摘　　要：运用有限差分法和反应系数法评价轻质麦秸复合墙体的传热特性,并将之与传统的砖混结构进行比较。结果表明:轻质麦秸复合墙体抵抗外界大气温度波动的能力是普通砖墙的8～10倍,具有良好的保温隔热性能;采用轻质麦秸复合墙体,其传热能耗能达国家要求的节能50%的目标,可作为新型节能建筑墙体材料在建筑行业广泛应用。The heat-conducting property of the wheat straw-based sandwich wallboard was evaluated with finite difference method and intergal transformation method and compared with the traditional construction brick wall in this paper. The results indicated that the wheat straw-based sandwich wallboard had better property of withstanding the difference of the outdoor environment than the brick wall, which was about 8 - 10 times of brick wall. In addition, the heat conductance of the wheat straw-based sandwich wallboard can meet the national demand of 50% energy saving of new building materials. It has good heat insulation and can be used either in interior or exterior for buildings and will have a bright future in China.
