    摘要: A process for treating a biological or synthetic object subjected to an electrical field in a surrounding liquid medium for a predetermined pulse time (t1), the electrical field being formed by at least two electrodes including actuating at least once during the pulse time (t1) each of the electrodes as an anode and as a cathode, to cause at each electrode a polarity reversal and alternating electrolytic increases and reductions in pH of at least a portion of the liquid medium, subjecting the object during the pulse time (t1) to a number of electrical partial pulses which have a frequency in the range of 1 kHz to 1 MHz and which possess partial pulse durations, with sequentially reversing polarity or field direction such that the partial pulses possess sequentially varying partial pulse durations (t11, t12), pulse forms, and/or pulse amplitudes, and selecting the partial pulse durations (t11, t12), pulse forms, and/or pulse amplitudes such that, due to the electrolytic increases and reductions in pH value, substantially equal H+ and OH− ion concentrations are created.

    摘要: In a method for positioning or controlling the motion of an object in a multi-electrode arrangement for forming a field cage, the basic potentials for driving the electrodes are modulated with drive potentials in such a way that the object position in the field cage changes in relation to a predetermined position or path. A device for arranging objects at predetermined positions in a multi-electrode arrangement has a switching device by which basic potentials, produced by generator means, can be modulated according to predetermined drive potentials (FIG. 1).
