AIR CUSHION SEISMIC VIBRATOR |
摘要 |
A seismic vibrator is designed for use over all kinds of terrain including marshy areas where conventional land or sea vibrators cannot be used. The vibrator is an air cushion vehicle modified by the addition of an air flow modulator which pressure modulates the air cushion. The pressure modulations are passed on to the material beneath the vehicle.
