| 摘 要： | 采用扩散杯法研究了定向结构板内水蒸气稳态扩散系数。结果表明，定向结构板内平行于板面的水蒸气稳态扩散系数约是垂直于板面的水蒸气稳态扩散系数的１０倍左右。定向结构板内水蒸气稳态扩散系数随着板密度的增加而减小，并且与密度成二次函数关系。

| Abstract: | The steady-state diffusion coefficients of vapour in 5 types of OSB were measured by using diffusion cup method. It was indicated that the steady-state diffusion coefficients of vapour in direction parallel to panel surface of OSB were about 10 times as large as that in direction perpendicular to panel surface. With increasing the density of OSB, the steady-state diffusion coefficients of vapour decreases and the quadratic functional relation exists between them. |
