目的　解决某加榴炮用全装药和 1 #装药量均需通过靶场测试来确定的问题 .方法　根据某加榴炮用全装药和 1 #装药量之间存在的一元线性关系 .结果　得出 1 #装药量和全装药量之间的一元线性回归方程 ,进行了相关系数分析和回归显著性检验 .结论　从理论上提出了一种 1 #装药量以计算代替靶场测试的方法 ,可用于指导试验 ,以减少试验量 Aim To solve the problem that a certain loaded gun with full charge and 1 # charge must pass the shooting range test.Methods According to the unilinear linear relationship between the full charge of a certain loaded gun and the charge of 1 #. Results The linear regression equation between 1 # charge and full charge was obtained, and the correlation coefficient analysis and regression significance test were carried out.Conclusion A 1 # charge was proposed to replace the shooting range test The method can be used to guide the test to reduce the amount of test
