The authors discussed the positional method in mathematics and its function on Chinese ancient siyuanshu, The arrange in positional order of siyuan rod_arithmetic model lays a foundation on the mechanization of its soluble procedure, and Zhushijie s siyuan solution suits the needs of the Chinese mathematical mechanization, which is of great value to the realization of mathematical mechanization.

By means of the analysis of crystalline structure and verification of experimental data, a hypothesis is proposed: under the action of applied magneic fields, the directional ordering of the atomic pairs will produce a induced magnetic anisotropy and disappear the structure of crystals.
