firing precision meaning in English
射击精度
Examples
- From the view of modern weapon system fire precision demands , it is found out that the charge temperature measure maximum deviation should be less than 1 and the standard deviation less than 0 . 7 through reading firing table and making demonstration
而从现代火炮系统射击精度需求角度，经查阅射表和论证可知，药温测量的单向偏差应不大于1 ，标准误差应不大于0 . 7 。 - It can be used not only to change the fire precision of the base bleed projectile , but also to improve the effect of reduction drag and expansion range . the calculating model of the secondary expansive pressure of the burning gas is constructed by means of analysis of the experimental resuits , it has been confirmed that the new base bleed unit can be designed , with the secondary expansive principle of the burning gas pressure . the engineering project of a hybrid base - bleed - rocket high - level efficient extended - range projectile is designed , with the secondary expansive principle of the burning gas pressure , the feasibility and the true worth of its engineering applications is validated in theory
本文提出了底排燃气压力不随外部压力变化，既可改善底部弹射击精度又可提高减阻效果的二次扩张原理，建立了底排燃气二次扩张压力的计算模型，并通过采用二次扩张原理的新型底排装置与传统底排装置的对比试验，验证了新型底排装置结构实现的可行性；完成了基于底排燃气二次扩张高效增程原理的底排?火箭复合高效增程弹方案设计及其有关计算，从理论上验证了其工程应用的可行性和实际价值。
