1 概况 多年来在武器、弹药研制过程中,散布精度指标是使用方与研制方之间意见分歧最大、争论最多、最难确定的一个指标。一是使用方参照原制式武器,希望散布精度越小越好;二是研制方希望在质量大幅度减轻以后,散布精度指标适当放松,故而双方进行了较长时间的争论。本文以12.7mm机枪为例,以武器的射表值和试验值为依据,对武器的散布精度指标进 1 Overview Over the years, in the process of weapon and ammunition development, the index of spreading accuracy is an indicator of the most disagreement, the most controversial and the most difficult to determine between the user and the developer. First, the use of reference to the original type of weapon, hoping to spread the smaller the better; Second, the development side hopes to substantially reduce the quality of the spread of the appropriate index of relaxation, therefore the two sides had a longer period of controversy. In this paper, 12.7mm machine gun, for example, based on the value of the weapon's shot and test values, the accuracy of the distribution of weapons into the index
