| 摘 要： | 为了避开旧物质臂理论中旋臂的缠绕困难，本文提出了旋涡星系的循环假设，并提供了旋涡星系的双臂、气体层反卷、银河系中旋臂物质径向向内的速度分量和棒旋星系中棒物质沿着棒向内的流动等观测证据。进而还尝试利用此循环假设去解释旋臂物质的平自转曲线和棒旋星系的棒结构等的成因。

| Abstract: | For the purpose of avoidance of the winding dilemma of spiral arms in thematter arm theory,a circulation hypothesis of spiral galaxies is proposed. Such Proof as two-armed spiral pattern,warp,an inward radial component of the velocity of the spiral arm inthe Milky Way and the inward flow of the gases along the bar in a barred spiral galaxy aregiven in this paper. The origin of such observed phenomena as the flat rotation curve of spiralgalaxies and the bar structure in a brred spiral galaxy is explained on the basis of the circulation hypothesis. |
