居室中甲醛含量及其释放因子关系的研究

在改变温度及湿度的条件下，对某些新居进行了密闭室内甲醛浓度的测定。表明室内甲醛浓度随时间衰减。甲醛初始浓度较大时，随温度升高，湿度增大，室内甲醛含量会明显增加。同时指出，升温过程中，室内甲醛的浓度增幅，初期要大于后期；温度与湿度同时增大，在一定范围内会联合加剧室内甲醛污染。

A Study on Relation between Formaldehyle Content in a Closed Living Room and Its Releasing Factors

The formaldehyde concentration in a new closed living room was measured under the conditions of changing temperature and humidity. The results showed that the formaldehyde concentration reduced with lasting of time,and that the concentration increased promimently with rising of temperature or humidity when the initial concentration of formaldehyde was higher. Meanwhile, it was indicated that the rising range of formaldehyde concentuation at initial period was higher than that at final period. In addition,the increase of temperature and humidity can jointly aggravate the formaldehyde pollrtion in a certain range.
