The linear time perturbation theory is used in this paper, the effects of rotary flow, axial flow and both of them to the arc stability are discussed respectively.
The compressible linear stabilitytheory and the method of multiple scales are used to study the problem of three dimensional nonparallel flowstability for boundary layers.

A theoretical analysis is made, by applying linear stabilitytheory, orl the model of gas-liquid stratified flow.
