摘　　要：应用SX2-10-13型马弗炉和电炉对黑龙江省主要草本可燃物灰分含量及燃烧速度进行了测定,分析了不同草本可燃物、同一科草本可燃物及科与科之间灰分含量及燃烧速度的差异,以及产生差异的原因。从灰分含量及燃烧速度综合分析得出,灰菜的灰分含量(25.48%)为20种草本可燃物中最高,其燃烧速度(0.723 4 s)为20种草本可燃物最慢,说明其阻火性能为20中草本可燃物最好;而唐松草的阻火性能最差,其灰分含量(4.85%)为20种草本可燃物中最低,燃烧速度(0.113 5 s)为20种草本可燃物最快;草本可燃物科与科之间灰分含量与燃烧速度比较分析得出,草本可燃物科与科之间灰分含量与燃烧速度没有固定的规律;草本可燃物灰分含量与燃烧速度的负相关。An experiment was conducted to measure ash content and combustion velocity of main herbal species in Heilongjiang Province by using SX2-10-13 muffle furnace and electric oven.The differences of ash content and combustion velocity among different herbal species fuels,among the herb inflammable matters within the same family and the plant fuels among different families were investigated respectively,as well as the causes of leading the differences.The results of comprehensive analysis of the ash content and the combustion velocity show that among the 20 herbal species,the ash content(25.48%) of Chenopodium album L.was the highest but its combustion velocity(0.723 4 s) was the slowest,its fire resistance was the best of the 20 herbal fuels;and the Thalictrum aquilegifolium L.var.sibiricum Regel was the worst fire resistance herbal species,its ash content(4.85%) was the lowest,and its combustion velocity(0.113 5 s) was the fastest of all the herbal fuels.The analyses results of the herbs fuels ash content and the combustion velocity between the different branches of the herbal species show that there was no fixed rule between the herbs fuels ash content and combustion velocity,but there was a negative correlation between the ash content and the combustion velocity.
