摘　　要：离子对其周围水分子的取向极化作用能，与离子的带电荷数成线性关系，而与离子半径和离子电荷的正负性无关，离子周围只能排引１层定向水分子。带电荷数为１的离子，与周围水分子的取向极化作用能是：１０１８，４２ＫＪ／ｍｏｌ。The relation is linear between water directional polarization energy and chargenumber of ion. The energy is not refated to the ion radius and ion quality,and there is on-ly one directional water layer near the ion surface. The water directional polarizition ener-gy is l0l8.42 KJ/mol when the charge number of ion is one.
