中文摘要：

为了研究三相泡沫的流体特性，采用实验的方法，考察了剪切速率、发泡倍数、温度、气体介质对三相泡沫粘度的影响，构建了三相泡沫流体的本构方程，测定了三相泡沫流体在注浆管路中的流动阻力及管压降。研究结果表明：三相泡沫属于假塑性的非牛顿流体，其粘度与发泡倍数和温度有关，而与气体介质无关：在一定的条件下，每100m管路中三相泡沫的压力降为0.18MPa。研究结论为三相泡沫在现场的应用提供了依据。

英文摘要：

In order to study the rheological properties of three-phase foam, experiments were conducted to research the factors influencing its viscidity in relation to shear rate, expansion of foam, temperature and gaseous medium, and a rbeological expression of three-phase foam is set up according to these parameters and its flowing resistance and reduction of pressure is measured in the pipeline. The results show that three-phase foam exhibits non-Newtonian behaviour and a characteristic of pseudo-plastic material. Its viscidity is related to foam expansion and temperature and is not influenced by gas medium. Under certain condition, the reduction of pressure in the pipeline of three-phase foam per 100 meters is 0.18MPa. The conclusion provides basis for the application of three-phase foam in coal mine.
