The mechanism and the course of two-dimensional nonlinear dynamic system ofinterspecific interaction were dealt with systematically. By extending the Lotka-Volt
A family of integrable systems of Liouville are obtained by Tu pattern. Using higher-order potential-eigenfunction constraints, the integrable systems are facto
The influence of labyrinth seal on the stability of unbalanced rotor system was presented. Under the periodic excitation of rotor unbalance, the whirling vibrat
The principal resonance of a visco-elastic systems under both deterministic and random parametric excitation was investigated. The method of multiple scales was
Based on the strain formulation of the quasi-conforming finite element,displacement finctions are constructed which have definite physical meaning, and a conclu
