1、哈尔滨工业人学]：学硕+学位论文大。此外，还利用FLUENT6．1软件模拟了室内污染物的浓度场，以及气流的速度场。通过多次改变进口的风速得到了理想的进口风速控制在0．15-0．20m／s时，采用上下同时排风的强制通风方式，位于成人呼吸高度(1，2m)以上的区域的甲醛浓度均低于国家标准。对现有的室内空气的评价模式进行了对比，确定了适合于评价哈尔滨市室内空气污染的沈氏综合指数法。利用沈氏综合指数，对随机选取2004年检测中20户居民住宅的50个不同功能房间进行室内空气污染状况进行评价，结果表明：重污染6家，中污染2家，轻污染10家，清洁的1家。介绍了一种新的化学污染的评价方法一

2、对数指标评价法。利用已知C0。和TVOC评价指标一dcd和dTv，定义了甲醛的对数指标的公式。通过计算和分析，得到了人的不满意率与对数指标成线性关系。通过曲线拟合，得到了计算不满意率与甲醛浓度的公式。关键词建筑装修；室内空气；污染物检测；数值模拟：品质评价坠垒鎏三些奎兰三兰竺圭兰竺篁兰AbstractLocatedinachillyarea，Harbinhastheheatingperiodofalmost6months．OwingtOthewindy,weatherandtheoutdoor，noises，residentshavetOcloseorevensealthe
