摘　　要：关于乳化油的微爆在以往的文献中提出过各种计算模型 ,对油包水与水包油两种乳化油的微爆有不同看法。提出一种油包水与水包油微爆的统一模型并给出了微爆强度的定义 ,试图对微爆的强弱做定量的描述。通过该模型讨论了一些主要因素 ,如液滴初始直径、分散相直径及水含量等对微爆强度的影响规律。计算结果表明 ,该模型的理论预测与实验事实基本一致。另外还讨论了其他因素如添加剂的性质、气体溶解度等的作用。An general model of the micro explosion of emulsified droplets,suitable for oil in water(O/W) and water in oil(W/O) is presented.Using this new model,a definition of micro explosion strength is proposed,also the effects of various parameters on micro explosion strength are discussed.Although emulsified oils have two different structures and different processes of forming an oil membrane,the definition of micro explosion strength and its calculation are identical in the general model.The results show that the predictions of the general model agree with experiments.Furthermore,some extra effects,such as the properties of a surfactant,the solubility of a gas and the deformation of a droplet under an aerodynamic force are also discussed.
