摘　　要：本文作者对FDS源程序进行了改进,并利用改进后程序计算火灾过程中壁面热解形成图痕,作为火灾调查的方法之一,初步分析壁面烧损痕迹发展特征。该方法可以根据火灾场景、壁面材料、起火点功率的不同计算研究壁面燃烧痕迹形成规律,并提出使用该方法对火灾调查提供理论依据的可行性和重大意义。The original code of FDS program was improved and used to simulate the trace that a fire left on the wall. This method can be used for fire investigation, analyze the character of the development the trace primarily. The rule of the development of the trace can be concluded from different scene, material, and the power of the ignition point. Great significance and feasibility to supply theory base for fire investigation were put forward by using the improved program in this paper.
