有害

It is now widely accepted that governments and industry have a responsibility to take measures to protect citizens from potential harm associated with hazardous emissions and other harmful activities, to react in such a way as to minimize damages when accidents do occur, and to provide compensation in cases where damage to health and the environment does occur.

政府与行业有责任采取措施保护公众免受与有害物质排放和其他有害活动相关的潜在危害；在事故发生时能及时反应并使损害达到最低；对人类健康与环境造的成损害提供赔偿。

Smoking is injurious to health, especially to the lungs.

吸烟对健康有害，尤其对肺有害。

Gambling is condemned for the same reason: the effect of gambling is injurious not only to the individual but also to society.

赌博被认为是不正当的也是出于同样的原因：赌博造成的后果不仅对个人是有害的，而且对社会也是有害的。

Closer vertical proximity of the well bottom to the mine works increased the probability of adverse impact; closer lateral proximity to the mined area also increased risk of adverse impact.

好的底部的更加接近的垂直的接近度对矿工作的增加了有害冲击的可能性；与被开采的区域的更加接近的侧向接近度也增加了有害冲击的风险。

At this time, we have sent personnel to attend international IEC/TC111 activities. Under coordination by the Standard Administration of China, a technical committee is formed in corresponding to the TC111 WG3 (China WG3 working group). The task of forming a working group for test procedures of national standards for the density of toxic substances of electronic and electrical products is completed. The formation of a working group for industry standards for the prevention of pollution caused by electronic information products had been completed in October, 2004. This working group starts on the formation of standards for limits, test standards, leadless soldering standards, and certification and labeling standards.

目前，我们已经派员积极参与了国际 IEC/TC111的活动，在国标委的统一协调下，牵头组织了中国对应 TC111的 WG3的一个技术委员会（目前暂称为中国 WG3工作组）；组建电子电气产品有害物质浓度检测程序国家标准工作组的工作已经完毕；电子信息产品污染控制行业标准工作组已经在2004年10月组建完成，已经开始了制定电子信息产品有毒有害物质的限量标准、检测标准、无铅焊接标准、认证与标识标准的工作

In this work, GC-MS, ICP-OES, UV-Visible Spectrophotometry were employed to determine the trace concentrations of the above six hazardous substances, and a standard method system for screening primarily, extraction, qualitative and quantitative analyses of the six substances was established and their factors were analyzed. By evaluating the relative standard deviation, recovery, repeatability, limit of detection, linear relation etc., the optimum parameters were given and thus the precision of analysis was equal to or higher than the IEC 62321 standard, meeting the requirement of RoHS.

针对中国电子电气业在遵守RoHS符合性实践中存在的诸多问题，本文采用GC-MS，ICP-OES，UV-Visible分光光度法等，对我国南方和香港地区各类电子电气产品中六种有害物质进行痕量分析，建立了一套标准的六种有害物质初步筛选、萃取、定性、定量分析方法，并对此方法体系的影响因素进行分析，对其相对标准偏差、回复率、再现率、检出限、线性关系等进行评估，得出了优化测试参数，在此条件下其检测的精密度达到或高于国际IEC 62321标准，满足RoHS测试要求。

Quickly remove the harmful chemical gas such as ammonia, formaldehyde, benzene and toluene; Leach away various smokes, and lustrate other harmful gas that create by organism and mineral, make the air fresh.

快速去除氨、甲醛、苯、甲苯等有害化学气体、滤除各种烟味和驱除其它有机或无机物产生的对人体有害的气体，清新空气。

Commonly,office with air-condition lacks of natural airiness,people breathe out CO2,the fog that is coursed by smoking,some office equipment.These things emante maleficence to bulk in the office.There are wet resorting in the air-condition system,this becomes the "dirt-hiding place".Computers,displays,hand-holding telephone and other electric equipments can produce certain amount of ionization radialization.Some building materials also release certain injurant.

带空调的办公室一般缺乏自然通风，人们呼出的二氧化碳、吸烟产生的烟雾、某些办公设备散发的有害气体积聚其中；空调系统里有水分滞留，成为某些细菌、霉菌病毒的"藏污纳垢"之地；电脑、显示器、手持电话及其他电子设备均产生一定剂量的电离辐射；有的建筑材料本身也释放某些有害物质。
