Several important properties of a kind of random symplectic matrix used by A.Bunse- Gerstner and V. Mehrmann are studied and the following results are obtained:
An analytical model of hydraulic damper was presented in forward flight accounting for pitch/flap/lag kinematic coupling and its nonlinear force-velocity curve.
A general method called time-shifting correcting method of phase difference on discrete spectrum is presented. That is, the second discrete-time sequence lags b
Without assuming the boundedness and differentiability of the nonlinearactivation functions, the new sufficient conditions of the existence and theglobal expone
