细胞分裂

One secondary spermatocyte divides and eventually grows into two sperm cells.

一个次级精母细胞分裂并最终产生两个精子。

Spermatogenesis is a continuum of cellular differentiation in which three principal phases can be discerned: spermatogonia renewal and proliferation, meiosis and spermiogenesis.

睾丸的精子发生是一个独特复杂的细胞分裂分化过程。

At the start of cell division, fibrils appear to radiate from the centrioles, forming starlike ASTERS.

在细胞分裂开始时，从中心粒发出星状的纤维，即星体。

You can render really beautiful displacement maps with it, but you can also render some nice cell division animations. Here's how. You'll need to download the demo of Tinderbox 2 before you start.

你可以使用它来渲染非常漂亮的置换贴图效果，不过你也可以渲染出一些好看的细胞分裂动画，下面就教你怎么做，在开始之前，你需要下载 Tinderbox 2插件包的 Demo 版本。

A few years have passed since the cliff hanger conclusion of Tom Clancy's Splinter Cell: Double Agent , in which Agent Sam Fisher undertook a particularly dirty mission, full of questionable actions, in the shadow of the inexplicable and unmourned death of his daughter.

几年过去了，因为细胞分裂悬崖衣架结论汤姆克兰西：双重间谍，其中代理萨姆费舍尔进行了一次特别脏的任务，行动充满疑问的女儿，在他的阴影和无人哀悼死亡的莫名其妙。

The results showed that there was a negative relationship between H2O2 content and CAT activity, thus H2O2 content was low when CAT activity was high. There was a close relationship between H2O2 content and differentiation process. H2O2 could be an important signal transduction factor during bud differentiation. IAA oxidase activity was decreased firstly, and then increased, which affected IAA oxidase and degradation pathway and regulate ratio of cytokinin and auxin. With differentiation process continuing, PPO activity was increased, which could cause browning or vitrifaction of seedling, or even malformation.

研究结果表明，鹅掌楸组培再生过程中，过氧化氢酶活性与H2O2含量变化呈负相关，CAT活性较高时，H2O2含量则较低。H2O2含量与鹅掌楸组培苗分化进程密切相关，H2O2可能作为信号因子在芽分化过程中发挥重要作用；IAA氧化酶活性呈现先下降后增加的变化规律，从而影响IAA氧化降解途径，调控细胞分裂素与生长素含量的比值，影响鹅掌楸芽的再生；PPO活性随培养时间的增加而升高，引起组培苗的褐变或玻璃化，甚至生长畸形。

These angiogenic factors promote endothelial cell division and growth of capillary sprouting.

这些血管生成因子促进血管内皮细胞分裂和毛细血管出芽生长。

In this work, smears of ascitic fluid of mice 5—6 days after inoculation of Ehrlich carcinoma were stained by means of Feulgen reaction.

上述资料足以说明本药对Ehrlich腹水瘤的抑制作用，主要是由于它直接影响瘤细胞分裂繁殖的结果。

Intrinsic cell fate determinant Numb is the first protein found to be asymmetrically distributed during neural development.

Numb蛋白是神经发育中第一个被发现呈不对称分布的蛋白，是产生不对称细胞分裂的重要因素之一。

One of the serially aligned beadlike granules of concentrated ''.'chromatin'.

染色粒在细胞分裂早期，一条顺序排列的珠状染色质颗粒链构成了染色体

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
