摘　　要：指出Debye-H櫣ckel离子活度系数公式中,除了静电作用项以外还有另一项,称之为渗透项.渗透项鲜为人知,故着重讨论该项的意义和作用.It was pointed out that two terms should be contained in the ion activity coefficient expression in the frame of Debye-Hiackel theory, i.e. the electrostatic term and osmotic term. Particular attention has been paid to explorations for the meaning and role of the osmotic term in the theory of ionic solutions.

关 键 词：离子活度系数 静电作用项 渗透项
