迭代回归法计算T型电位滴定中试液含量

CALCULATING THE CONCENTRATION OF UNKNOWN IN POTENTIOMETER TITRATION OF T-TYPE BY ITERATIVE REGRESSION METHOD

本文将迭代回归法计算T型电位滴定中，叙述了其原理及数学推导，并运算了一批实验数据。结果表明，该法准确度较高，且不需空白溶液校正。

In this paper iterative regression method is applied to the potefitiometric titration of T-type, the principle and its mathe-matical deduction is described also. Using calculation program compiled by ourself a number of experimental data are calculated. The results obtainted show that this method has high accuracy and it need not be calibrated by using blank solution.
