| 摘 要： | 探讨重力、科里奥利力和不同等级风速对小口径步枪、男子速射、女子慢加速3种射击项目中子弹轨迹偏转的影响程度。应用力学原理,通过数理分析,结合射击项目对影响因素进行评价。提出:重力是影响射击比赛中子弹轨迹偏转的最重要因素,重力引起子弹轨迹竖直方向的偏转影响了比赛的成绩;小口径步枪的成绩受科里奥利力的影响显著,且随纬度的增加影响程度变大;风速大于4级时,将影响小口径步枪项目的成绩,随风速的增加影响程度变大,风速较小时,可以不考虑这方面的因素;男子速射、女子慢加速项目的成绩几乎不受科里奥利力和风速的影响。

| Abstract: | How bullet trajectory deflection shooting during three projects of small-calibre rifles, male rapid fire and the female slowly accelerate affected by gravity, Coriolis force and different levels of wind speed were explored. Mechanics principles and mathematical physics analysis were applied, and factors which affected flight trajectory during three projects were evaluated. Some conclusions were addressed. Gravity was the most important factor effecting on trajectory of deflection shooting competitions, and competition results were caused seriously by gravity, which affected bullet trajectories vertical direction deflection. Competition results of small-calibre rifles were affected by Coriolis force significantly, and the higher degree of latitude the more affected. The results of small-calibre rifles would be affected if wind speed greater than 4-level, and the bigger of wind speed the more affected. These factors were not considered if wind speed smaller. Men rapid fire and the woman slowly accelerate projects were not affected by wind speed and Coriolis force. |
