This method was called Ion Assisted Reactive Evaporation (IARE). The modified SiC coating was prepared using CH4 and Si with Kaufman ion source by IARE at 300C and it had met the requirements of applications. The SiC coating prepared by this method was amorphous. It was dense  homogeneous and easy to be polished. The surface modification of a SiC mirror was carried out using SiC coating by this method and achieved a fine surface modification effect. The surface roughness (rms) of the SiC substrate was reduced to 0.862nm  the scattering coefficient was reduced to 2.79% and the reflectance coated with Ag film was improved simultaneously after the surface modification. The effect of surface modification using SiC coating was close to that of using Si coating. It can be drawn that this technological method to preparation SiC coating for the surface modification of SiC mirror is reasonable and effective. 2011 SPIE.   The influence of temperature on the diffusion of I-125(-) in Beishan Granite 期刊论文  OAI收割 RADIOCHIMICA ACTA, 2010, 卷号: 98, 期号: 5, 页码: 301-305 作者:  Chen, T.;  Sun, M.;  Li, C.;  Tian, W.;  Liu, X.   |  收藏  |  浏览/下载：7/0  |  提交时间：2019/04/09 Temperature Effect  Effective Diffusion Coefficient  I-125  Beishan Granite  Hlw Disposal   Effective temperature calculation and Monte Carlo simulation of temperature effect on Muon flux 期刊论文  OAI收割 HIGH ENERGY PHYSICS AND NUCLEAR PHYSICS-CHINESE EDITION, 2004, 卷号: 28, 期号: 2, 页码: #REF! 作者:  Meng XW(孟祥伟);  Meng, XW 收藏  |  浏览/下载：15/0  |  提交时间：2016/04/12 temperature effect  effective temperature temperature coefficient  muon flux
