您要查找的是不是：
- periodic spiral wave 周期螺旋波
- Angular Momentum Transports by Moving Spiral Waves. 移动螺旋波角动量传输。
- 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。
- Results:At present mechanism of atrial fibrillation is mostly the multiple wavelet bypothesis and spiral wave bypothesis and so on. 结果:目前认为房颤的发生机制主要是多发微折返环学说和自旋波折返学说等。
- Just as sound waves transport energy through the air, spiral waves can transport both energy and angular momentum outward and facilitate the accretion of material inward. 就像声波在空气中传播能量，螺旋波可向外传递能量与角动量，使物质易于向内累积。
- Suppression of a Spiral Wave Using Linear Feedback 线性反馈抑制螺旋波
- 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。
- But the spiral waves in these systems do not appear to be large enough to produce the rate of matter inflow needed to explain the observed radiation from the disks. 但是这些系统中的螺旋波似乎还不够大，其所造成物质的向内流量，不足以解释观测到的圆盘辐射。
- In the numerical experiment,we successfully alter the propagating direction of planar waves and drift the spiral waves to boundary without resonant repulsion. 结果表明:行波的传播方向被改变而螺旋波产生漂移,当施加的控制强度达到阈值时,螺旋波被驱除出边界。
