LUO Dao-bin; MIAO Run-cai; LIU xiang-lian; ZHU Feng

In order to study the damping characteristics of the liquid surface waves,the relation between the liquid surface wave amplitude and the spreading distance was testified experimentally and analyzed theoretically by means of laser diffraction.The experimental results indicated that the liquid surface wave amplitude declined exponentially with the spreading distance and the damping coefficient,which varied lineally with frequency,has dispersive characteristics.The conclusion is valuable for liquid surface wave detecting and application.
