摘　　要：对热烟测试方法作了较系统的分析,结合两个工程的应用情况说明是一种了解烟气流动状况的方法。指出热烟测试方法仍需要进一步完善,如发烟装置和示踪烟气的选择、示踪烟气产生及注入流量的确定、火源与烟气对建筑物可能损害的防护等,并对如何处理这些问题进行了讨论,以期望热烟测试方法在重要建筑火灾安全评估中发挥更大的作用。The hot smoke test method is comprehensively analyzed, and proved to be a remarkable technique to gain understanding of the smoke flow in the buildings, by utilizing two of the engineering applications of hot smoke test as examples. Several aspects of hot smoke test that needs further improvements are also indentified, such as the selection of the smoke generator and the type of tracing smoke, the determination of the amount of the tracing smoke generated and injected to the fire plume, and the prevention of the damage to the building caused by the fire source during the test. Discussions are carried out on how to deal with these problems, which will probably be helpful for the promotion of the hot smoke test method.
