对电外科手术过程中有源电极与生物组织之间产生的火花的电特性进行了实验研究。结果表明，引发火花所需的最小电压取决于所施加的电压极性，从而导致电外科电压不对称。这种电压不对称能够产生直流电平，这可能导致组织电刺激或直流电烧伤，如本文所讨论的。的实验装置和条件下，已获得的结果，包括用于提高实验重现性的技术，详细报告。
The electrical characteristics of the sparks produced between the active electrode and the biological tissue during electrosurgical procedures have been experimentally investigated. The results have shown that the minimum voltage required to initiate a spark depends on the applied voltage polarity resulting in electrosurgical voltage asymmetry. This voltage asymmetry is capable of producing dc levels that can result in tissue electrostimulation or direct current burns as discussed in this paper. The experimental setup and the conditions, under which the results have been obtained, including the techniques used to improve experimental reproducibility, are reported in detail.
