讨论了循环响应导纳方法及其在理想动态条件下评估多孔织物与水分含量相关的热性能的适用性。分析了复合稳定土墙织物中隔热定位的影响。给出了一系列稳定土材料与其饱和度 Sr 相关的与湿度相关的非稳态参数 Y、f、ψ 和 ω。给出了可直接比较使用传统材料和稳定土的特定横截面复合墙体织物的数据。根据对墙体非稳态参数的总体影响，分析了稳定土墙织物内含水量分布的影响。循环响应导纳方法经过修改，纳入了与湿度相关的非稳态参数，并讨论了对导纳、衰减和时滞的影响。
The cyclic-response admittance method is discussed along with its suitability for assessing the moisture-content-dependent thermal properties of porous fabrics under idealised dynamic conditions. The effects of insulation positioning in composite stabilised earth wall fabrics are analysed. The moisture dependent non-steady-state parameters of Y, f, ϕ and ω are presented for a range of stabilised earth materials in relation to their degree of saturation, Sr. Data to allow direct comparisons between specific cross-sectional composite wall fabrics using both conventional materials and stabilised earths are given. The effects of moisture-content distribution within stabilised earth wall fabrics is analysed in terms of the overall effect on the wall's non-steady-state parameters. The cyclic-response admittance method is modified to incorporate the moisture dependent non-steady-state parameters and the effects on admittance, decrement and time lag are discussed.
