For a long period of time, widely used in the production of components of an effective insecticide rotenone is mainly from the genus Derris root extract, collect rotenone from the root to dig down to two meters deep, the human cost of not only high-cost and easy caused by soil erosion, many of the genus Derris production has stopped growing, leading to the market with rotenone as the main active ingredient of the biological pesticide manufacturers shortage of raw material sources.

相当长一段时间，在生产上广泛使用的有效杀虫成分鱼藤酮主要是从鱼藤属植物中的根部提取，采集鱼藤酮的根要挖掘至地下达两米深，不仅人力成本耗费高，而且容易造成水土流失，不少鱼藤属植物的产区已经停止种植，导致市场上以鱼藤酮为主要活性成分的生物农药制造企业原料来源短缺。

Taking and data gathering that's not practical in a desktop computer.

同时，与数据采集不实际的一个台式电脑。

Vibroseis is a new type of seismic source which will not bring the danger and destructibility of dynamite and can bestir repetitious sweeping signal.

而高分辨率地震勘探是一个系统工程，从地震波的激发、检波器阵列的布置、数据采集、数据处理到数据解释都应该遵守高分辨率地震勘探的准则。震源是产生地震信号的源头，其信号质量直接影响地震勘查效果。

ICF实验靶物理诊断系统中的数据采集和处理系统是ICF实验中的重要组成部分。

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。
