Through watching movies, learners could better understand and appreciate the basic elements of a novel including plot, character, setting, narrative point of view, theme and style. Thus this approach is recommended to teachers and learners of British and American novels.展开更多

The mainresearch methods include laser-driven micro-impulse measurement experiment, surface triangulation three-dimension-al reconstruction calculation method based on laser-material interaction theory, simulation calculation based on orbitaldynamics, etc. It also looks forward to the future research direction in the field of this technology.展开更多
