Better diaphaneity and DO, lower velocity of flow, with abundant aquatic biology were also found to be propitious to form complex biofilm, and to the enrichment of phosphorus and nitrogen in the biofilm.

较高的水体透明度、溶解氧水平，较低的水体流速，以及丰富的水生生物的存在有利于形成结构较复杂的生物膜，利于天然水体中生物膜对水体中氮磷的富集。

Based on toxicity mechanism, a QSAR model was established and used to explain the toxicity of organic chemicals to fathead minnow and Photobacterium phosphoreum, which showed good relationships with wide range of organic compounds.

根据毒性机理，从理论上推导出有机物的定量结构—活性方程，并用来解释有机物对呆鲦鱼和发光菌的毒性，成功地阐述了有机物对水生生物的毒性机制，区分了有机物对不同生物的毒性的联系和区别，为有机物生物活性预测提供了新的思路。

The invention relates to biological feed, in particular to biological feed produced with kitchen waste and filter mud of sugar-refinery, and belongs to novel renewable biological feed and a production method in the resource environmental field. The components adopt kitchen waste and filter mud of sugar-refinery (calcium carbonate content of more than 75 percent to 85 percent) as the raw material.

Experiments were conducted to measure the impact of biofouling on the growth and reproduction of pearl oyster Pinctada martensii.

主要研究定期清除污损生物的合浦珠母贝与不清除污损生物的合浦珠母贝在生长及繁殖上的差异，用以说明污损生物对合浦珠母贝的生长及繁殖的影响。

Sequence analysis showed that the size of 16S rRNA gene was in 1235 bp, and lacking several regions which regarded as eukaryotic sequence, was more similar with prokaryotes than eukaryotes in sequence structural feature; it could be implied that the microsporidia had split from ancient eukaryotes very early in time on the phylogenetic tree.

序列分析表明，16SrRNA基因大小为1235bp，缺乏多个被认为是真核生物序列的区域，序列结构特征更多地类似于原核生物的，在进化上，推测微孢子虫在很早以前与原始真核生物产生分歧；分子进化分析发现，同属的微孢子虫可以处于系统进化树不同的分枝。

Form PLA is a nonvirulent macromolecular compound with biocompatibility, which used in the manufacture of new biodegradable plastics, fiber, and biomedical material.

型乳酸，分子式C3H6O3，为含有氢氧基的有机酸，是生物的代谢中间产物。L型乳酸可以在动物和人类细胞中新陈代谢因为这些细胞含有L型乳酸去氢酵素。L型乳酸还可用於生产L型乳酸聚合物。L型乳酸聚合物属於无毒的高分子化合物，具有生物相容性，可用於制造生物可分解的塑胶、纤维以及生医材料等。
