The arquebus is a very heavy weapon compared with the bow , and tires out soldiers on the march ; their aims grow unsteady after half an hour ' s rapid firing 火绳枪是很笨重的武器，使士兵在行军途中很容易疲劳，而且他们的射击精度很不稳定，纵使只经过了半个小时。
Panzer elite panzer iv infantry support tank had its main weapon accuracy increased vs tp _ infantry ( us and wehrmacht infantry ) and tp _ infantry _ elite ( us rangers ) from . 4 to . 5 装甲精英四型步兵支援坦克主炮对英军步兵以及美国游骑兵射击精度倍数由40 %增加到50 % 。
A method to calculated influence of meteorological elements me asurement errors on firing accuracy is discussed ; the effect of meteorological measurement errors on firing accuracy is analyzed 讨论了气象条件测量误差对射击精度影响的计算方法，分析了其对射击精度的影响。
Our country ' s cruise missile enterprise had a big disparity with the international advanced level , especially the missile ’ s firing accuracy , although had having the big development 我国巡航导弹事业虽已有了较大的发展,但与国际先进水平相比差距仍较大,尤其是导弹的射击精度仍处于较低的水平。
On the basis of existing theory technology , in order to raise the marksmanship accuracy and injure probability in the fire control system , the control algorithms which improve marksmanship accuracy are set up 在现有理论技术的基础上，为了提高火炮系统中的射击精度和毁伤概率，建立了提高射击精度的控制算法。
In order to improve precision of the howitzer and look for the optimal overall parameter , dynamic optimization of howitzer was carried through by combining adams software and niche genetic algorithm 摘要为提高火炮射击精度，寻找最佳的总体参数，本文利用小生境遗传算法，实现了与adams软件联合进行火炮总体参数动力学优化设计。
In fire control systems , it plays an important role in shoot precision whether the distance of the targets is precise or not . modern fire control systems usually use laser rangefmders to measure the distance of targets 在火控系统中，目标距离测量的准确与否对火控系统的射击精度起着非常重要的作用，现代火控系统一般采用激光测距机测量目标的距离。
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 。
The forth , from the result of regression analysis , the firing accuracy of projectile effected by random factors is studied , and the suggestion that the test of projectile ' s firing accuracy can be replaced by measuring some parameters is put forward 第四，由回归分析结果，分析了随机因素对弹丸射击精度的影响，并提出弹丸的射击精度试验可由某些参数的测量来代替的设想。
Vibration of tank gun in the process of firing is one of the main factors that affect its firing accuracy , especially the instantaneous angular motion and the instantaneous linear velocity at the point of gun muzzle when the projectile leaves the barrel bore 影响坦克炮射击精度的主要因素之一是火炮振动，起关键作用的振动分量是在弹丸出炮口瞬间炮口振动角位移和横向线速度。
