The uniformed design of experiment is used and the sas of software was adopted to analyze the result in order to discuss that other additives affect the tribological behaviors of tbp and tpp in the rapeseed oil . it has been found that both tbp and tpp as additives increase the load - carrying capacity and antiwear ability of the vegetable oil . and the tribological model can effectively forecasts the results of the objects so it is help to cut the costs . in addition to other additives have the capcity to affect the tribological behaviors of tbp and tpp 利用四球机考察了磷酸三丁脂( tbp )和磷酸三苯脂( tpp )作为植物油添加剂的摩擦学性能；应用bp神经网络建立了tpp在菜籽油中的摩擦学模型；用均匀设计组织试验， sas统计软件分析处理数据，探讨其它添加剂对tbp和tpp在菜籽油中摩擦学性能的影响。结果表明： tbp和tpp能明显改善植物油的抗磨性并有效提高植物油承载能力；用神经网络建立的摩擦学模型能对目标样本进行有效预测，能节省成本；其它添加剂能影响tbp和tpp在菜籽油中摩擦学性能。
