The analysis reveals a relation between the Laplacian exponent and the regularity of the spaces of velocity and magnetic.  Moreover,  in the whole space $\mathbb{R}^3$, we establish the  algebraic decay rate of  solutions and higher-order derivative of solutions  for 3D generalized MHD system provided that the parameter $\alpha<\frac32$. 本年度学院报告总序号： 20
