摘　　要：将粉体接触角测量技术用于河口界面化学的研究,测定了长江口地区9个站位表层底泥的润湿性,从润湿性角度探讨了长江口表层底泥的表面状态。The estuarine interface chemistry of fine paniculate sands from the sediments of the Changjiang River Estuary was studied by the Contact Angle of Powder. The wettabilities of nine sediments in the Changjiang River Estuary were determined and the surface states of them were discussed. This new type of method for the studying of estuarine interface chemistry, which was named Contact Angle of Powder, has not yet been reported before.
