The stretching term in the vorticitytransport equation is found to be the main mechanism to reduce the degree of mixing in axisymmetric plume.
从涡量输运方程出发，分析得出拉伸项的存在降低了轴对称热羽流的混合强度。

Since the disturbance expansion has been taken into account, one has to solve the mass, vorticitytransport and energy transport equations for disturbance motion in a coupled way.
