A method is described for the simutaneous determining of 11 carbamate insecticides and their metabolites in rice .

本文介绍一种大米中11种氮基甲酸酯类杀虫刺及其代谢产物的多残留快速测定方法。

By contrast, organophosphate, carbamate and pyrethroid pesticide residues can be removed easily because of their instability.

有机磷类、氨基甲酸酯类及拟除虫菊酯类农药稳定性相对较差，不同操作对其有很好的去除作用。

Annexin B1 and arthropod formed an independent branch in the species phylogenetic tree; nemathelminth, plant, Ayes and vertebrate formed a branch; pprotozoa, cnidaria, amphibia and chordate formed another branch.

在物种进化上，Annexln B1和节肢动物为1支，新杆线虫、植物、鸟类和脊椎动物为1支，原虫、腔肠动物、两栖类和脊索动物为1支。

Most cladoceran abundances showed sharp declines in the presence of fish, while some rotifers, as well as their assemblage species richness, responded favourably to fish.

大多数枝角类丰度显示骤然下降当鱼类出现，然而一些轮虫，它们的群体种丰富，反映出有利的机制。

Maduramicin is a new type of polyether ionophore antibiotic, which can particularly kill and restrain coccidia - a kind of animal parasite which induce coccidiosis.

马杜霉素是一种新型的聚醚类离子载体型抗生素，可以特异性的杀灭和抑制对畜牧养殖业危害极大的动物寄生虫——球虫。

Two Soft Acales Coccus pseudomanoliarum Kuw. and C. hesperidum L. are difficult to be controlled in some oversea areas where parasitic wasps are not occurred.

They classed this insect under the Coleoptera.

他们把这种虫列入甲虫类。

This was attributed to high population growth rates for rotifers under these ecological conditions because of reduced copepod predation on them through a trophic cascade from fish.

这个归因于轮虫在这些生态条件下的较高种群增长率，这些生态条件是由于桡足类对它们的捕食通过一个鱼类高富营养阶段。

In two basins, Bohai and Qinglian, Rotifera contributed most to biomass in almost each size class, followed by copepod. Both the size range of the zooplankton and the body size at which peak biomass occurred were lower than in temperature lakes.

根据对两个子湖一一波海湖和青莲湖2002年和2003年生物量分布的分析与比较，2003年生物量均有所下降，在生物量分布的每个体重等级上轮虫基本上都是第一优势类群，其次是桡足类。

The content of heavy metals in 5 groups of animals(snail, diplopod, Diestrammena marmorata ,bat guano and Orthomorpha) and that in the soil and water in cave is determined, and the accumulation coefficient of all animal groups and pollution index of soil in cave is studied.

对5个动物类群（螺类、马陆、斑灶马、蝙蝠粪和山蛩虫）、洞穴土壤和洞穴水的重金属含量进行了测定，研究了各动物类群的富集系数和洞穴土壤的污染指数并进行了评价。

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.

交际能力和语法的关系应该是目标与途径的关系。
