Based on this expression, the inherert law of differences between expo-nents of driven points from the same drive pair and the same driving point and of correspordingdriving points A method for finding out the exponents of the range ratio hat been given accordingto the law and it is called coordinate diagram method. Finally, a mathematical model is constiuctedand a computer programme is designed.展开更多

Mixing model has been used in data reduction,the horizontal miring coefficients of particles in different experimental conditions and in different structures of dense bed have been obtained and compared. By using dimensional analysis, non-dimensionalexpression of experimental condition and mixing coefficient have been obtained.展开更多
