摘要：

The use of a scanning electron microscope to examine the tracks left on cathode electrodes by arcs moving with a high transverse velocity has enabled estimates to be made of the sum area of coexisting emission sites. Correlation of such areas with the instantaneous values of arc current leads to current density values in the range 1-50 MA cm-2, in agreement with results of other recent investigations.
