林火蔓延 meaning in English

forest fire a ealing
forest fire appealing

In order to increase the accuracy and the widely use of fire spreading model , the paper base on the change state of temperature of the calculus on fire area , use the law of energy conservation , it can give the change of the temperature field ' s mathematical model on the fire area
摘要为了提高林火蔓延模型的准确性和通用性，文中把火场看作一个动态温度场，并从火场上任一微元体任一时刻温度变化状态出发，应用能量守恒定律，建立火灾区域温度场动态变化模型。
The model can be made into difference equation of the temperature field that can be used to simulate calculation ; then we can get the set of edge point , and we can have the function of the fire line , and we can also have the burned area , the length of fire line and the space of fire area ; it also come to the conclusion that the main factor of forest fire is convection heat transfer
经差分处理，得到进行模拟计算的一组温度场计算方程；由边界点条件，求出边界点的集合后，拟合得出火线函数，积分后可得到时刻火场的过火总面积、火线长度和火场形状，同时进一步证实了对流传热方式是影响林火蔓延的主要因素。
