昭和58年4月日本久慈市的林野发生火灾,火灾消灭后,经过八天又发生再燃,消防队对这种残火的处理感到很恼火。腐殖质土的着火,与吸烟、焚烧或飞火有着密切的关系。为此研究与实验腐殖质土壤的着火温度,具有一定的实际意义。 In April, 1958, a fire broke out in Linye, Kuhcity City, Japan. After the fire broke out, it rekindled after eight days and the fire brigade was very angry about the treatment of this residue. The humus soil fire, and smoking, burning or fly fire has a close relationship. Therefore, it is of practical significance to study and test the ignition temperature of humus soil.
