【摘要】 <正> 多次标准加入法各测量点的Nernst方程为上式中,E^°=E^（°）+Slgγ_i。在以往的计算如三参数拟合法中,就把E^（°）当作常数来处理。这在E^（°）及γ_i变化很小的情况下是可行的。为此,必须规定严格的实验条件。如加入标液体积必须较小且浓度较大,添加次数不能太多,要加性能很好的离子强度稳定剂等等。否则三参数拟合法的计算结更多还原

【Abstract】 A method is described for correcting the effect of activity coefficient and liquid junction potential etc. on E in multiple standard addition method. It gives a new conception of linear perturbation constant and a new algorithm of four-parameter fitting. And a program is developed in which a set of data is computed on IMS-8000 microcomputer experimentally. The results are compared successfully with those of three-parameter fitting.更多还原
