宾馆内空气中甲醛与温度的关系分析

按季度对室内甲醛进行监测,同步记录采样点温度。监测数据按季度进行统计分析,发现宾馆内甲醛释放浓度受温度影响显著(r=0.829),且二者年变化规律呈倒"V"型,峰值出现在第3季度;在一定的时间区间内,甲醛合格率年变化趋势呈正"V"型,第3季度甲醛合格率达到全年最低点,其与采样点温度之间呈极显著负相关(r=-0.941)。甲醛的释放具有很强的季节性,其释放周期应按年进行统计。

Analysis of the relationship between indoor formaldehyde and temperature in the hotel

3 major hotels and the 18 sampling points were selected for determination quarterly of indoor formaldehyde,the temperature of sampling point was recorded synchronously.Quarterly analysis of monitoring data show that the temperature significantly affects the formaldehyde releasing（r=0.829）,and their variation trends in a year present inverted ＂V＂ type,the peak appears in the 3rd quarter.In certain time,trend of the change about the passing rate of formaldehyde in a year presented positive ＂V＂ type.In the third quarter,the passing rate of formaldehyde reaches the lowest point of a year,which shows extremely significant negative correlation（r=-0.941） with the temperature of sampling point.Formaldehyde release has strong seasonal,the release cycle should be based on years of statistics.
