利用和达法和石川法对宁波皎口地震的资料进行处理，得到了各台站１９９３年和１９９４～１９９５年初两个时间段内的虚波速度和多台平均波速比。并得出如下结论：（１）樟水流动台１９９３年虚波速度值异常高，这主要是因为地震波特殊的传播路径以及传播介质在应力积累时产生大量微裂隙引起；而１９９４年后又呈大幅下降则主要是由于介质裂隙大量充水饱和后引起。（２）与樟水台同处近场的洪山和雪山两个流动台的虚波速度１９９３年虽也处于较高值，但与樟水台相比却明显要低，这是由于介质波速异常的方向性效应引起。（３）近场虚波速度明显高于远场虚波速度，多台波速比在４７级地震前处于中长期低值异常，而地震后回归正常。（４）近场速度特征可作为一项地震预报的追踪指标在皎口地震中应用，但还需进一步完善。
The data of Ningbo Jiao Kou earthquake are processed by using the method of Heida and Ishikawa, and the velocities and multiple wave velocities of each station in 1993 and 1994 ~ 1995 are obtained. The conclusions are drawn as follows: (1) The amplitude of the virtual wave velocity in the camphor flow station was abnormally high in 1993, mainly due to the special propagation path of the seismic wave and the large number of micro-fractures in the propagation medium in the stress accumulation. Substantial decline is mainly due to a large number of saturated water caused by media fissures. (2) Although the velocities of the two mobile stations in Hongshan and Snow Mountain in the near field with Zhangshoutai are higher at 1993, they are obviously lower than that of Zhangshui station, which is due to the abnormal wave velocity Caused by the directional effect. (3) The near-field wave velocity is obviously higher than the far-field wave velocity, and the multi-wave velocity ratio is in the mid- and long-term low anomalies before the 4.74 earthquakes, and returns to normal after the earthquake. (4) The near-field velocity feature can be used as a seismic tracking indicator in the Jiaokou earthquake, but it needs to be further improved.
