有些词语翻译过来怎么还是他本身啊
我是一句一句翻译的
对材料进行组织形貌分析的方法有:光学显微镜(OM)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、扫描隧道显微镜(STM)。材料的形貌是材料分析的重要组成部分,材料的很多物理化学性能是由其形貌特征所决定的。显微镜是由一个透镜或几个透镜的组合构成的一种光学仪器,是人类进入原子时代的标志。主要用于放大微小物体成为人的肉眼所能看到的仪器。显微镜分光学显微镜和电子显微镜:光学显微镜是在1590年由荷兰的詹森所首创。现在的光学显微镜可把物体放大1600倍,分辨的最小极限达波长的1/2,国内显微镜机械筒长度一般是160毫米。其中对显微镜研制,微生物学有巨大贡献的人为列文虎克,荷兰籍人。
SM一般指单模光纤。OM表示多模光纤等级,具体如下:1、OM1指850/1300nm满注入带宽在200/500MHz.km以上的50um或62.5um芯径多模光纤;
2、OM2指850/1300nm满注入带宽在500/500MHz.km以上的50um或62.5um芯径多模光纤;
3、OM3是850nm激光优化的50um芯径多模光纤,在采用850nm VCSEL的10Gb/s以太网中,光纤传输距离可以达到300m;
4、OM4是OM3多模光纤的升级版,光纤传输距离可以达到550m。
