用烘箱实验方法研究了红松锯木在堆积存放条件下的热自燃问题，测得了红松锯末在实验条件下临界着火温度，并给出了堆积尺寸与周围环境温度之间的临界关系式．
The autothermal combustion of Korean pine sawdust was studied by means of oven experiment. The critical ignition temperature of Korean pine sawdust was measured under the experimental conditions. The critical relationship between the accumulated size and ambient temperature was also given.
