| 摘 要： | 本文提出了光滑管内湍流自由旋流旋流数ＳＷ沿轴向衰减规律的近似解。Ｓｗ的衰减与雷诺数Ｒｅ有关，Ｒｅ越小，其衰减的速度越快。增加Ｒｅ可延缓Ｓｗ的衰减。

| Abstract: | In this paper,the attenuation of turbulent sirl flow in the smooth pipes has been studied theoretically. The attenuation has a direct beering on the Re numbers. When the Re numbers are small,the rate of attenuation are so rapidly. With the Re numbers increase,the attenuation of swirl numbers are dropped. |
