摘要：

The response of a potentiometric sensor having a silver chloride layer interposed between the electronic conductor and the beta"-alumina electrolyte is analysed. The open-circuit voltage is found to be Nernstian in the range 10-10000 Pa of chlorine, with slight deviations from the theoretically expected values. The setting-up of a diffusion potential due to the formation of a new phase or a solid solution might account for these departures from theory. A normalized function of the output for step-like changes of chlorine pressure is defined. The approach to steady-state e.m.f. values is found to be linear with the square root of time.
