船体钢 meaning in English
hull steel
Examples
- 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。 - 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。
