用解析方法评价具有复杂导热体的围护结构及其节点和板缝连节处的热工性能是十分近似的。利用电子计算机程序,以及用电或水模拟试验解决这个课题的方法,也因种种原因而经常不能采用。最为可靠的方法是在人工气候室里进行室内研究或结构试验,以达到对围护结构与其节点的热工性能予以初步评价。但是这种研究极为困难,它要求 It is very similar to evaluate the thermal performance of enclosing structures with complex thermal conductors and joints between nodes and slab joints by analytical methods. The use of electronic computer programs, as well as electricity or water simulation experiments to solve this problem, can often be used for a variety of reasons. The most reliable method is to conduct an indoor study or a structural test in an artificial climate chamber to obtain a preliminary evaluation of the thermal performance of the envelope structure and its nodes. But this kind of research is extremely difficult and it requires
