林火的热辐射和光谱是林火具有的基本物理属性。无论是研究林火行为,林火监测和控制以及扑火人员的安全防护都直接有关。林火产生的热辐射,遵从一般的热辐射定律:W=εσT~4 (1)式中:W 为单位表面积、单位时间内总的辐射能量(卡/厘米·秒)或(千瓦/米~2);ε为比辐射率,即同一 The thermal radiation and spectrum of a forest fire are the basic physical properties that a forest fire has. Whether it is studying the behavior of forest fires, forest fire monitoring and control and the safety of firefighters are directly related. The heat radiation from forest fire follows the general law of heat radiation: W = εσT ~ 4 (1) Where: W is the unit surface area, the total radiant energy per unit time (cal / cm · sec) or (kW / 2); ε is the emissivity, that is, the same
