摘要

聚并时间是研究气泡聚并行为过程中的一个重要参数。在消除气泡生长速度对聚并时间影响的条件下，利用自行开发的光学测试技术对双气泡间的聚并时间进行了精确的测量。考察了气泡尺寸、靠近速度、有机溶质的扩散、电解质和表面活性剂的加入对气泡聚并行为的影响。实验结果表明，双气泡间的聚并时间随着气泡直径的增加、气泡老化时间的延长、靠近速度的减小和有机溶质浓度的增大而增加。

Abstract

Bubble coalescence time is an important parameter in the study of coalescence behavior.By eliminating the influence of growth speed on coalescence time，a new laser detecting system was developed and used for precise measurement.The effects of bubble size，approaching velocity，diffusion of organic component and addition of electrolyte and surfactant on bubble coalescence were investigated.The result showed that bubble coalescence time would increase with increasing bubble size，delaying aging time，decreasing approaching velocity and increasing organic components concentration.
