达到目的

The alarm valve should be installed vertically. When there is a fire in the protected area, temperature rises up, pressed water jet from sprayer, and the alarm valve is initiated to jet water onto fire. After 5-20 seconds, the delayer will sent out alarming signal to ring the bell for fire extinguishing.

当保护区某处发生火灾时，环境温度升高，闭式喷头的维护敏感元件破裂，压力水从喷孔口喷出并自动启动报警阀将水直接喷向火灾发生区域，延迟器延时5-20秒后发出报警信号，带动警铃以达到报警、灭火的目的。

Deliquescence of calcium sulfite under various conditions including temperature,pH,dissolving time,stirring rate and initial quantity was investigated in experiment.

亚硫酸钙的溶解浓度对氧化速率有非常重要的影响，课题主要研究CaSO3的溶解特性，描述了CaSO3在不同条件下(温度、pH、溶解时间T、搅拌速度、初始加入量等)溶解量的变化规律，进而找出CaSO3的最佳溶解条件，以达到提高氧化速率及石膏的生成率，防止堵塞和结垢的目的。

In an interview this week with al-Jazeera, Mr Putin made plain the basic conviction underlying these moans: that all American talk about Russia's democratic failings was so much realpolitik. Critics of Russia's human-rights record, he said,"are using this kind of demagogy as a means to pursue their own foreign-policy goals in Russia."

在本周与卡塔尔半岛电视台的一次访谈中，普京将隐藏在他诸多对美不满情绪之下的根本想法一吐为快：美国那些所有对俄罗斯民主进程失败的言论不啻为是权力政治的体现，他认为那些对俄罗斯人权记录的批评就像是在俄罗斯使用"一种煽动者的方式来达到其外交目的"。

It is shown that in complex system like L-tyrosine, using a locally dense basis set with a large number of atomic basis functions for the carbon atom of interest and smaller sets of atomic functions for the other atoms can not only save the disk capacity and computing time but also produce satisfactory results.

由从头计算获得的结果与实验值符合较好，说明对于具有复杂结构的多原子体系，对杂原子使用较小的基函数，而对所关心的碳原子使用较大的基函数以提高计算精度，这样可以达到既节省计算机空间与计算时间而不影响计算精度的目的。

It has physical adsorption and chemical adsorption of the double feature, you can have a choice of the adsorption gas and liquid in a variety of substances, in order to achieve bleaching refining, deodorization and decontamination disinfection purification purposes.

它具有物理吸附和化学吸附的双重功能，您可以在各种物质的吸附气体和液体的选择，以达到漂白精炼，除臭和净化消毒净化的目的。

It has a physical adsorption and chemical adsorption of the double features, can be selected by gas adsorption, liquid material, in order to achieve decolorization refining, deodorization and decontamination disinfection purification purposes.

它具有物理吸附和化学吸附的双重特性，可以有选择的吸附气相、液相中的各种物质，以达到脱色精制、消毒除臭和去污提纯等目的。

To illustrate the present depolarizer which be used to handle the SOP of the incoming light.

我们提出，当光行走的路程不同，叠加后不会产生光同调的理论，来达到解偏振的目的，是此研究的目标。

The design of signal processing circuit in this paper can achieve anticipative purpose in the ultrasonic detection receiver of the new rocket depth charge multifunction fuze and it offers definite reference value to farther research of ultrasonic proximity fuze.

本文对接收机信号处理电路的研究设计，能够达到预期的目的，对今后的进一步研究火箭深弹声近炸引信具有一定的参考价值。

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.
