英文摘要： The concept of Systems Fire is put forward in which the approaches to determination and its application for classification of trajectory generated manifold in complex systems of fire will be studied. The following aspects are planned to study: The research of mechanism for complex chemistry of fuel, in which facility is mainly composed of characteristics interactors and chemical analyzers, CHEMKIN and COSILAB et al. software packages which can couple fuel complex chemistry and predict the flame structure are used for numerical simulation；Study on dynamic analysis of reaction mechanisms of fuel complex chemistry and construction of reduced kinetic mechanism； Study on modern methods and models about numerical simulation and chemistry-turbulence reaction；Study on analysis of computational singular perturbation（CSP）and construction of DAEs（model reduction）；Study on analysis of intrinsic low-dimentional manifolds（ILDM）；Study on trajectory generated manifold based on analysis of scales about time and space in complex systems of fire. By the above studies, The idea of Systems Fire is explored.
