| 摘 要： | In this paper,the permeable measurement equipment was made by authors.Thepermeability of four species of common wood was measured.These species grow in northeasternarea of China.The results indicated that 1)The experiment proved this equipment was reasonble instructure,good measurement precision and convenient use,and the wood permeability measurementwas satisfied.2)Wood permeability was the physical property of anisotropy in different grain direc-tions.The permeability of four kinds of wood in axialis are greater than that in crosswise,thepermeability of Pinus koraiensis and Larix dahurica in radial is greater than in tangential,andthe permeability of Populus davidiana Dude and Betula playphylla Suk in tangential is greater thanthat in radial 3) According to the data of four kinds of wood permeability in different grains direc-tion,the effect mechanism on wood permeability and different properties was discussed and ana-lysed.

| Abstract: | In this paper, the permeable measurement equipment was made by authors. The permeability of four species of common wood was measured. These species grow in northeastern area of China. The results indicated that 1) The experiment proved this equipment was reasonble in structure, good measurement precision and convenient use, and the wood permeability measurement was satisfied. 2) Wood permeability was the physical property of anisotropy in different grain directions. The permeability of four kinds of wood in axialis are greater than that in crosswise, the permeability of Pinus koraiensis and Larix dahurica in radial is greater than that in tangential, and the permeability of Populus davidiana Dude and Belula platyphylla Suk in tangential is greater than that in radial 3) According to the data of four kinds of wood permeability in different grains direction, the effect mechanism on wood permeability and different properties was discussed and analysed. |
