The results show that after triggering discharge, the wall charges can be varied by adjusting the driving waveform, and the high wall voltage can be obtained.

The unsteady wind tunnel wall pressure for two groups of models oscillating in pitch to high angles of attack was measured.

The pressure experiment results of two sets of models with large blockage have been corrected with the wall pressure signature correction method developed by the author of this paper,which takes account of the axial translation acceleration effect of wall blockage interference.

When testing,free-field pressure and wall pressure were measured.

The first method calculated the interstage coupling coefficient by adding the electric wall and magnetic wall in the symmetry plan and calculated their resonant frequency.

For water-uncouple charge,detonation wave shocks and presses water and stimulates shock wave,transmitting blasting pressure to rock through water and so its pressure of bore wall descended;for air-uncouple charge,however,products of detonation swelled and filled whole bore and then effects bore wall and its pressure of bore wall is the smallest among the three condit.
