A class of perturbed discrete nonlinear Schrödinger equations with sublinear terms is studied. The new features are: (1) negative and positive energy homoclinic solutions are obtained; (2) the continuity of solutions in the perturbed terms at zero is studied; (3) the positive-definite condition can be removed.

具有摄动和亚线性项的离散Schrödinger方程的多重同宿解。

研究了一类带有亚线性项的摄动离散非线性薛定ding方程。新的特点是：（1）获得了负能量和正能量同斜解；（2）研究了扰动项为零时解的连续性；（3）可以消除正定条件。
