摘　　要：为了探究影响微胶囊相变悬浮液稳定性的因素,通过改变相变颗粒粒径以及基液,配制不同种类的微胶囊相变悬浮液.在实验基础上,建立数学模型,分析计算了影响其稳定性的各个因素及其所占权重.结果表明:在实验条件下,相变微胶囊颗粒的粒径以及基液的动力粘度对稳定性的影响有决定作用.In order to find the factors which significantly affect the stability of the microencapsulated phase change material slurry, by changing the base fluid and the size of phase change matedal, different types of phase change suspensions are prepared. Based on the experiment, mathematical model is established, and related factors which affect the stability of suspension were analyzed. The results show that under the experimental conditions, the particle size of the microencapslues and dynamic viscosity of the base fluid are the main factors which influence the stability of the microencapsulated phase change material slurry.
