尖头弹的英文
spitzer
例句与用法
- Targets made of ship - building steel , which is concerned , were penetrated by conical and flat - ended projectiles . the damage and failure behaviors of targets have been studied systematically by micro - hardness , metallography and scanning electron micrography . the results show that the ductile hole failures and back - surface petal failures are achieved when targets penetrated by the conical projectiles
本文以某船用钢为研究对象，运用弹板侵彻试验及显微硬度、金相显微镜和sem等分析测试手段，研究了靶材在侵彻过程的物理变化和损伤规律，从而对尖头弹和钝头弹侵彻船体钢的物理过程有了较全面的了解。 - Ballistic limit ( m / s ) vi - i vl - 2 vim vli - 2 325 399 535 902 based on the analysis of failure model of ductile target penetrated by conical projectile , a new energy function is obtained , as follows , ? 88 . 4547 the ballistic limit can be predicted using the function and satisfactorily accords with the actual results
在分析已有模型的基础上，建立了一个新的尖头弹侵彻延性材料时，靶材的塑性功表达式，即哈尔滨工程大学硕士学位论文利用上式计算尖头弹侵彻时的弹道极限，结果吻合较好。 - According to the land forces criteria ( u . s ) for ballistic limit and by using the method that the ballistic limit is equal to the average of two velocities that are partly penetration velocity and completely penetration velocity respectively , the ballistic limit is determined targets penetrated by both conical and flat - ended projectile , the result can be in the table
结果表明，不论是尖头弹侵彻还是钝头弹侵彻，这两个板厚的船体钢的弹道极限均未超过常规弹速范围，一般的枪炮可轻易达到这一范围，因此从这个意义上说，这两个板厚的船体钢的抗侵能力不是很理想。
