摘　　要：对不同基液制备的SiO_2纳米颗粒悬浮液稳定性进行了实验观察,并在此基础上,深入讨论了颗粒的当量直径、基液动力黏度等因素对悬浮液稳定性的影响,得到了一些有意义的结论。基液动力黏度对悬浮液的稳定性起决定性作用。The stability of nano-particle suspension is researched in the paper. Experiments are performed for the SiO2 nano-particle suspensions with different base fluids to observe their stability. On the basis of the experiment, the factors affecting the stability namely the equivalent diameter of the nano-particles and the dynamic viscosity of the base fluid are discussed and some valuable conclusions are obtained. It can be seen that the most important factor to affect the stability of nano-particle suspension is the dynamic viscosity.
