| 摘 要： | 在介绍环己烷/PDMS体系中起泡脱挥气泡场的激光全息图记录与再现的基础上,对其全息图通过计算机进行了VPPSA颗粒分析和数据处理。讨论了液体深度、操作真空度和环己烷初始浓度对数均气泡直径的影响。结果表明,数均气泡直径随液体高度增加而增加,随操作真空度和环己烷初始浓度的增加而稍增大。液体深度是其主要影响因素。对测量误差的影响因素进行了讨论。

| Abstract: | On the basis of introduction to the hologram record and reconstruction, the analysis of particle hologram is carried out for the bubble fields of foam devolatilzation (foam DV) in cyclohexane/PDMS system. The effects of the operating vacuum, the initial cyclohexane concentration and the liquid height on the number average bubble sizes are discussed emphatically. The results show that the number average bubble sizes increase linearly with increasing liquid height, the operating vacuum and the initial cyclohexane concentration, but the liquid height is a key factor. The factors affecting the measurement error are also discussed. |
