【 摘 要 】

Charge generation due to friction between stainless steel and fused quartz in a vacuum was measured, and it was found that the density of the charge separation at the friction contact was 4×10-4C/m2In experiments in ambient gas, reduction of the separated charge caused by microgap gas discharge was observed. The residual rate of the charge, which is the ratio of charge accumulation in an ambient gas to that in a vacuum, in argon ambient gas was small, and it seemed to be effective for the relaxation of generated static electricity due to friction between solids.
