The scope of particularity of Mongolian bow instrument "Choir" is very broad.

蒙古族弓弦樂器"潮爾"的特殊性問題,涉及的范圍非常廣泛。

The conception,characteristics and kinetic behavior of the prestressed sector-bowstring structure were described.

闡述扇形弓弦預應力組合結構的概念,介紹該結構的特點和受力機理;運用有限元軟件ANSYS對弓弦結構進行靜力計算,分析矢跨比、垂跨比、弓梁截面慣性矩和腹桿數目對扇形弓弦預應力組合結構受力性能和變形的影響,得出了這些參數對扇形弓弦預應力組合結構的影響關系。
