The membrane structure and surface features were analyzed by ft - ir and scan electron micrography 用傅立葉紅外光譜和掃描電鏡分別測定了膜的結(jié)構(gòu)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 本文以某船用鋼為研究對象,運用彈板侵徹試驗及顯微硬度、金相顯微鏡和sem等分析測試手段,研究了靶材在侵徹過程的物理變化和損傷規(guī)律,從而對尖頭彈和鈍頭彈侵徹船體鋼的物理過程有了較全面的了解。
