Precision of meshfree methods and application to forward modeling of two-dimensional electromagnetic sources被引量:2
《Applied Geophysics》2015年第4期503-515,627,共14页李俊杰 严家斌 皇祥宇

Two-dimensional frequency-domain acoustic fullwaveform inversion with rugged topography被引量:1
《Applied Geophysics》2015年第3期378-388,467,468,共13页张钱江 戴世坤 陈龙伟 李昆 赵东东 黄兴兴 
financially supported by the National High Technology Research and Development Program of China(No.2012AA09A20105);the National Science Foundation Network(No.41574127)
We studied finite-element-method-based two-dimensional frequency-domain acoustic FWI under rugged topography conditions. The exponential attenuation boundary condition suitable for rugged topography is proposed to sol...
