地震弹性波正演，边界条件是最优的cpml，包括各向异性，粘弹等，很有用(Seismic elastic wave forward, the boundary conditions are optimal cpml, including anisotropy, viscoelasticity, etc., useful)

没有用，随便上传的，一会说必然会把握科技和室内的(An all-DC offshore wind farm with series-connected turbines)

说明：  本书是美国电力研究院（EPRI）组织“电力系统工程丛书”中，一部专门阐述电力稳定与控制的专著。随着世界范围内电力系统互联逐步扩大、新技术的不断采用、经济性以及电力工业调整所带来的约束，现代电力系统正日趋复杂。因这部专著的帮助，读者可以有效地解决由于电力工业的巨大变化所带来的稳定与控制方面的问题。(This book is a monograph on power stability and control in "Power System Engineering Series" organized by EPRI. With the gradual expansion of power system interconnection in the world, the continuous adoption of new technologies, economy and the constraints brought by the adjustment of power industry, modern power system is becoming increasingly complex. With the help of this monograph, readers can effectively solve the problems of stability and control brought about by the great changes in the power industry.)

this is the grid connected fuelcell which has chopper and also inverter modelled and descriptiop file also.
