Rotenone derivatives from derris have been an important isoflavonoid with insecticidal activity.

鱼藤酮类衍生物是一类从鱼藤属等植物中提取出来的具有杀虫活性的异黄酮类化合物。

The soil faunal specimens collected belonged to 4 phyla, 6 classes and 12 orders. Nematoda was the only dominant group of medium- and small-sized soil fauna, occupying 94.3% of the total, while Coleoptera and Hemiptera were the dominant groups of large-sized soil fauna, with the amount of 79.7%.

共获得土壤动物4门6纲12目，优势类群中小型土壤动物仅线虫目1类，占总捕获量的94.3%；大型土壤动物为鞘翅目和半翅目2类，占总捕获量的79.7%。

Total average quantity of Phytoplankton is 687.56×10^4ind/L, and biomass is 8.888 3 mg/L; Zooplankton belong to 4 Phylums-31 Genus or Species, protozoon and rotifer have the most quantity (77.67%), Copepoda have the most biomass (1.193 0 mg/L), total average quantity of Zooplankton is 270.690ind/L.

浮游动物共4类31个种属，数量上以原生动物、轮虫为主，占77.67%，生物量桡足类最大，为1.1930mg/L，浮游动物总平均量为270.690ind/L。

During the period the author has particulanly studied in ecology and cultural technology of cladocera and rotifer.

在此期间，作者主要从事枝角类和轮虫的生态学及培养技术等方面的研究，内容包括：第一部分淡水枝角类批量培养的基础研究。

Food compositions of M. albus were investigated in areas of three counties in Hubei province. Diets of the M. albus with body length less than 100mm change with their growth: from Rotifera and Cladocera to Oligochaeta and Chironomidae.

通过对不同产地的271尾野生黄鳝的食性的研究表明，全长小于100mm的稚鱼，其食性随着全长的生长而变化，稚鱼前期以摄食轮虫、枝角类为主，后期以水生寡毛类、摇蚊幼虫为主。

Microbial community biota monitoring-PFU was used to investigate the miniature biological population- Ciliata , as the main research object in the aeration tank in Yan'erwan Wastewater Treatment Plant in Lanzhou.

在兰州雁儿湾污水处理厂采用微型生物群落监测方法——PFU法，以曝气池微型生物种群——纤毛虫类为研究对象，通过PFU监测及同期BOD5检测，发现污水处理厂曝气池纤毛虫物种丰富，以钟虫等固着缘毛目类为优势类群。

Only 8 species of Cladocera and 5 species of Copepoda were observed.

共鉴定浮游动物134属217种，其中原生动物95属153种，占浮游动物物种数的71%；轮虫27属51种，占23%；枝角类7属8种，占4%；桡足类5属5种，占2%。

It can be seen that the species composition of zooplankton comprised mainly of protozoa,followed by rotifers,copepods and cladocera,with an average density of 3.98×10~3ind/L.

从中可看出浮游动物种类组成以原生动物为主，其次是轮虫，桡足类和枝角类最少，平均密度为3.98×10~3ind/L。

60 Species of zooplankton were identified, among which there were Rotifera 34 species, Copepoda 13 species, Cladocera 6 species, among which Rotifera has an dominance for 55.02%, especially Brachionus sp.

浮游动物共鉴定到60种，其中轮虫有34种，桡足类13种，枝角类有6种。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
