摘　　要：在具有自由面的旋转抛物面浅水中成功地观察到了涡旋的生成、漂移和演变过程,所有长寿命非扩展涡旋都是反气旋，不存在单个长寿命气旋涡,实验中还发现包含在涡中的粒子随涡一起运动，形成一种稳定结构。The formation' drifting and evolution of vortices have been successfully observed in a rotating paraboloid-shape shallotv water with a free surface. All long-lived nonspreadingvortices are anticyclones,and there is no long-lived single cyclone. It is also found that theparticles contained in the vortex drift together with the vortex,and a stable structure is formed.
