摘　　要：研究一类带黏性项、零扩散广义Boussinesq方程组局部解的存在性问题,应用正则化方法、压缩映像原理以及经典的能量估计方法,证明了带黏性项、零扩散的广义Boussinesq方程组解的局部存在性,应用Sobolev不等式获得解的一个爆破准则。研究结果能揭示一类特殊流体运动的物理现象,能更精确地反应流体的运动情况。A kind of adhesive, zero spread of the existence of the generalized local solution Boussinesq equations is considered. Using the regularization method, the compression mapping principle and the classical energy estimation method, the adhesive, zero spread of the local existence of the generalized Boussinesq equations are derived. And using the technique of Sobolev inequality, a blasting principles is obtained. The results of the study reveals a kind of special physical phenomenon of ?uid movement.
