摘　　要：分析装修施工过程对大气的污染流向及危害,通过计算污染物对人体造成的风险指数,确定风险指数与污染物浓度具有相关性;利用支持向量机方法获取回归估计函数,构建污染物浓度预测模型;基于光谱技术优化设计测量光学系统,设置温控电路;利用所得出的媒介厚度与光强关系,确定介质吸收常量;通过高通滤波器将窄带光谱分离,由此反演出污染物浓度。仿真实验证明,该方法水平测定结果与预测结果基本一致,可实现对污染物的识别与定量测量。This paper analyzes the air pollution flow and hazards during the decoration construction process,and determines the correlation between the risk index and the concentration of pollutants by calculating the risk index caused by the pollutants to the human body.It uses the support vector machine method to obtain the regression estimation function and construct the pollutant concentration prediction model to optimize the design of the measuring optical system based on the spectroscopy technology and set the temperature control circuit.It uses the obtained relationship between the thickness of the medium and the light intensity to determine the medium absorption constant and to separate the narrow band spectrum through a high-pass filter,thereby reflecting the concentration of pollutants.The simulation experiment proves that the level measurement result of this method is basically consistent with the predicted result,which can realize the identification and quantitative measurement of pollutants.
