In this paper, we report the study of adsorption and dissociation of oxygen on a polycrystalline Ag surface by means of optical second-harmonic generation ( SHG ) in a Ultra-high vacuum. 本文报道了在超高真空(UHV)环境下用光学二次谐波方法研究氧在多晶银表面的解离过程。
CCD electric ultra-high vacuum gate valve uses electric device to drive the stem, moving valve disc updown to make the valve opened or closed. CCD型电动超高真空(UHV)插板阀是通过电动装置驱动阀杆带动阀板作上下运动,达到阀门的开启或关闭。
CC manual ultra-high vacuum gate valve uses a handle to drive valve disc up and down to perform open and close action. CC超高真空(UHV)插板阀是以手柄带动阀板作上下运动使阀板开启或关闭。阀门用于接通或切断真空管路中的气流。
This experiment using the ultra-high vacuum low temperature scanning tunneling microscope to measure the self-assembled structures of rubrene on the surface of Pb island and the magnetic nanometer lattice of Co on the surface of Bi ( 111 ). 本实验利用了超高真空(UHV)低温扫描隧道显微镜,测量了红荧烯在铅岛表面的自组装结构和Co在Bi表面的磁性纳米点阵。
