Based on the classifying, identifying and counting of protozoan and metazoan, the relationship between microfauna community structure and operation performance of WWTP was discussed in detail, which might be used to indicate and assess the WWTP and be benefited to build control system oriented sludge population optimization.

在介绍微型生物分类、鉴定、计数的基础上详细阐述了微型生物种群结构与污水处理厂运行状态的相关性与内在联系，力求为今后利用微型生物种群结构特性来指示、评价污水处理厂的运行奠定基础，并对此方面的研究方向进行了展望。

Since operation variables of activated sludge process have distinct effects on the microfauna communities (here defined as protozoan and metazoan), their community structure can be used to indicate and assess the WWTP operation performance.

活性污泥工艺运行状态对微型生物的种群结构具有显著影响，可利用微型生物种群结构来指示和评价污水处理厂运行，且有利于建立面向种群优化的控制系统。

Rotifer, wireworm exist in zoogloea at salt concentrations of 10000 mg/L while protozoa and metazoan disappeared when calcium chloride concentration is 30000 mg/L.

菌胶团中的微生物种类随着盐度的升高而减少，在盐度为10000mg/L时，有轮虫、线虫多种原生动物和后生动物，当盐度为30000mg/L时，菌胶团中的原生动物和后生动物消失。

The topologic architecture of metazoan trace fossils may be subdivided into 3 clusters, 8 basic topologic configurations, 3 combined topologic configurations and 21 topoichnologic kinds, which are considered to be related to ethologic classifications of trace fossils in origin.

后生动物遗迹的拓扑结构可归并为3 族、8 种基本拓扑型、3 种组合拓扑型和21 种拓扑遗迹类，它们与习性类有较好的成因联系。

Assuming that variations of the marine 13C/12C ratio are directly recorded in carbonate rocks, thousands of carbon isotope analyses of late Precambrian examples have been published to correlate these otherwise undatable strata and to document perturbations to the carbon cycle just before the great expansion of metazoan life.

新元古代较低的13C/12C比值被认为是前寒武纪特有的变化，这些变化包括所有有机质在海洋中的完全氧化以及生物产率的下降导致的热液二氧化碳的输入。通常热液中的二氧化碳被认为拥有较低的13C/12C比值。

The numerous macro-plants during the Doushantuoian were branching and semi-floated and erected on seafloor. They advanced the photosynthetic efficiency and increase oxygen in water to improve in environment for metazoans; and they served as a primary producer in the paleoecosystem to provide an alternative and new food of metazoan.

陡山沱期的宏体藻类多分枝并直立固着于海底，提高了光合作用的效率，增加了海中水体中的含氧量，不仅改善了环境，为依赖一定氧而生活、生长和繁殖的后生动物给予了必要的支持，而且作为生态系统中的必要基础，为宏体后生动物的快速发展和演化提供了一个新的食物源。
