【摘要】 本文介绍一种D-F-P拟牛顿最优化非线性规划用于多元混合酸线性滴定的直接求解;非线性模型是由Pehrsson等人于1976年发表的.本法的优点是收敛速度较快,迭代次数较少,适宜用于更多变量的非线性规划.计算求得三组分混合酸各组分的平均相对误差在3%左右,计算获得各组分酸的稳定常数与文献十分接近.更多还原

【Abstract】 Mixtures of three monoprotic acids can be determined by linear titration method ,the nonlinear model was presemled by lennart pehrss on in 1976 the D-F-P quasi -newton nonlinear optimization technique is introduced to solve the problem A computational program is written in FORTRAN and the calculation converges rapidly with fewer times of iteration the stability constants calculated are similar to those al ready published in literature and results of component contents are obtained with an average relative error of 3%更多还原
