讨论了人工粘性、网格密度对计算结果的影响：较大的人工粘性系数和较粗的网格会严重抹平冲击波峰值压力，但对冲量影响较小。

Based on the analysis of the single-ring resonator, both the transfer functions of parallel-coupled structure and the ones of series-parallel structure in multiple-ring high order resonators are derived using the transfer matrix method. And the influences of the length of straight waveguide between rings, coupling coefficients between rings, coupling coefficient between straight waveguides and ring, the number of rings and the radii of rings on spectral response are also analyzed. Spectral response at drop channel with maximally flat response pass bands and sharper roll-off could be achieved by optimizing these parameters, so as to improve the performance of output spectral response.
