污染

Regional development occupies large land, develops lots of contents, relates to multifields including industry, construction, business and civicism, so it is necessary to identify its influence on nature environment such as air, groundwater quality, surface water quality and hydrological condition, sound, soil, plants, topographty and social environment such as population, traffic, economic structure. The countermeasures of carring through circular economy, controlling pollution sources, planning industrial structure scientifically, distributing reasonably, implementing cleaner production and total quantity control should be taken to promote regional sustainable development.

区域开发具有较大的不确定性，并且占地面积大、开发的内容广、性质复杂、建设周期长，通常的区域开发都有可能涉及到工业、城建、商业、人居、市政等多个领域的开发活动，所以区域开发必须结合区域开发的特征，准确识别其可能对区域内及其周边的空气环境、地下水质量、地表水水质及水文条件、声环境、土壤、植被、地形地貌等自然环境和人口、交通、经济结构等社会环境等产生的影响，并采取发展循环经济，减少污染生成的源头控制措施；科学规划产业结构，合理布局的预防性措施；源内达标、区域集中控制的污染治理措施；实施清洁生产、总量控制，推进区域环境与经济的持续发展。

Direct heating type is mainly used for the material that consists of some big particles, not sensitive to pollution and not prone to polluting environment, such as ore, PVC, composite fertilizer, clunch and coal.

其中直接加热型主要是用于颗粒大不怕污染和不易造成环境污染的物料的干燥如：矿石、PVC、复合肥料、粘土、煤等。

Because of specificity and high efficiency, the catalytic efficiency of cellulase is high(more 103~1013 times than general catalysts), the condition of catalytic reaction is mild and the catalytic activation can be adjusted and controlled, which can improve remarkably semblance and handle of fabrics during finishing fabrics by biological catalyzing, moreover cellulase can replace some chemical materials such as acid, cocain, chlorine and phosphorus etc, so as to decrease pollution, make no waste-water and protect environment.

由于酶具有专一性和高效性，采用生物催化，其催化效率高比一般催化剂高10~3～10~(13倍，催化反应条件温和，催化活性可调节控制，应用在纺织品处理上，能显著改善织物的外观和手感，并能取代一部分酸、碱、氯、磷化合物等化工原料，从而减少污染，不产生污水，有利于环保和生态。而且酶本身又无毒，容易生物降解，不会引起环境污染，所以酶处理已被公认为是一种符合环保要求的绿色印染加工方法。本文选用了市场上常用的纤维素酶R-10和纤维素酶ECS2610两种生物酶。

Air, water, and land pollution, for example, are seen as the result of collectivization of ownership.

比如，空气污染，水污染以及土地污染都被看做所有权集体化的后果。

Color guard pollution and light pollution -"invisible killer" harm in virtually!

仪仗队污染和光污染-"隐形杀手"伤害几乎！

Comparing Datong Area combined pollution index issued by State Environmental Protection Administration in 2005 with that in 2006,this paper gives an analysis of it and points out that both industry and civil heating has direct impact to the Datong area ambient air quality.

对国家环境保护总局发布的大同城市空气综合污染指数进行了分析，分析方法是比较2005年和2006年的空气综合污染指数，指出工业和民用采暖都直接影响大同市的环境空气质量。

In the first chapter, we research the dynamics of population which were in the polluted environment, we will: give the corresponding mathematical model;(2): obtain the explicit conditions for the threshold of the population by means of comparison theorem.

第一章是研究污染环境中种群的动力学行为，首先给出相应受污染系统的数学模型，然后研究系统中种群的持久生存和灭绝问题，在具体模型中，运用比较定理研究种群生存的阈值。

First,much basic knowledge is introduced.Then,it importantly introduces my perspective : in this paper the estimations of the parameters and coefficient of contamination for the simple regression model and studied when its response variables are contaminated by another random variable sequence it discusses that the interval estimation of posterior confidence probability of parameters on coefficient of contamination by using the method of Bayes inference.

首先介绍了一些基础知识，然后重点介绍了我所做的工作：讨论简单回归模型中响应变量受到另一随机变量序列污染时，模型参数和污染系数的估计方法。

In the past 15 years, we had probed into the indoor air pollution(environmental tobacco smoke,incense,cooking fume) as the main risk factors and diet as a probable confounder for lung cancer in nonsmoking Chinese women.

过去15年我们以室内空气污染（ETS，烧香，烹调污染）为重点，并以饮食为可能因素来探讨它们与肺癌的关系，但未发现这些空气污染物与肺癌有联系。

They could generally be divided into two categories: direct and indirect contaminant sources.

可以分为两大类，即直接污染和间接污染。

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。
