摘　　要：论证了一般热灾害系统的多重特性。提出非线性特性是一般热灾害系统（含火灾系统）本质特性的观点。将热灾害过程中存在的特殊现象与对应的非线性动力系统的复杂和奇异行为对应，由此可通过研究非线性动力系统动力轨道的拓扑和演化特性，研究特殊热灾害现象。指出非线性作用是特殊热灾害现象产生的最根本机制。The multiplicity of the characteristics of a general thermal disaster system (fire system included) is demonstrated. The statement that non-linear is the essential characteristics of a general thermal disaster system is put forward. Irregular behaviors of a thermal disaster system can be corresponded to the dynamical behaviors of the non-linear dynamic system relating to the thermal disaster system. As a result,irregular phenomena of a thermal disaster system can be studied by studying the topological characteristics and evolution performance of the non-linear dynamic system. It is also pointed out that non-linear is the main source to cause the irregular thermal disaster phenomena.be corresponded to thedynam icalbehaviorsofthe non- linear dynam ic system relating to thetherm aldisastersystem . As a result,irregularphenomena ofa therm aldisastersystem can bestudied by studying thetopologicalcharacteristicsand evolution performanceofthe non- lineardynamicsystem.
