The motion of each phase is described by a unified multi fluid model in an Eulerian coordinate system. The laws of turbulent transportation for each phase, and the restriction of each other between the two phases are completely simulated. The complex two phase turbulence with strong buoyancy effects is selected to examine numerically. The extensive experimental data obtained in stratified flow are used here. Comparison of the results of numerical simulation with the experimental data is conducted. It has shown that the results of numerical simulation are satisfactory.展开更多

Methods： Fifty male Wistar rats were divided randomly into 5 groups, control group, model group, drug group, moxibustion group, and laser group, 10 for each. Four groups except the normal group were built on the model of rheumatoid arthritis. The changes of body weight and plantar circumference were measured and the level of IL-1β, IL-2 in sera were examined by ELISA. Results： Compared with the model group, the weight and plantar circumference of rats in the moxibustion group were improved significantly after treatment （P〈0.01）, and the improvement of plantar circumference also had significant differences compared with the drug group and the laser group （P〈0.05）. The level of IL-1β, IL-2 in sera were down regulated in the moxibustion group and the laser group, which had statistical differences compared with the model group （P〈0.05）, but no statistical differences were found when comparing with the drug group. Conclusion： Moxibustion obviously improves the toe tumefaction of the rats with rheumatoid arthritis, which is better than CO2 laser of 10.6μm. On the aspect of decreasing the amount of IL-1β, IL-2, CO2 laser of 10.6μm is similar with moxibustion.展开更多
