| 摘要: |
| 从描述颗粒流动的推广BGK模型方程出发建立颗粒流方程。其中推广BGK模型方程的处理采用了经典分子动力论中的Chapman-Enskog方法。由于建立颗粒流方程的思路简单清晰，且方程中各量都有明确的物理意义，因此易于推广。 |

| Abstract: |
| The granule flow equations are deduced from the generalized BGK model. The generalized BGK equation is treated with the Chapman-Enskog method that is used in the classic molecular kinetics. The equations are easily generalized since the method is simple and the quantities in them have concise physical meaning. |
