塔里木盆地三叠纪主要为内陆湖泊的陆相沉积。文中以沉积学理论为指导,以不同地区单井地层-沉积相柱状图解释为基础,对塔里木盆地三叠系进行了沉积相划分和沉积体系分析,并对沉积相类型、古地理环境及沉积相时空演化进行了系统分析。研究认为:早三叠世,塔里木盆地以湖泊和湖泊三角洲体系沉积为主,库车坳陷北部山前发育冲积扇-扇三角洲沉积体系;中三叠世,库车坳陷沉积格局变化不大,盆地内部湖泊面积有所扩大,塔北地区开始发育湖泊三角洲体系;晚三叠世,由于古特提斯洋持续向塔里木板块俯冲,特提斯南缘的羌塘地块与塔里木板块发生碰撞,受此构造运动影响,盆地内部湖盆开始向北退缩,塔北及库车坳陷开始出现含炭沼泽,盆地沉积演化开始向侏罗纪过渡。

为了改善现有脊柱康复训练设备的功能单一、结构复杂、训练模式不合理的现状。本研究通过对人体爬行运动进行建模,实现新型智能脊柱康复训练仪的设计。用Denavit-Hartenberg法对爬行训练仪进行运动学建模,得到其正逆运动学方程。使用MATLAB建模软件在预设康复轨迹下进行运动学仿真实验,对运动学求解进行验证。实验结果表明,脊柱康复训练仪能在预定轨迹下按爬行训练的要求运动,验证了脊柱康复训练仪结构设计的合理性。同时,由机械把手位置信息通过逆运动学方程计算得到的各关节的角度误差最大不大于3°,验证了所得运动学方程的有效性。

Acta Metallurgica Sinica(English Letters) 2014年第6期27卷 1083-1087页

作者： Xianglong Yang Kun Yang Yingxin Cui Yan Peng xiufang Chen Xuejian Xie Xiaobo hu State Key Laboratory of Crystal Materials Shandong University

The resistivities of vanadium-doped semi-insulating 4H-SiC wafers were measured by a contactless resistivity measurement system. Anomalous resistivity was found in semi-insulating 4H-SiC wafer. Raman spectra of semi-insulating4H-SiC wafer indicated that the anomalous resistivity was caused by polytype inclusion. Based on the activation energies of different SiC polytypes calculated from resistivity versus temperature data measured by COREMA-VT, the resistivities in the vanadium-doped semi-insulating 4H-SiC wafer with 6H polytype inclusion were calculated. The calculated resistivities are quite consistent with the measured resistivities. Furthermore, the compensation mechanism for the formation of anomalous resistivity was proposed.

Journal of Materials Science & Technology 2009年第1期25卷 115-118页

作者： xiufang Chen Liana Ning Yingmin Wang Juan Li Xiangang Xu Xiaobo hu Minhua Jiang State Key Laboratory of Crystal Materials Shandong University Jinan 250100 China

Thermal oxidation was used to remove the subsurface damage of silicon carbide （SIC） surfaces. The anisotropy of oxidation and the composition of oxide layers on Si and C faces were analyzed. Regular pits were observed on the surface after the removal of the oxide layers, which were detrimental to the growth of high quality epitaxial layers. The thickness and composition of the oxide layers were characterized by Rutherford backscattering spectrometry （RBS） and X-ray photoelectron spectroscopy （XPS）, respectively. Epitaxial growth was performed in a metal organic chemical vapor deposition （MOCVD） system. The substrate surface morphology after removing the oxide layer and gallium nitride （GaN） epilayer surface were observed by atomic force microscopy （AFM）. The results showed that the GaN epilayer grown on the oxidized substrates was superior to that on the unoxidized substrates.

关键词： SiC Thermal oxidation GaN epitaxy
