Based on linear instability method,the mathematical model coupled with multiparameter for jet stability is developed, which is used to study the instabilities of the compressible viscous liquid round jet in a compressible inviscid airsteam. The general analysis solutions of perturbed governing equations of the jets are obtained, and the general 3-dimensional disperse relation which delineates the evolution of the disturbance on the liquidgas interface is also derived. Finally, the numerical methods for the disperse relation is given.
