| 摘要: | 本研究目的在探討不同箭頭重量在不同距離發射對於箭著分佈之精度的影響。研究方法透過一套自行設計的機械手臂，將弓箭固定在相向條件的環境下，分別在不向比賽距離發射各種箭頭重量的箭，之後將方格紙上的箭著位置座標(X, Y)記錄，並且計算其精度，再以SAS 8.2級統計分析軟體進行二因子變異數分析(two-way ANOVA)。經過對結果的分析與討論後，得到下列結論：一、較重之箭頭重量有助於提升90公尺箭中靶的精度。二、男子全項比賽中可選擇在各距離箭著精度較穩定的100gr、110gr、120gr箭頭。三、發射距離愈遠，不同重量的箭頭皆會得到較差的精度。
The purpose of this study was to investigate the effect of different weights of arrow points, shot from different distances, on the precision of the distribution of shooting locations. A custom-made mechanical arm was used, and various weights of points were shot from different distances. The arrow impact position was recorded on the Graph paper by X-Y site coordinates, and calculated the precision of the distribution of shooting locations. The data was analyzed by two-way ANOVA. The author concluded: A. Heavier point is helpful for the precision of 90 meters. B. Male can choose such as: 100-grains, 110-grains, 120-grains point in the competition for its steady precision. C. With different weights of arrow points, the farther the distance is, the worse precision will get. |
