<正>一、前 言 木材电阻值的测量是对木材电学性质研究的基本手段之一。这方面的研究工作已报道很多。A.J. Nanassy从实验中得出结论,存在一个使木材损耗因子最小的频率fdmin。

When the resistivity of wood is measured, the results vary with the time of measurement because of the affection of absorption current. In order to get the true resistance independent of the time of measurement, both the charge and discharge curves arc recorded with a recording meter. By subtracting one from the other and then calculating the data available the true resistivity of wood is obtained.
