摘　　要：本文用^(31)P-NMP研究了二烷基二硫代磷酸锌(ZDP)在内燃机基础油体系中的作用,发现在低浓度下从ZDP解离出一个含磷核的组份,化学位移为86ppm。表明ZDP在油中的溶解存在着依赖于浓度的化学平衡,通过这种平衡解离在ZDP与分散剂体系中的变化,研究了添加剂间的相互作用机理。The system of zinc dialkyldithiophosphate(ZDP) in lubricating base oil has been studiedby using ^(31)P-NMR. At low concentration of ZDP a phosphorated compound resonatingat chemical shift of 86ppm was found. This indicates that there exists a chemical equilibri-um which is related to ZDP dissociation in the base oil and depends on the concentration ofZDP. A mechanism was proposed about the interaction between ZDP and succinimide dispersant.
