1. If the satellite has an elliptical orbit, the result is a spiral wave, a miniature version of the pinwheel pattern of our galaxy.
   如果卫星的轨道是椭圆的，就会产生螺旋波，就像是银河系纸风车形状的缩影。
2. Another possibility is that large-scale spiral waves in the disk, similar to the spiral arms observed in galaxies, hasten the inflow of matter.
   另一个可能性是，类似星系旋臂的大尺度螺旋波，加剧了物质的向内流动。
