摘　　要：用自制的高压静电干燥装置,对两种木材(桐木、松木)进行干燥实验。实验结果表明,静电干燥能明显加快木材内水分的迁移速率,其干燥速率是自然干燥的3～5倍,并随静电电场强度的增强而提高。还对木材静电干燥过程中水分迁移机理进行了初步的探讨分析。By using the self-regulating electrostatic drying equipment, the electrostatic drying for wood is studied. The experimental result shows that the velocity of water movement in wood is distinctly quicker under electrostatic field than that in the atmosphere. The drying rate under electrostatic field is 3 to 5 times of that in the atmosphere. And it increases with the enhancement of the intensity of electrostatic field. In addition, the preliminary study of mechanism of water move in wood was done.
