| 摘 要： | 实体墙热工性能,过去多用简化计算和试验房测定法加以评价.但这些方法所得数据,前者不够精确,后者则有较大的局限性,同时也会带来计算和测量方面的误差.本文用计算机直接求解墙体导热微分方程,便可获得在任意外界条件作用下的墙体内表面温度.这样便可较精确地、方便地评价各种材质组成的墙体的热工性能.又,本课题还建立了过去无法计算的通风墙体的数学模型和计算程序.因此这是一项开拓型的工作.用数值计算法取代传统方法研究建筑热工性能,其前景是令人鼓午的.

| Abstract: | In the past, the thermal characteristics of a solid wall were often evaluated by a simplified calculation method or by an experimental means. However, these two methods have a few limitations. We argue that if we solve the partial differential equation of |
