The article analyzed the Franz Schubert's Piano Sonata, Op.120 all-around with the elements of multidimensional structures, such as the pitch, rhythm, and textures. It discussed the effect of change and ratio to the drive and structure of the music through the three aspects of combination: the synchronous change and symmetry ratio of the element rhythm, the asynchronies change and the asymmetry ratio of the element rhythm, and the synchronous with asynchronies changes, and compared them with the Heinrich Schenker system.

内容提要：本文以舒伯特《钢琴奏鸣曲OP.120》为例，对该部作品的音高、节奏、织体等多维音乐要素进行了综合分析，从要素节律的"同步变化"和要素节律间的"匀称比率"、要素节律的"异步变化"和要素节律间的"非匀称比率"以及要素节律的"同步变化"、"异步变化"的结合三方面，来探讨了这些"变化"、"比率"对音乐的动力、结构力的作用，并与申克的还原体系分析方法进行了比较。

On the other hand, we introduce the convergence theories for generalized alternating method, parallel synchronous iterative methods and parallel alternating synchronous iterative methods when the coefficient matrix are Hermitian positive definite matrices.

接着，讨论了当系数矩阵是Hermitian正定矩阵时广义交替迭代法，并行同步迭代法，并行交替同步迭代法的收敛理论。
