摘 要:
通过在直坡表面上对同种条件的林火蔓延的分析，建立各种坡度表面上不同条件下林火蔓延的数学模型，并对偏微分方程进行数字化求解，对各种复杂表面条件的火灾模型进行了合理的实验仿真。[著者文摘]

Abstract:
Through an analysis of fire perimeter growth for homogeneous conditions over a surface of constant slope, a mathematical model of fire growth for heterogeneous conditions and variable surface is proposed. The mathematical model is in the form of a system of partial differential equations that require a numerical method of solution. A simple numerical solution technique is described and example solutions are given for fires over a variety of complex surfaces illustrating that simulation results can be obtained in reasonable time.[著者文摘]
