关于喝酒的诗句摘要：Laboratory experiments were conducted to study the motion of miscible buoyant fluid parcels in both homogeneous and stratified media, and were complemented with numerical experiments using the model of Orlanski & Ross (1973). Parcel motion in the homogeneous ca was found to be shape-prerving, in agreement with the large body of data for such motion. The stratified medium experiments were such that the parcel attained equilibrium positions. It was found that the time for the parcel to reach maximum depth was approximately 0·7 times the buoyancy period, independent of that depth. The subquent collap of the parcel and generation of internal gravity waves was obrved. Ray-like patterns of waves propagated out from the collap region, and wave frequencies near 0·7 times the Brunt-Visl frequency were predominant. The 第三人
