In the paper following the change law of concentration and electric potential of different stage oxidation-reduction titration and appling the Nernst formula, it was discussed that the application of Ringbom error formula in symmetry donblet oxidation-reduction titration.

本文遵循氧化还原滴定各个阶段的浓度与电位变化规律，运用能斯特公式，探讨了能适用于氧化还原滴定中对称电对的林邦误差公式，具有便于记忆与应用等特点。

The fine-beam diffraction of ferroelastic twins has been studied in detailfor the first time,and we have demonstrated the spot splitting of the a-typeferroelastic twin of NdP5O14 in its Laue pattern.With the help of computersimulation,the twin symmetry and structures were determined from the char-acteristics of the spot splitting.
