Effect of intensity and work time of electric field on moisture gradient of Pinus massoniana wood

The moisture gradient along height of Pinus massoniana wood were tested and analyzed, which were treated by electric field for different intensity and work time, and were compared with the untreated wood. The results showed: (1)The intensity and work time of electric field had effect on the moisture gradient along height of the wood. (2) The moisture gradient alone height of the wood subsided with the increase of electric field intensity and work time. (3) But the direction of electric field had no effect on the moisture gradient along height of the wood. [Ch,5 fig. 26 ref.]
