室内甲醛的分布特征与方差分析
Distribution Characteristics and Variance Analysis of Indoor Formaldehyde

由于室内甲醛气体超标而引起的呼吸道疾病发病率逐年提高，越来越关注室内甲醛质量。本文主要通过Matlab拟合出在密闭空间内，时间和温度对甲醛浓度的影响的模型以及在自然通风的环境下，室内甲醛的空间分布情况模型，同时拟合甲醛浓度时序曲线，对甲醛浓度进行预测以及方差分析。经过对室内甲醛的数据进行数值拟合和方差分析，以此得出室内甲醛的特征并判断出适宜的居住情况，帮助人们了解室内甲醛。
As the incidence of respiratory diseases caused by excessive indoor formaldehyde gas increases year by year, more and more attention is paid to the quality of indoor formaldehyde. In this paper, the influence model of time and temperature on formaldehyde concentration in a confined space and the spatial distribution model of indoor formaldehyde in a naturally ventilated environment are mainly fitted by Matlab. Meanwhile, the time series curve of formaldehyde concentration is fitted, and the formaldehyde concentration is predicted and analyzed. Through numerical fitting and variance analysis of indoor formaldehyde data, the characteristics of indoor formaldehyde were obtained and suitable living conditions were determined to help people understand indoor formaldehyde.
