The membrane structure and surface features were analyzed by ft - ir and scan electron micrography 用傅立叶红外光谱和扫描电镜分别测定了膜的结构和表面形貌。

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。
