摘要
对樟子松落叶、水曲柳落叶、水曲柳细、粗枝在Z0℃、78％相对湿度条件下的失水过程进行测定．获取相应过程动态方程所需参数——平衡含水率和水份交换导度。据此建立了相应条件下4种可燃物含水率时间动态方程。介绍了有关计算方法。并对平衡含水率Mc及比例系数片进行了讨论.为林火预测预报提供了理论基础。
Studies have been conducted on the desorption processes of four fine fuels: needles of Scotch pine,needles and two kinds of twigs from Manchurian ash trees during which parameters for dynamicmoisture content equation were obtained. The respective equations are presented here with discussions onthe calculation of fuel moisture content change and related processes.
