计算弹丸在炮膛内运动所需的极其缺少的数据是弹带材料对炮钢的摩擦系数。当弹丸定心部也在炮膛内滑动时,由于惯性作用和如同弹带情况一样不受尺寸妨碍,定心部的支承压
The extremely missing data required to calculate the projectile’s motion within the bore was the coefficient of friction of the lanyard material to the gun steel. When the projectile centering also slides within the bore, the bearing pressure of the centering part due to inertia and unimpeded size as in the case of the elastic band
