原太阳吸积盘为冷的薄盘,盘中热对流不稳定性由外而内,由上而下地终结;
For the cold protosolar accretion disc, convective instability will gradually end from the outer region to the center and from the surface to central plane.
高频不稳定性使室壁对流传热系数大大增加。
High frequency instabilities result in grossly increased convective heat transfer coefficients in the chamber walls.
着重研究了径向粘滞力对含径向对流吸积盘的径向-环向不稳定性的影响。
We find that the introduction of radial viscous force have no influence on stability of viscous and thermal modes, but more influence on the stability of acoustic modes.
以上这些大气层中,只有对流层(尤其是边界层)中气象参数的垂直分布具有显著的不稳定性的特征。
Of all the above atmospheric layers, only the troposphere (especially its boundary layer) is characterized by a marked instability of the vertical distribution of the meteorological parameters.
