摘要: <正>着重讨论速生杨木单板顺纹弹性模量预测模型 ,模型中考虑到单板的压缩率、单板中含胶量、单板的密度和单板的厚度等影响因素。结果表明 ,单板顺纹抗拉弹性模量的模型预测值与实际值之间能较好拟合 ,并且能够反映压缩率和浸胶量对单板顺纹抗拉弹性模量关系。笔者分析了速生杨木单板的压缩率与热压单位压力的关系 ,试验表明单板的压缩率与压力呈非线性关系。

Abstract: The models for predicting elastic modulus along the grain of poplar veneer were built,in which compression ratio,glue content,density,and thickness of veneer were considered.The results from experiments showed that the predictions from the models could seetle for experiments at given compression ratio and glue content.In addition,the relationship between compression ratio of veneer and hot pressure would be discussed in the paper,which would be non linear expression from experimental data.
