摘要
以微积分为工具讨论了具有连续变量的非线性差分系统的稳定性和振动性，给出了系统稳定的新判据和系统振动的充分必要条件及线性系统存在非振动解的充分必要条件。
The stability and oscillation characteristics with continuous variables are discussed by using differential-integral method. A new criterion for the system stability is proposed. The conditions for both system oscillation and non-oscillation solution of the linear system are given.
