Perturbationtheory indicates that smallperturbation of the coefficients could lead to the big perturbation of the root.
摄动理论显示,对于特征方程系数的小幅度扰动即可导致根的大幅度变化。

Using two-flow model, smallperturbationtheory and solvable conditions of one-order linear equations, a dispersion equation of pressure wave in horizontal air-liquid bubbly flow was proposed.
