摘要
地面火炮毁伤目标所需的弹药消耗量是一随机变量。在研究该随机变量的概率特征时 ,过去的文献通常假设地面火炮的携弹量为无限或为某一固定常数。该文研究用广义离散型随机变量的概率分布表征火炮携弹量的各种可能情况 ,较为完美地统一出一个共同的表示形式 ,并导出了计算毁伤目标所需弹药的平均消耗量的公式 。
The ammunition consumption for a ground cannon to kill a target is a r andom variable. In researching the probability characteristics of the random variable, all the articles in the past usually supposed that the ammunition sup ply of the ground cannon was unlimited or a constant. This paper reveals all pos sible situations of the ammunition supply of a cannon by the gener discret e random variable and gives a common expression for all the situations. The form ula to calculate the mean ammunition consumption for a cannon to kill a target is deduced. Finally,a practice example for analyz ing the mean ammunition supply for killing a target is given.
