摘要：We consider a perturbative, one-dimensional,  quasi-periodic, linear KdV 

equation with periodic boundary condition Under the real analyticity and 

reversibility assumptions of the coefficients, we  show that there 

exists a Cantor set in the frequency space of almost full measure such 

that for each frequency vector in the space, the corresponding equation 

is smoothly reducible to a constant-coefficients one. This problem is 

closely related to the existence and linear stability of quasi-periodic 

solutions in a nonlinear KdV equation.
