A new method to study the structure of solution with the D/MAX 3B θ～2θ type powder diffractometer by refrection has been described in the paper. Taking the diffraction measurement of Li 2SO 4 solutin as a sample, some tactics of data collection have been discussed from a few aspects,such as alignment of goniometer, option of slits and wavelength,determination of step angle and fixed time. Experimental results of the diffraction measurement have been given.
