Abstract Three methods for the use of "single grain" oscillating crystal identification when the spots on the film were lacking or "residue" have been suggested, It makes the identification for superfine grains more exact and more accurate by finding out the matrix equation about the orientations in space and indices of crystallographic planes; by measuring the angles between the planes that can be represented by the spots on the film; and by taking down the number of the spots which belong to the same d value, in order to find out whether the "single grain" consists of a few crystals or of a multiphase substance. Attempts have also been made to revealing the presence of α-SiO_2 by these methods as well as to further verifying the proposed formulae and figures.
