查询词典 variance ratio

Through similar simulation test of block top-coal drawing, the influence of coal block size and block position in top coal on the recovery ratio and drawing manner is studied. It is found that the drawing manner has the different adaptation to the top coal which has different block distribution. The caving capacity is mainly decided by the block size. The top-coal which has layer difference of block with the same size has different recovery ratio. It is shown, that, to the given top-coal blocks, the recovery ratio of uniformly mixed blocks is maximal in the manner of drawing at interval of one support.

研究表明，顶煤块体大小是影响顶煤回收效果的主要因素，在顶煤块径一定的条件下，块体层位分布不同是造成顶煤回收率差异的主要原因，研究表明各级块度均匀混合时顶煤回收效果最好，块度从下向上增大分布次之，大块为中位顶煤时回收效果最差；各种放煤方式的适应性不同，各级块度均匀混合的顶煤适合用间隔放煤；块度从下向上增大适合用顺序放煤；大块在顶煤中位分布时，中硬煤以下适合用间隔放煤，硬煤应采用顺序放煤方式。

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。
