摘要
在中密度纤维板(MDF)纤维管道气流干燥系统分析中常用的管道断面各项物理参数相同和纤维在管道断面上均匀分布等多项假设,具有可靠的理论依据。与其说是假设,不如说是忽略次要因素的一种近似,或一种简化。
Based on a hydromechanical analysis we found that the common asumptions,such as uniform distributions of the fibres and the constant values of some physical parameters in a tube section,had a solid theoretical fundamental.These assumptions can be treated as a simplification of a true situation.
