摘　　要：本文采用正交试验设计方法研究了pH值、超声振动时间、分散剂用量和磁力搅拌时间四个影响因素对Al2O3/乙二醇纳米流体悬浮稳定性的影响。取实验制备的Al2O3/乙二醇纳米流体的平均粒径和吸光度作为试验考查指标,得出最佳制备条件为:pH值为5、不添加分散剂、磁力搅拌时间为15 min、超声振动时间为5 h。The orthogonal test was used to study the effects on suspension stability ofAl2O3-EG nanofluid, such as pH value, ultrasonic vibration time, the dispersing agent and magnetic stirring time. The average particle size and absorbency were selected as indexes. The optimum process parameters are pH value of 5, not adding the dispersing agent, ultrasonic vibration time of 5 h, magnetic stirring time of 15 min.
