By the analysis of wave mechanics of typical percussive drilling system of rock, characteristic parameter a, which describes wave dynamics and structure of the percussive drill system, has been presented.

By using wave mechanics, the process of impact driving pile is analyzed,and a mechanics mode of impact driving system which consists of hammer spring cup and pile is established.

After studying Schredinger equation,we find that relativity is the inner natural property of wave mechanics.

Study on Emulsion Polymer Hydrodynamics and Injection Technology

"Modern and ancient tidal sedimentation and sedimentary sequences","tidal hydrodynamics-sediment dynamics and morphodynamics","impacts of global change and human activities on tidal environments" and "physical and mathematical modeling techniques for tidal environments" were considered as the focus topics.
