Research results of C atomicity in paraffin hydrocarbons show the linear paraffin hydrocarbons （from Tetradecane to Heptadecane） are almost burned up at lower loads, and some components of the SOF are not directly from fuel, but from lubricant oil or middle polymerization products of fuel.

SOF烷烃碳原子数分布的研究表明，低负荷工况下，燃油中易燃的正十四烷～正十七烷的绝大部分被烧掉，SOF中有些成分不是直接来自燃油，而是来自润滑油或燃油聚合反应的中间产物：高负荷工况下，供油量较多导致一部分正十四烷～正十七烷来不及燃烧就排出机外，SOF中还有些成分则是燃油高温裂解的产物。

The current theory and application of Al-Si alloy mainly focus on the study of hypoeutectic and eutectic, therefore we systematically analyzed the modification process of hypereutectic Al-Si alloy based on the methods and results of predecessors. Several factors including the modification temperature, the content of modifier, the available holding time, the times of repeat melting , the casting temperature and the speed for cooling have been studied in order to understand its effects to the composition, function and performances of primary silicon and eutectic silicon.

中文摘要本文针对目前Al-Si合金相关应用和理论的研究多集中于亚共晶和共晶合金的情况，在前人的研究成果和研究方法的基础上，对过共晶Al-Si合金变质处理进行了较为系统的分析，研究了变质剂的成分配比、变质温度、变质剂的加入量、变质后的静置时间、浇注温度及冷却速度等因素对过共晶铝硅合金中初晶硅和共晶硅的大小、形状、数量和分布的影响。
