摘要：
The ignition of spark gaps for the production of shockwaves in the contactless comminution of concrements, using a capacitor discharge is improved by providing at least for some time prior to the ignition proper a voltage much smaller than the breakthrough voltage for producing a small current between the electrodes that prepares a channel in the discharge gap.
