分析了纤维素原料的含水率对原料自热特性的影响。该模型包括氧化，水解，和水的蒸发和冷凝的影响。完整的反应扩散模型的系统推导出，然后高导热系数和扩散率的情况下，即空间均匀的情况下，仔细检查。利用退化奇点理论证明了该模型至少可以表现出25种不同的分岔图
The effects of moisture content on the self-heating characteristics of stockpiles of cellulosic materials are analysed. The model includes the effects of oxidation, hydrolysis, and the evaporation and condensation of water. The full reaction-diffusion model for the system is derived and then the case of high thermal conductivity and diffusivity, i.e. the spatially uniform case, is closely examined. Degenerate singularity theory is used to show the model can exhibit at least twenty-five distinct bifurcation diagrams
