摘　　要：考虑一类耦合含梯度项的退化抛物方程组的近似可控性.当控制函数只作用在一个方程上时,利用对偶方程组的唯一延拓性证明该方程组的近似可控性.The author considered the approximate controllability o f a class of coupled degenerate parabolic equations with the gradient terms.Whe n the control function only acted on one equation,the author proved the approxi mate controllability of the equation by using the unique continuation of the adjoint equations.

关 键 词：退化抛物方程 近似可控性 耦合方程组
