小时，精卵融合形成合子；授粉后约10.0小时，合子第1次分裂，合子期为授粉后2.5-10.0小时；授粉后1.0-3.0小时，精核与两极核融合；授粉后约5.0小时，初生胚乳核分裂。

We think that centrin play an important role in meiosis during Urechis unicinctus sperm metamorphosis difference and we also think that centrin may be related to trochophore cilia and sperm tail formation,and reconstraction of centrosome after fertilization.

我们推测Centrin在单环刺螠精子发生过程中减数分裂或精子细胞变态分化过程中发挥作用；在单环刺螠早期胚胎发育中，Centrin可能与受精后中心体的重建及担轮幼虫的纤毛形成有关。

The sperm can be stored in the sperm storaged tubule which lies in the uterovaginal junction more than 24 days.

精子在黄腹角雉雌体内的贮存时间可以达到20天以上。

The fertilizing rate of turbot sperm after being stored for 3 h was similar to that of fresh sperm.

本实验保存大菱鲆精子的方法完全满足了大菱鲆精子短距离运输的要求。

Wapiti sperm capacitation in vitro and its ultrastructural change were studied in order to choose a set of perfect and feasible protocol of wapiti sperm capacitation in vitro, and to provide a basis data on the research of wapiti capatitation in vitro and the mechanism of fertilization.

本研究以马鹿为试验对象，开展了对鹿精子体外获能以及获能前后精子超微结构变化的研究，以期筛选出在实践中具有可操作性且效果良好的马鹿精子获能培养体系，从而为鹿体外受精和受精机理的研究奠定基础。

Ultimately 7 out of the 7 calves produced by wapiti hinds inseminated with Y-sorted sperm were male (100%) and 8/8 calves or 100% of the calves from hinds inseminated with X-sorted sperm were female.

本研究旨在将精子专用高速的流式细胞分选技术用于梅花鹿、马鹿和山羊，初步建立了梅花鹿、马鹿和山羊分选精液的低剂量授精技术体系和进一步对高纯度分选奶牛精液采用扣除杂交筛选，初步获得牛XY精子间的差异表达基因。

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。
