采用介电式含水率仪对山毛榉常规干燥材及热处理材的含水率进行了测量，并与烘干法测量结果进行了对比分析，采用最小二乘法，分别拟合出了180℃、195℃和210℃山毛榉热处理材的校正曲线。180℃、195℃和210℃山毛榉热处理材的介电式含水率仪校正曲线分别为， y＝1.2923 x＋0.2783， y＝1.3920 x＋0.7473， y＝1.6445 x＋1.4892。结果表明，常规干燥材的电测法结果能很好地反映其实际含水率水平，而热处理材的电测法结果则普遍大于烘干法，3种热处理材均呈现出随含水率的增高，差值随之增大的趋势，且随着处理温度的升高，差值愈大。

Dielectric moisture meter readings were compared with gravimetric moisture content ( actual MC ) for kiln-dried and heat-treated beech wood .The meter readings corresponded closely with actual MC for the samples of kiln-dried lumber .In contrast , the meter readings of the heat-treated specimens were always higher than actual MC values, and the difference showed a strong positive correlation with heat treatment temperature .In order to predict actual MC from the meter readings , linear calibration curves for the 180℃, 195℃, and 210℃heat-treated beech wood were respectively fitted by the least squares method , the regression equations also were presented in this paper .
