Aiming at the shortcomings of the grounded resistances for measuring in three electrodes method,the authors convinced that the number of auxiliary current electrode could be increased and the grounded resistances measured by the multi electrodes.

Multi-current auxiliary electrode method that means arranging many current electrodes(C) around the grid (E) can mea.

Through a combination of upper and lower engines, the electrode current in the smelting process is controlled to achieve the purpose of controlling the temperature of smelting furnace.

It s very important to control the electrode current of arc furnace.

Study of polarization and depolarization current measurements for assessment of aging state of oil-paper insulated transformers

45 mm) on polarization potentials, polarization current and pH value in crevice were investigated.

Way of analyzing anode current state of thyristor;

Experiments point out: the neutron yield and its stability of a MTZ-54 neutron tube come to their top when the anode current of the tube is within a certain region;and the filament voltage/current need to be decreased gradually for keeping anode current stable while environmental temperature increases gradually.

Designed a set of system used to test the performance of limiting current type oxygen sensor.

Compared with existing limiting current oxygen sensors, it has a simpler design, a faster response and lower cost, thus has a good application.

A dense diffusion barrier limiting current hydrogen sensor was developed,with BaCe0.
