摘　　要：从封孔剂试验结果得知，在封孔过程中氟离子浓度变化可显著地影响水化、络合和沉积反应，从理论上探讨镍氟体系封孔剂氟的作用机理，并提出改善封孔效果的措施。The reaction of hydration, complexation and sedimentation were remarkably influencedby the exchange of fluorine ion concentration in sealing. According to the resultS of sealing test, themechanism of action of fluorine in Nichel--Fluorine system sealing agent is discussed, the methods toimprove the sealing effect are given as well.
