摘要:本研究通过考察卷烟纸定量、透气度、助燃剂镁盐含量以及助燃剂中钾盐占比等对中支卷烟燃烧锥落头倾向的影响，并结合正交实验设计分析各参数对燃烧锥落头倾向的影响程度，最终选用针叶木与阔叶木纤维配比30∶70，碳酸钙含量为28%，柠檬酸钾、苹果酸钾和柠檬酸钠助燃剂复配，助燃剂钠钾比为1∶1.2、含量（柠檬酸根计）1.5%的设计方案进行优化，卷烟燃烧锥落头率从11.25%下降至3.75%。

Abstract:This study investigated the effects of cigarette paper quantity， air permeability， magnesium salt content of combustion aids， and the proportion of potassium salt in combustion aids on the fallout propensity of combustion coal during the static combustion of medium cigarettes. Combined with orthogonal experimental design， the degree of influence of various parameters on the fallout propensity of combustion coal during the static combustion was analyzed. Finally， a ratio of 30 soft wood to 70 hardwood fibers was selected， with a calcium carbonate content of 28%， and a combination of potassium citrate， potassium malate， and sodium citrate combustion aids， the design scheme with a sodium potassium ratio of 1∶1.2 and content of 1.5% （calculated by citrate） as the combustion aid was optimized， resulting in a decrease in the dropping rate of the combustion coal from 11.25% to 3.75%.
