It is a new therapeutic method enlightened by the theory of channels and collaterals and the theory of nerves, and advanced through clinical trials. It, therefore, exhibits not only the advantages of traditional acupuncture, but also its unique characteristics, yielding satisfactory results especially in pain of various origins. A report is presented below.展开更多

Based on related theories and methods,and using the wave velocity and density model of the crust in the Yanqing-Huailai Basin,this paper makes a simulation of ground motion at Guanting Reservoir Dam based on the scenario earthquake in the Yanqing-Huailai Basin. Comparative analysis shows that the results of 3D finite-difference simulation accord with those of the empirical formula. The parameters such as the velocity-time series of ground motion,PGV and frequency might be referred to for the analysis of seismic protection design of the dam's structure.展开更多
