The analyzed and contrasted results of the distribution of the surface pressure distributions and the sectional side forces with the former results of the slender body in the same flow conditions show that the shm ' s control effect to the slender body is due to that the two asymmetric vortices over the slender body model are sensitive to the nose perturbations 通过对物面压力分布、截面侧向力分布和以前细长旋成体结果的对比和分析，发现单孔位微吹气扰动对于细长旋成体横侧向控制作用在于模型头部背风侧非对称二涡结构对扰动的敏感性。
