for identical plane of sample and glass plate.
When we fill up a sample at a holder, if a surface of sample is identical with a surface of holder, A rotation-axis of goniometer is identical with a surface of sample(Fig. 12(a)). If a surface of sample is higher or lower than a surface of holder, a diffraction line is shift to one side(Fig. 12(b)), thus we undergo a difficult analysis.
