Article 58 Whoever imports radioactive wastes or radioactively polluted articles into the territory of the People's Republic of China or transfers them via the territory of the People's Republic of China shall be ordered by the customs to return the said radioactive wastes or radioactively polluted articles, and shall be imposed upon a fine of not less than 500,000 Yuan but not more than 1,000,000 Yuan in addition; if a crime is constituted, he/it shall be investigated for criminal liabilities.

第五十八条向中华人民共和国境内输入放射性废物和被放射性污染的物品，或者经中华人民共和国境内转移放射性废物和被放射性污染的物品的，由海关责令退运该放射性废物和被放射性污染的物品，并处五十万元以上一百万元以下罚款；构成犯罪的，依法追究刑事责任。

In order to have a good understanding of the causes of the event,a detailed analysis was made of the weather condition s during the time period by means of the air pollution index,conventional meteorological data,radiosonde data and AWS data.

为了了解造成这次持续重污染过程的原因，利用同期污染指数、常规气象观测资料、探空资料及自动站气象资料，对这一期间的空气污染气象条件进行了较为详细的分析。

The results showed that the quantities of bacteria in the petroleum contaminated soil were about 100 times more than that in the non-contaminated soil,the quantities of fungus and ray fungus in the contaminated soil were also extensively more than that in the non-contaminated soil.17 bacteria strains and 11 fungus strains for petroleum biodegradation were screened from the contaminated soils.

结果表明：石油污染土壤中的细菌总数是未污染土壤的100倍左右，其真菌和放线菌数量也明显超过未污染土壤。

On that basis,the authors used the single-factor assessment method and multi-factor assessment method(comprehensive pollution index and Nemeron pollution index)to assess the data of groundwater pollution by this refuse landfill site.

结果表明，该垃圾场对地下水的污染极其严重：综合污染指数可达到59；单项污染组分如NO2-、NH4+、COD等普遍比参照值高出几十倍，致癌物质NO2-则高出340多倍。从水质的角度看，地下水中有的污染物(NO2-、NH4+、COD)已经超出地下水Ⅲ类水质标准数十倍甚至100多倍，到了不能饮用的程度。

The research analysed the current status and pollution treatment research review from municipal refuse output, waste physical component, hazards, heavy metal pollution. On the basis of overall understand of current treatment situation about main municipal refuse landfill site of Fujian province. By the simulated test, utilizing 7 kinds of physical adsorbents (zeolite, incineration ashes, slag, plant ash, charcoal, ochre, active carbon), 4 kinds of chemical flocculant FeSO_4, AlCl_3, FeCl_3, Al_2(SO_4_3, and 3 kinds of hyclrophytes, we carried through the pollution removing study of heavy metal in landfill leachate and discussed removing effect of different physical adsorbents, chemical flocculant and hyclrophytes.

并在对福建省主要城市生活垃圾的处理现状全面了解基础上，通过室内模拟试验，分别利用7种物理吸附剂(沸石、焚烧灰、炉灰、草木灰、木炭、赭石、活性炭)、4种化学絮凝剂FeSO_4、AlCl_3、FeCl_3、 Al_2(SO_4_3和3种水生植物进行垃圾渗滤液中重金属的污染去除研究，比较不同物理吸附剂、化学絮凝剂和水生植物对垃圾渗滤液重金属污染的去除效果，试图从中筛选出治理成本低和治理效果好的城市垃圾渗滤液重金属污染修复技术，供南方城市垃圾处理场推广应用。

Based on residual sensitivity matrix and signs of residuals, this paper presents a new method to determine the possibility of existence of the worst residual contamination. Then a new method is presented to identify the worst residual contamination based on signs of measurement residuals.

文中基于残差符号信息研究状态估计中的残差污染问题，探讨了基于残差灵敏度矩阵和残差符号判断存在严重的残差污染的可能性，在此基础上，提出了利用残差符号信息识别严重的残差污染的方法，用简单的图示直观地描述了这一方法。

And a variety of heavy metal exist in the soil that the dependency analysis that heavy metal pollutes makes clear smeltery is circumjacent the compound pollution type of different level, different combination, farm ecosystem is put in the trend of compound pollution.

而重金属污染的相关性分析表明冶炼厂周边的土壤中存在多种重金属不同程度、不同组合的复合污染类型，农田生态系统存在复合污染的趋向。

There are many kinds of pollution, like sound pollution, air pollution and water pollution.

有许多种污染，像声音污染、空气污染和水污染。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
