Some combinations of simultaneous equations for obtaining lattice constants of low-symmetry crystal systems can lead to a serious accumulation of errors and the formation of abnormal state equations. A method of solving the nermal state equations to obtain lattice constants by using the inverse matrix to discriminate the stability of simultaneous equations is given in this paper. Pratical example proves that the method is quite explicit and reliable and satisfactory results can be obtained.
