The spectral element method (SEM) on variable-resolution grids: evaluating grid sensitivity and resolution-aware numerical viscosity
spectral element method variable-resolution grids
2014/12/19
We evaluate the performance of the Community Atmosphere Model's (CAM) spectral element method on variable-resolution grids using the shallow-water equations in spherical geometry. We configure the met...

扫描电镜—阴极发光 石英 微结构 岩石成因
2012/7/25
综述了国外扫描电镜—阴极发光（SEM-CL）成像技术在岩石学研究中的应用实例。采用阴极发光探测器和扫描电镜结合的方法对石英等矿物进行观察，可以在高放大倍数和高分辨率下获得其他方法所无法揭示的丰富的微结构信息，如暗条痕和斑块、愈合裂纹、环带、复杂剪切纹、面状结构等，这些不同的微结构成为不同类型岩石中所特有的特征，因此，对沉积岩物源示踪具有较重要的参考价值。岩浆岩及热液石英中所显示的穿插结构、溶解结构...
