A GRAPHIC DETERMINATION OF THE DRIFT CONSTANTS IN DEBYE SCHERRER PHOTOGRAPHS AND THE ACCURATE EVALUATION OF LATTICE CONSTANTS
德拜-谢乐照相中测定流移常数的图解法与点阵间隔的准确测定

The present paper describes a graphic method of determining the drift constants in Debye-Scherrer photographs and discusses the various methods in the evaluation of lattice constants. By the method proposed by the author, the accuracy of lattice spacings determined reaches 1 part in 500,000.
