The noxious gas contained in the tail gas out of garbage incinerator and coal burning boiler is collected by bag filter with japanese techniques, This technology can achieve desulfuration and harmness gas through ejecting slaked lime dry power and reaction auxiliary agent to fult gas, sulfur dioxide and harmful gas.harmful gas and slake lime carry chemical reaction adequately,forming solidastate calcium sulfate and and other attachments, which will either adhere to stive or coacervate into nice granule and finally been absorbed.

垃圾焚烧炉尾气中的有害物质和燃煤锅炉煤中的硫燃烧后主要是以二氧化硫的形态存在，这种呈气态的二氧化硫和有害气体是无法用任何其它种类除尘器收集和捕捉的。本技术是通过向含有粉尘、二氧化硫和有害气体的烟气中喷射熟石灰干粉和反应助剂来实现脱硫、脱有害气体的。二氧化硫、及有害气体和熟石灰在反应助剂的辅助下充分发生化学反应，形成固态硫酸钙(CaSO4)和其它附着物，附着在粉尘上或凝聚成细微颗粒，随粉尘一起被袋式除尘器收集下来。

Digital image processing technology,the present reseach level about image alarm system is to separate eyewinker from monitoring image,and to judge whether the eyewinker is harmful according to the size of the area of object,this method is imprecise and suspectable.The image recgnition alarm system isan apply on image processing technology.when a foreign object enter monitoring place,we will segment、measure object,and analysis、judge through proportion characer or invariant monent.the result of the parameter will decide whether the eyewinker is harmful,if the object is harmful ,system will auto-startalarm device.

而本设计的主要特点是基于了数字图像处理技术，目前传统图像报警系统的研究水平是将异物从监控图像中分离出来，然后依据异物面积的大小来判断异物是否有害，它对异物有害的判断十分不准确，这种判断结果的有效性是很值得怀疑的；针对于这些弊端，本课题在数字图像处理技术上的应用是对监控场所进行全景监控，如有异物进入，对异物进行分割、测量，从不同的角度进行了分析和判断，进而决定异物是否有害，若满足场景所规定的有害条件，则启动报警装置，发出报警信息。

Vidicon collect simulate image in period of time and send to computer or DSP chip through video collection card digitlization,use computer to gain eyewinker and process digital image processing:using image area segment and boder measure to calculate area and perimeter;using image smoothness to wipp offthe infection of yawp;using dynamic background and image suited technology to overcome the infection of ray;calculation the parameter of eyewinker(area, perimeter,round measurement, proportion characer and invariant monent),using least norm to design the linearity classify parts,using image matching technologyto classify eyewinker,and to judge whether the eyewinker is harmful to diff background,if the eyewinker satisfy the character require of harmful object ,system will auto-stsrt alarm device. If there ia not have found any eyewinker, Vidicon will collect new simulate image and make processing.

本设计是将摄像机或高频头采集到的模拟图像经过视频采集卡数字化后送入计算机或DSP芯片，利用计算机对采集到的一定时间段内的图像进行异物获取，并对异物图像进行数字图像处理：利用图像区域分割和边缘检测以便进行面积和周长的计算，利用图像平滑去除噪声的影响，利用动态背景运动检测法和图像配准技术克服光线的影响，并通过异物的各类参数（如面积、周长、圆形度、比例特征和不变矩等）的计算，采用最小范数分类法设计了线性分类器，利用图像匹配技术对异物进行分类，从而判断异物是否有害，针对于不同的背景，若异物满足有害物体的特征要求，则认为物体有害，自动启动报警装置，如果没有发现有害异物则新摄入的图像将取代前一时间段的图像再进行图像处理。

Content characteristics of five kinds of detrimental elements,As,Cr,Cd,Pb,S,in iron ores imported from 23 countries,totally 490 batches,within recent two years were investigated by statistical techniques.Based on data distribution, interquantile robust statistics,and a brand-new data description technique,kernel density estimation,were used to acquire the standing values of detrimental elements.Multivariate statistical methods,including Principle Component Analysis and Factor Analysis,were used to ...

对我国进口铁矿石中的环境有害元素As、Cr、Cd、Pb、S的含量进行了总体统计分析，选用了四分位稳健统计分析及内核密度估计分别对铁矿中的有害元素As、Cr、Cd、Pb、S的含量的代表值进行估计，探讨了两种方法在代表值估计方面的特点，并使用主成分分析、因子分析等多元统计分析方法对有害元素的含量特征进行整体分类描述，确定了含量特征整体分类的主要有害元素，全面了解进口铁矿中涉及安全、环保等有害元素的质量状况。

According to the international methods of pest risk analysis and characteristics of urban forestry in Beijing,a quantitative risk assessment system in Beijing for the main non-indigenous pests was proposed.This system was used to analyze three non-indigenous species, Dendroctonus valens,Hyphantria cunea and Apriona swainsoni. The results show that the risk of these three species in the Beijing area is 2.46, 2.30 and 2.02, all highly risky.

该文参照国际上有害生物风险分析方法，结合北京地区城市林业特点，提出北京地区重大外来有害生物风险量化评估体系，并应用该评价体系，进行了红脂大小蠹、美国白蛾、锈色粒肩天牛对北京地区的风险评价。3种有害生物的量化评估值分别为红脂大小蠹2.46、美国白蛾2.30和锈色粒肩天牛2.02，因此对北京地区而言，3种昆虫皆为具高度风险的森林有害生物。
