On base of the former theoretical analysis , from the numerical simulation , analysis the thermal comfort of south room in the dwelling building , after using the pcm in the wallboards . from changing the enthalpy , thermal coefficient and the thickness of the pcm wallboards , analyzing different parameters how to affect the 通过改变相变墙体层的焓值、导热系数和厚度,分析不同的参数值对于房间整个冬季供暖能耗的影响,为将来相变墙体的实际应用做出理论指导。
The r esults of calculation and analysis indicate : the bracing effect from wallboard increases the load capacity of wall stud by 1 . 6 - 1 . 8 times ; the reasonable distance between fasteners of wall stud is l / 8 , l is the length of wall stud ; there is no necessity to considering bracing effect from wallboard in the direction of perpendicular to wallboard 分析结果表明：考虑支承效应后，墙体立柱的承载能力比原来提高了1 . 6 1 . 8倍：立柱墙板连接件间距取s = l / 8较为合理， l为立柱的长度；可不考虑墙板对立柱沿垂直墙面方向提供的支承效应。

The thermal storage and heat transfer of pcm wallboards were studied , the ‘ decrement factor ’ and ‘ time lag , which are used to evaluate the material with constant thermo physical properties , can ’ t be used to evaluate the pcm wallboards , because the melting or freezing of pcm can charge or discharge high latent heat during a narrow temperature range , which causes different temperature distribution in the walls and different surface heat flow into the indoor environment 探讨了墙体相变建筑构件的蓄热、传热特性。与常物性建筑构件对室外温度波动衰减(用衰减系数表示)和延迟(用延迟时间表示)的特性不同,相变建筑构件在较窄的范围内有大量潜热的吸收或释放,从而显著的影响其温度分布和表面向室内的传热速率。
Based on the tests of multi - ribbed composite wallboard , the characteristic of wallboard under different loading states have been analyzed in this paper , the corresponding mechanics computational models have been proposed , the multi - ribbed composite wallboards have been equivalent to uniform silicate wallboards , the practical calculated formulation on elastic - stiffness of multi - ribbed composite wallboard has been proposed , the calculation results accord ell with the tests results , so that the proposed formulation can be used in practice 摘要在密肋复合墙板试验研究的基础上，分析了密肋复合墙板在不同受力状态下的受力特点，提出了相应的力学计算模型，并采用刚度等效原则将密肋复合墙板等效为均匀的硅酸盐板，建立了密肋复合墙板弹性刚度的实用计算公式，计算结果与实测结果符合较好。
This is a true story happened in japan , to decorate room , someone removed wallboards . in general , the structure of japanese style building is of double layers wall covered by lime , and the inside is empty . when he removed the wallboards , he found one gecko was fixed there , one nail from outside board tacked its tail 在日本，发生了一件千真万确的事:有人为了装修家里，拆开了墙壁日式住宅的墙壁通常是中间架了木板后，两边批上泥土，其实里面是空的。他拆墙壁的时候，发现一只壁虎被困在那里,一根从外面钉进来钉子钉住了那只壁虎的尾巴。
