用两种不同的方法求解动力学方程，重新讨论了测地线声模的色散问题。计算了模态频率的色散修正量，包括了2个极向谐波。我们得到的结果与先前的一些结果一致，但在许多方面与其他先前的工作不同。讨论了不同方法的局限性和优点。
The problem of dispersion of geodesic acoustic modes is revisited with two different methods for the solution of the kinetic equation. The dispersive corrections to the mode frequency are calculated by including them= 2 poloidal harmonics. Our obtained results agree with some earlier results but differ in various ways with other previous works. Limitations and advantages of different approaches are discussed.
