A recurve bow coated in fibreglass has become standard , and arrows made of aluminium and carbon graphite can travel more than 240km h , but the most important requirements are straightforward : steady hands , strong shoulders , flexible muscles , sharp eyes and nerves of steel 覆蓋著玻璃纖維,向內凹進的弓已經成為了標準用具,用鋁和石墨制成的箭時速可高達240公里。然而,最關鍵的要求還是那么簡單:穩健的雙手強有力的肩膀柔韌的肌肉犀利的眼睛和鋼鐵一般的神經。

By the scattering factor of henke , we calculated the peak reflectence of all possible material pairs from the recurve method of thin film optics . from the calculating results , the best material pairs of the five wavelengths are determined 從薄膜光學理論的遞推法出發,以henke的散射因子為依據,計算了候選材料的峰值反射率,從中得到了軟x射線短波段的五個波長處的最佳材料配對。

Australian matt gray took aim at a yellow circle from 70m away no bigger than a thumbprint - and released an arrow from his recurve bow 澳大利亞的馬特?格雷瞄準一個黃圓圈(即黃心) ? ?在70米開外看上去只有個拇指印兒那么大? ?然后用他那反曲弓把箭射了出去。
