摘要：
Dust charging in the sheath is investigated with the single dust model. The sheath profile and variation of dust charge are revealed under the effect of ion temperature. It is shown that the dust particles are rapidly positively charged in the pure ion sheath near the wall and that the ion motion effectively shifts the zero-point of the dust charge to the wall.
