综合治疗烧伤时在创面区的不同部位放置异质金属片,此金属片不须外电源便能在生物系统内引发定向性电动势产生有临床意义的电流。作者利用可形成低度或中度氧化物的金属或合金作为阳级——供给电子,在锌、铝和某些其他金属的底层上复有氧化膜的特殊合金作阴极——接收电子,就能产 Comprehensive treatment of burn wounds in different parts of the wound area to place heterogeneous metal sheet, the metal sheet without external power can be induced in the biological system of directional electromotive force to produce a clinical significance of the current. The authors use a metal or alloy that can form low or moderate oxides as a positive-electron-donating electron, and a special alloy that has an oxide film on the underlying layers of zinc, aluminum, and some other metals for cathode-receiving electrons. Can produce
