Chaotic Phenomena will occur in the dynamic system of the nonaxisymmetric Beltrami spherical vortices. From these aspects, it is shown that the tensor denotation has more meaningful characters and nonaxisymmetric Beltrami shperical vortices are various and very complex.展开更多
文摘Today is Thanksgiving Day in the U.S.People share a big meal with family and friends.The delicious smell of roast turkey fills the house.Corn,potatoes,sweet potatoes and green beans are on the table and ready to eat.There is cranberry sauce,too.Later there will be pumpkin pie!
文摘One kind of tensor denotation of nth Beltrami axisymmetric and nonaxisymmetric spherical vortices, their classification and symmetries were discussed. Chaotic Phenomena will occur in the dynamic system of the nonaxisymmetric Beltrami spherical vortices. From these aspects, it is shown that the tensor denotation has more meaningful characters and nonaxisymmetric Beltrami shperical vortices are various and very complex.
