试验研究了温湿度条件对瓦楞原纸含水率的影响，以及瓦楞原纸含水率对其弹性模量的影响，构建了含水率与温湿度的三维关系图。试验结果表明：瓦楞原纸的含水率既受相对湿度的影响，又受温度的影响，温度对瓦楞原纸弹性模量的影响比相对湿度的影响小；瓦楞原纸含水率随温度的上升而下降，随相对湿度的上升而上升；瓦楞原纸弹性模量随含水率的上升而下降。

The influence of temperature and relative humidity on moisture content of corrugated paper and moisture content on elastic modulus of corrugated paper were studied by experiments. The three-dimensional image among moisture content, temperature, and relative humidity was constructed. The results showed that the moisture content of corrugated paper decreases with increase of temperature and increases with increase of relative humidity; the effect of relative humidity on the moisture content of corrugate paper is greater than temperature; the elastic modulus decreases with increase of moisture content.
