A novel method was introduced for measuring a whole 3d surface shape of an object with a structure light emitter, a single CCD camera and double-orientation technology.
本文介绍了利用光截面发射器、单ccd摄像机和双定向技术实现物体表面三维自动测量的系统。

Surface morphology and composition analysis of the failure emitter of hollow cathode were characterized by using FESEM and EDS.
利用场发射扫描电镜(FESEM)及其附带能谱仪研究了失效空心阴极发射体的表面形貌、元素组成。

In contrast, if the emitter ledge is too thin, it may not effectively passivate the surface.
