摘　　要：运用ＩＳＯＲｏｏｍ方法在全尺寸室内墙角火源条件下进行了复合板装潢材料火灾特性的研究，详细讨论了复合板的点燃、火焰传播和炭化物性以及室内火灾的发展过程。在墙角火源条件下，室内火灾发展过程可分为四个不同阶段，而在每一发展阶段，东面和北面墙上复合板分别存在四个和三个明显不同的区域。当区域四内的复合板被点燃、燃烧面积急剧扩大时轰燃现象发生。炭化结果表明，墙上复合板存在两个剧烈燃烧区：一个发生在区域一，另一个在侧墙与天花板交界的区域。研究旨在为建立室内火灾条件下复合板装潢材料的火灾特性模型提供实验依据。A study on the behavior of plywood lining under a full\|scale room corner fire using ISO room method has been conducted. The behavior of ignition, flame spread and charring the lining as well as the fire growth in the enclosure have been discussed in detail. It was found that for the corner fire scenario four stages existed in the development of the room fire and in all the four stages of the linings responded differently in four distinct regions of the east lining wall and three of the north lining wall. The results showed that flashover did not occur until the lining fire in region 4 took place when the burning lining areas increased considerably and rapidly. The charring results showed two severe burning areas on the lining, one was in region 1 and the other was located along the wall\|ceiling interstices in region 2.\=
