摘要：

For a high negative voltage V0 placed impulsively at the edge of a plasma, a sheath is formed of thickness X = (2eVo) 1/2(4πnie2)-1/2 This sheath is observed by extrapolating the position of the leading edge of an ionic sound-wave pulse back to zero time. The ion number density can be obtained from this sheath.
