后生动物

The size structure of the metazoan zooplankton was analyzed by taking body mass as the size variable.

于2002年和2003年对该湖的后生浮游动物进行了采样，并以体重作为个体大小变量研究了浮游动物的个体大小组成结构。

Some environmental factors could confer a predisposition to depression by affecting the genome epigenetically — for example, increased maternal care in rodents causes an epigenetic change in the promoter region of the glucocorticoid-receptor gene.

一些环境因子可能赠予抑郁易感性，累及后生染色体—例如，在啮齿动物的糖皮质激素受体基因启动子区增加母体的忧虑可引起后生变化。

Flattened organisms unique to Ediacaran that form a group outside of metazoans (i.e., not animals).

震旦纪的特殊的扁平生物，形成一个超出后生动物之外的群组。

Flattened organisms unique to Ediacaran that do not form a natural group because they include some metazoans.

震旦纪的特殊的扁平生物，由于它们中包括一些后生动物所以没有形成一个自然类群。

In recent years,'Orsten-type' fossils, characterized by remarkable preservation of the soft tissue of putative embryos and arthropod larvae, have transformed our view of the early evolution of metazoans.

近年来，&奥斯坦型化石&（其特点是，假设存在的胚胎和节肢动物幼虫的软组织保存非常完好）已经改变了我们关于后生动物早期演化的特点。

Finally, it also achieved the aim of treating sewage with less sludge production discharged by combining MBR and the technology of intensified function of these metazoans, such as predations.

试验还通过将MBR技术与强化污泥系统后生动物的方法相结合，来实现减量剩余污泥的排放的研究。

The macro-organisms, including macro-plants, metazoans and trace fossils, 30 species of 23 genera and 4 macroalgal holdfasts, which are collected from Southeast Zhongqing and Northwest Guizhou, are described herein.

宏体生物广泛地生活于扬子地区伊迪卡拉纪陡山沱期古海洋中，描述了产自渝东南和黔东北伊迪卡拉系陡山沱组的宏体生物(包括宏体植物、后生动物和遗迹化石)共30属，23种，4个不明固着器，其中包括4个新属，5个新种，2个新修正属和1个新修正种。

The macro-organisms lived widely in the Yangtze Sea during the Doushantouian of the Ediacaran. The macro-organisms, including macro-plants, metazoans and trace fossils, 30 species of 23 genera and 4 macroalgal holdfasts, which are collected from Southeast Zhongqing and Northwest Guizhou, are described herein.

宏体生物广泛地生活于扬子地区伊迪卡拉纪陡山沱期古海洋中，描述了产自渝东南和黔东北伊迪卡拉系陡山沱组的宏体生物(包括宏体植物、后生动物和遗迹化石)共30属，23种，4个不明固着器，其中包括4个新属，5个新种，2个新修正属和1个新修正种。

In addition, there have no enough studies in the mechanism of spermatogenesis arrest induced by heat, and also there are many negative effects in the male contraceptive methods during these years like surgical ligation of vas deferens. All these factors have brings researchers to found a safety and efficacy methods for the problems in male reproduction.

因此，本研究通过高温处理未成年动物的模型，从细胞及分子水平探讨高温作用后生精功能障碍的机理，并对高温引起不育的机制进行深入研究；这些研究对阻止、延缓或减弱上述因素对人类生育能力的损害有重要意义，同时也为临床治疗一些男性不育、指导未成年男性生殖保健和探索男性避孕措施的研究提供理论基础。

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。
