原文对影响自由挑流射程的主要因素及射程(水舌內线)的估算方法作了很多研究,除建立了經驗計算公式外,还正确地指出鼻坎反弧半径R与单寬流量q对射程L值有极密切的关系。笔者认为,原文对影响自由挑流射程主要因素分析中,有些問題尚待进一步商榷。 (一)自由挑流射程理論式最优挑角α_a的确定原文认为,当α=30°～40°,其他条件一定时,射
The original article has made a lot of studies on the main factors influencing the free-range shooting range and the estimation of range (the waterline inside). In addition to establishing the empirical formula, it also correctly points out that the radius R and the single-wide flow rate q Range L value has a very close relationship. The author believes that the original text on the impact of freedom of the main factors in the pick-up range, some issues to be further discussed. (A) free-range range theory optimal angle α_a determine the original text that, when α = 30 ° ~ 40 °, the other conditions are certain, shoot
