SV波的传播时间也可用三项泰勒展式表达，在中等及短排列长度时可达到一定精度。
For the P-SV wave travel time, it also can be expressed exactly by a three-term Taylor series in short or moderate spreads.
应用简正波传播时间与声速起伏的对应微扰关系式，给出了上述对应关系的理论解释。
The relation equations between Normal Mode propagation travel-time and sound-speed fluctuation are used to explain the qualitatively relationship between two spectra.
