摘要： A method for underwater exploration which makes use of a parabolic transmitter (1) and a parabolic receiver (3), the transmitter (1) and the receiver (3) being both open at their lower side and immersed below the seawater surface. The electric breakdown discharge occurring between both electrodes (15) of the transmitter (1) generates a primary signal and a pulse which is called “cavitation bubble pulse.” The method consists in enhancing the signal (23) produced by the implosion of the cavitation bubble, to the detriment of the primary signal (13″), by appropriately adjusting the value of the “spark gap” (distance d between the electrodes) so as to optimize the delay time (t) and consequently the acoustic efficiency of the transmitter, by transferring the electrostatic energy to the bubble implosion signal.

摘要： Water is treated with sound waves produced by means of a submerged plasma sparking device (16) to mitigate detrimental effects of aquatic organisms in the water. For example, the incrustation of zebra mussels may be reduced by killing the zebra mussels or creating an environment hostile to them. The plasma sparking device may have a main storage circuit (14) which includes liquid dielectric capacitors or cryogenically cooled field coils for storage. Moreover, the electrodes (50) of the plasma sparking device may be of aluminum or an aluminum alloy.

摘要： A spark discharge acoustic pulse transducer for borehole operation provides an insulating ceramic barrier which contains a small cross-section aperture separating two bodies of electrolyte through which the two zones of liquid make contact. An electrical arc discharge is caused to occur through the aperture to produce a transient pressure pulse and associated acoustic pulse which is coupled to the geologic formation at the borehole wall. The specific shape and geometry of the aperture channel in the insulating barrier being exponentially shaped provides a means for controlling the waveform and frequency spectrum of the acoustic pulse. The transducer has an elastic outer housing and an elastic inner housing with hydraulic fluid between the inner and outer housings. The pressure of the hydraulic fluid may be increased to expand the outer housing against a borehold prior to a spark discharge. The transducer is also provided with a system for venting gas produced as a result of the spark discharge. The transducer is designed to produce asymmetrical forces on the borehole wall in the azimuthal plane about the discharge chamber axis.
