中文摘要：

利用显微摄像技术及算术统计的方法表征了甲醇乳化柴油分散相-甲醇的平均粒径。研究了甲醇乳化柴油分散相（甲醇）的粒径分布随高速分散器转子转速、乳化时间、乳化剂用量和甲醇的质量分数等参数的变化。结果表明,甲醇乳化柴油分散相的平均粒径随转速、乳化剂用量的增加而减小,但随甲醇含量的增加而增大;当乳化时间为2m in和转子转速为5×2800r/min,乳化剂的质量分数为5%和甲醇的质量分数为10%时,甲醇乳化柴油中分散相存在最佳的分散度,其值为16μm。

英文摘要：

The disperse phase（methanol） droplet size of emulsified fuel has a significant effects on the combustion methanol-diesel oil emulsified fuel.The methanol droplet sauter mean diameter in methanol-diesel oil emulsified fuel was characterized with microphotography and arithmetic statistic method.Effects of rotor speed of disperser,emulsified time,additive amount and methanol content on the dispersity characteristics were investigated.The experimental results showed that the disperse phase（methanol） droplet size of emulsified fuel decreased with the augment of the rotor speed and additive amount,and almost contrary to the methanol content.The disperse becomes much better when emulsified time is 2min,rotor speed is 5×2800r/min,additive amount is 5% and methanol content is 10%,whose mean diameter is 16μm under experimental condition.
