摘要：

The stability problem for the so-called continuous-discrete solitons in a nonlinear fiber array is examined. We prove that the ground states are unstable if the first derivative of the ''energy'' integral P = Sigma(n) integral\Psi(n)\(2)dt with respect to the soliton parameter lambda(2) is negative.
