Journal of Flow Control, Measurement & Visualization 2019年第2期7卷 111-119页

作者： Yusuke Hirose Kazuki Ishikawa Yoshiyuki Ishimoto Takumi Nagashima Masanori ota Shinsuke Udagawa Tatsuro Inage Kazuki Fujita Hideki Kiritani Koji Fujita Kiyonobu Ohtani Hiroki Nagai Graduate School of Engineering Chiba University Chiba Japan Aerospace Engineering Course Tokyo Metropolitan College of Industrial Technology Tokyo Japan Department of Mechanical Engineering Shonan Institute of Technology Fujisawa Kanagawa Japan Institute of Fluid Science Tohoku University Sendai Miyagi Japan

Three-dimensional density measurement of unsteady flow field around a sphere is carried out in the ballistic range at Institute of Fluid Science, Tohoku University. Simultaneous multi-angle measurement system using twelve digital cameras is installed in the test chamber of the ballistic range to achieve the three-dimensional density measurement. The Colored-Grid Background Oriented Schlieren (CGBOS) technique using colored-grid background is utilized for the reconstruction of density. The Mach number of the sphere is set to 1.5. The short pulse LEDs to illuminate the backgrounds are also installed in the chamber to capture the unsteady flow field around a flying sphere. Three-dimensional density distribution around a sphere is successfully reconstructed.

进行历史文献的音韵研究时,即使该文献中含有从前人小学书等文献中引用的注音,但一般都把它们看作是与作者所反映的语音系统一致的成分而接受,且仍可保证音韵特征的全面同质性。但反切这种标音方法对于不熟悉音韵学的人而言并不容易创造。因此亦有可能并没有经过深刻检讨,而从前人文献不改字面地直接引用其中的反切,最终做出语音性质上并不同质的著作,《玄应音义》就是其一例。编写早期佛经音义时未有所能依靠的前人佛教语言学书籍,因此只好利用现有的各种小学书以及其他各种文献里的注释、注音。玄应直接从反映江东音的原本《玉篇》中引用了大量反切,最终使他的《音义》虽然也含有反映他自己母语的西北方言(秦音)特点,但整体音系特征比《切韵》更接近于《玉篇》。

反映西北方音的《王三》反切

庚三(相配入聲爲陌)和清(相配入聲爲昔),雖然内部都不含有重紐對立,但是可以將兩者視爲一韻,形成一組對立的重紐韻,即前者(庚三—陌)B:後者(清—昔)A。在這一套B:A的重紐對立之中,幫B小韻的反切字面和歸屬在各版本的《切韻》系韻書之間... 详细信息

庚三(相配入聲爲陌)和清(相配入聲爲昔),雖然内部都不含有重紐對立,但是可以將兩者視爲一韻,形成一組對立的重紐韻,即前者(庚三—陌)B:後者(清—昔)A。在這一套B:A的重紐對立之中,幫B小韻的反切字面和歸屬在各版本的《切韻》系韻書之間有所差異。其中所謂《王三》作“碧:陂隔反”,屬於麥韻。麥韻只有二等韻類。而被切字“碧”爲三等韻字,當屬於庚三入陌韻或者清入昔韻。《王三》的這種處理方法可以理解爲在反映二等重韻庚二—耕的合併的同時,也反映了二等牙喉音聲母的顎化。如上介紹的例子並不是孤例。前一種現象(即梗攝二等重韻的合併)可見於同一時代的粟特—漢對音、藏漢對音以及日本的漢字音(尤其是所謂的“新漢音ShinKanon”)等材料之中;後一種現象(即二等牙喉音的顎化)則廣泛出現於同一時代的文獻材料《慧琳音義》之中。
