摘　　要：在麦秸砌块墙各向异性传热机理研究的基础上,对不同密度麦秸砌块墙平行和垂直热流方向的导热系数进行试验研究。结果表明,低密度时麦秸砌块墙垂直热流方向的导热系数大,高密度时结果相反。但随着密度的增大,垂直热流方向与平行热流方向的导热系数差值增大。Based on the research on heat transfer mechanism of anisotropic wheat straw-bale wall,this paper respectively tests the thermal conductivity of wheat straw-bale wall parallel to and perpendicular to heat flow direction with different densities. The results show that the thermal conductivity of low-density wheat straw-bale wall perpendicular to heat flow direction is larger than those parallel to heat flow direction,and the thermal conductivity of high-density wheat straw-bale wall perpendicular to heat flow direction is smaller than those parallel to heat flow direction. However, compared with the thermal conductivity of wheat straw-bale wall parallel to heat flow direction,the experimental value difference is increasing with density of wheat straw-bale growing.
