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。
This dissertation focuses on firing accuracy of projectile effected by random factors . the main contents are included as follow : the first , a model of launching dynamics of projectile is set up , and the numerical calculation software is programmed 本文围绕随机因素对弹丸射击精度影响展开研究，主要包括四个方面的内容：第一，建立了较为完善弹丸发射动力学模型，并编制了相应的计算分析软件。
It is hoping us can grasp each kind of influence reason that affect cannon firing accuracy how size influence and how essential probability in actual firing . it is hoping be help to effectively improve cannon firing accuracy and first - round - hit probability 希望在实际射击时就身管弯曲这个问题，能全面把握各种影响因素对射击精度影响大小及对其进行修正的必要性，有效的提高火炮射击精度和首发命中概率。
With the improvement of firing rate and firing accuracy of the medium caliber naval gun system , and the development of ammunition technology , especially the application of high - tech fuse , this provide an effective approach to enhance anti - missile efficiency of the medium caliber naval gun system 摘要随着中口径舰炮发射率和系统射击精度的提高，以及弹药技术的发展，尤其是高技术引信的应用为提高中口径舰炮武器系统的反导效能提供了一条有效技术途径。
Although the fire of shipping guns has been a hot - spot in the field of research . experimented much , written about much , the results with authority and feasibility has been few . this volume discusses its characteristics and essentials in depth and detail s , creates a new method of fire , and probes deeply into the influence of ship movement on fire and firing accuracy , which enriches gun fire 船载炮射击早已成研究热点，试验颇多，论文颇多。但权威性、可行性成果极少见。本文深入而具体地论述了船载炮射击的特点、要领，创新了其射击方法，并针对船体运动对射击精度的影响，进行了深层次的理论研究，丰富了船(舰)载炮射击的理论成果。
Having combined external ballistics with gunnery and proceeded from the practical needs of the field artillery , the influence to the firing accuracy by artillery metro report and the improved measures have been studied and analyzed in this essay , thus having obtained a series of valuable and pragmatic conclusions which mean a lot in practical application 论文结合外弹道学理论和炮兵射击学理论，从地面炮兵的实际需要出发，具体研究了地面炮兵气象通报对射击精度的影响及改进措施，提出了建立我军地面炮兵专用层权及通用层权的方法及改进计算机通报的措施，得出了一系列具有一定实用价值与相当指导意义的结论。
This thesis present the systematic studies on firing accuracy and firing accuracy tactical & technical requirement reasoning for gunnery system . the main contents of the paper are as follows . ( 1 ) definitions and probability distribution expressions for error of fire , error of firing data and error of dispersion are given summarily . methods to compose error of initial firing data and error of dispersion are discussed 本文对远程炮武器系统射击精度及射击精度战术技术指标论证等方面问题进行了深入、系统的分析研究，本文研究工作的主要内容有： ( 1 )概要地讨论了射击误差、诸元误差、散布误差的定义及其概率分布，诸元误差、散布误差及射击误差的合成，分析了射击精度的各种表示法，阐述了火炮武器系统准确度、密集度和首发命中概率的估算方法。
Aimed at tube curve by sun shining , it analyzes and calculates the instance of curve when tube up and down face have difference in temperature , and discourses upon it influenced degree to cannon firing accuracy . for hot spread asymmetry caused tube curve , it explains it ' s form cause . for irregularly hot stress acting tube curve , it stressfully analyzes effect of body tube wall thickness difference 重点分析了身管热弯曲产生机理，针对太阳照射下的身管弯曲，分析计算了身管上下表面存在温度差时的弯曲情况，论述了其对火炮射击精度的影响程度；对于散热不均引起的身管弯曲说明了其形成原因；对于不规则热应力作用下的身管弯曲重点分析了身管壁厚差的作用。
