Extended quantum confinement luminescence center model for photoluminescence from oxidized porous silicon and nanometer-Si-particle- or nanometer-Ge-particle-embedded silicon oxide films

Materials Research Bulletin

Through analysis of the latest experimental results reported in the literature and obtained in our laboratory, we have extended our previous quantum confinement/luminescence center model for the photoluminescence mechanism of porous Si and of nanometer-silicon-particle-embedded Si oxide films (G.G. ...

腐蚀学报（英文）

用金相显微镜、扫描电镜、X射线衍射仪和X射线能谱仪对天然气井油管悬挂器腐蚀失效进行了检测分析，并对天然气井油管悬挂器用35CrMo钢进行了盐雾试验，结果表明，天然气中的水和CO2是引起腐蚀的主要介质，腐蚀产物主要是FeCO3，高速天然气冲刷和钢中的非金属夹杂加剧了腐蚀的速度. CORROSION FAILURE ANALYSIS OF AN OIL TUBE USED IN NATURAL GAS WELL LIU Shou-ping,ZHOU Shang-qi,WANG Jia-mei,REN Qin Chongqi...
