Initial and Boundary Value Problems for Two-Dimensional Non-hydrostatic Boussinesq Equations 总被引:3,自引:0,他引:3
Based on the theory of stratification, the weU-posedness of the initial and boundary value problems for the system of twodimensional non-hydrostatic Boussinesq equations was discussed. The sufficient and necessary conditions of the existence and uniqueness for the solution of the equations were given for some representative initial and boundary value problems. Several special cases were discussed. 相似文献

It is proved that the ill-posed initial value problem of the Euler equations for compressible adiabatic inviscid fluid flow can be only formally solved. The necessary and sufficient conditions for existence of formal solution of some representative ill-posedness initial-boundary value problem are presented. Finally, an example is also given. 相似文献

河北省中考理科综合的试题改革已持续了两年,其目的是要从多层面考查学生能力、培养有创新思维的人才,同时也是为逐步改变传统封闭的单一学科教学模式,使教学活动在更大的空间进行,并逐步造就一批具有全新教学观念和综合素质的教师队伍。今年中考理科综合试题的改革将进一步深化,物理部分、化学部分各减5分,综合部分的分值由20分增加到30分,这无疑是一个令师生瞩目的变化。 相似文献
