音响学

Centralized by discussing the sonic showing manner of music work, the article uses the experience from ethnomusicology applying it to face the real sound directly, and taking Mozart抯 Piano Sonata K330 as an example to do a thorough comparison between the sonic showing manners of Vladimir Horowits, Glenn Gould, Claudio Arrau, Ingrid Haebler and Andras Schiff according to their performance recordings.

本文以音乐作品的音响呈现方式为论述中心，借鉴民族音乐学直接面对具体音乐事象的研究方法，直接面对实际发声的音响，以莫扎特第十首钢琴奏鸣曲（K330）为个案，通过霍洛维兹、古尔德、阿劳、黑布勒、希夫的演奏录音对他们的音响呈现方式进行全方位的比较。

The reason why that piano has the good name "king of the musical instrument" is not only because it has the wide sound areas, grandiose volume and the free inflexion. The most important is that it has various sound of harmonic with multi-tune and very abundant implication related to "temperament", which is also a symbolistic sign of the current tuning system.

钢琴之所以有&乐器之王&的美称，除了它有广阔的音区、宏大的音量、自由转调等因素之外，更重要的是它还具有变化无穷的和声复调音响以及与此相关的极其丰富的&律学&蕴涵，钢琴是当代律制的一种象征标示。

"Research on Temperament of Piano Sound" is a systematic description related with aesthetics about mathematics and physics of temperament study of piano art sound in the deep layer, opening out comprehensively the abundant implication of the swing on piano. Piano is not the musical instrument with only twelve-tone-equal temperament, and its structure of sound has three tuning systems in which twelve-tune-equal temperament is as basic frame, and just intonation and circle-of-fifths system are as addition.

&钢琴音响的乐律学研究&是对钢琴艺术音响进行深层系统的数理审美之描述，全面揭示钢琴丰富的音律蕴涵，即钢琴并非是单一的十二平均律乐器，其音响纵横结构是以十二平均律为基本框架，兼有纯律、五度相生律在内的&三律&乐器。

Objective: To study the effect of polycythemia on blood oxygen saturation.

裴蕾目的：观察RBC剧增而引起的高粘血症对血氧饱和度的影响。

Based on SIMPLER algorithm in the curvilinear body-fitted coordinates, the calculations were performed for Pr=0.7, Re=10~1000 on non-orthogonal non-staggered grids which are generated by elliptic equation systems.

采用曲线坐标系下压力与速度耦合的SIMPLER算法，数值研究了周期性渐扩渐缩波纹通道内脉动流动与换热情况，流动Re数的范围为10~1000，Pr数为0.7。
