The effed Of three-dimensional perturbed velocities and three-dimensional perturbed current densities on the beam-wave interaction of plasma-filled dielectric Cherenkov maser is analysed by use of the self-consistent linear field theory without considering the effect Of the longitudinal guided magnetic field.The dispersion relation and the Simultaneous condition of the beam-wave interaction are derived. It is clearly shown that the instability of the interaction results from the coupling of the TM mode in t...

A cusp catastrophe model is presented to describe the behavior of sliding along one deep incompetent structural plane of a gravity dam foundation, and the sufficient conditions leading to instability are discussed. It is found that the instability of sliding relies mainly on the stiffness ratio k, the homogeneity index of the medium m and the geometry-mechanic parameter ξ and that the reliability of the traditional limit analysis method is deficient.
