Research on methyl bromide alternatives is one of the hot issues in the area of current pest control. To study and develop new alternative fumigant, re-evaluate current fumigants are the focus of methyl bromide alternatives research.

溴甲烷替代研究是当前有害生物控制领域的热点问题之一，研究开发新的替代熏蒸剂，重新评估已有熏蒸剂，是溴甲烷替代研究工作的重点。

Fumigants, by their chemical nature, are reactive chemicals. They can have unwanted and adverse effects on the treated commodity. It is essential to be aware of these effects when choosing a fumigant for a particular situationr.

由于化学性质决定了熏蒸剂都是活泼的化学物，它们对所处理的货物在不同的程度上会产生不利的有害影响，因此，在一些特定的情况下，选择熏蒸剂时最基本的一点就是要了解熏蒸剂对货物的影响。

In a fumigation, a gas is added to an enclosure for the purposes of controlling or eliminating undesirable organisms.

熏蒸是将有毒气体引入密闭的环境中以控制或消除有害的有机体。

However, because of the positive sequence of fundamental frequency, there are still some shortages for wavelet transform in the use of harmonic measurement of three-phase dissymmetrical system. A new approach of harmonic measurement based on Period-interleaving of MALLAT arithmetic for dissymmetrical system is put forward. Analysis and experiment based on TMS320LF2407 Digital Signal Processor are made. And the result of experiment reveals that the proposed method based on Period-interleaving is valid in the use of harmonic measurement of three-phase dissymmetrical system.

但是，目前小波变换在三相不对称系统的谐波检测中存在着无法分离基波正序信号的不足，本文就此提出了一种用于三相不对称系统的基于周期交错的小波MALLAT多分辨率分解的测量方法，详细介绍了该算法的原理、流程及计算公式，同时以TMS320LF2407数字信号处理器为核心建立了实验系统对该算法进行了实验，实验结果证明该周期交错－小波变换算法可以有效地检测出三相不对称系统中的有害电流。

Smoking is also gad for your heart.

抽烟对你的心脏有害。

Beijing has imposed bans for old-fashion cars and leaded gas as well as set severe restricts to car emission. During the Olympic game, the license plates numbers are varied into odd and even in order to cut the emission in half.

多年来北京市已在淘汰老旧汽车、禁用含铅汽油、提高尾气控制标准方面做了许多工作，又在奥运期间施行"单双号出车法"，使大气中的有害气体含量降低了一多半。

The hazardous substances in welding and allied processes have two kinds of states,which including graininess and gaseous state.

焊接及其相关工艺过程中的有害物质有2种形态，即颗粒状与气态。

When gaslight replaced kerosene lamps, but already, and flickering flames in extinguishing produce harmful gases, After has invented, and in public places, but due to the use of combustion hissed and light shoulds not be too bright, used for indoor.

那时煤气灯已代替煤油灯，但火焰闪烁不定，而且在熄灭时产生有害气体；弧光灯也已发明，并在公共场所使用，但由于燃烧时发出嘶嘶声而且光亮过于耀眼，不宜用于室内。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
