| 1. | In this paper , the analytical method of linear stability has been applied to establish the marginal stability criterion of natural convection in porous medium , after considering the action of gravity , centrifugal and coriolis forces together in centrifugal force field 理论研究的结果表明,当离心力与温度梯度同方向时,只要满足ra > 7 . 81 2或ra0 > 4 2 ,多孔介质中即可发生离心力、重力与哥氏力共同驱动的自然对流。 |
