| 摘 要： | 依据流体动力学理论分析了低雷诺数风流中瓦斯上浮现象的特性和机理，实验研究，得出在低雷诺数风流中集中涌出瓦斯的上浮运动和浓度分布，瓦斯在风流中有向前和向上两这移过程，向前运移与风流携带引起的对流扩散，而向上运移是体积力引起的浮升运动。

| Abstract: | The feature and Mechanism of methane buoyant phenomenon is analyzed by theory of liquid dynamics in the airflow of low Reynolds number. The buoyant movement and the concentration distributions of methane is obtained by means of experiment in the airflow of low Reynolds number. There are forward and upward migaration processes of methane, the first process is convection confusion by the action of airflow, the second is buoyant movement by volume force. |
