摘　　要：One of the forward situations in the study of water waves is the basic three-dimensional surface wave motion of short-crested waves.Capillary waves result in rich effects concerned closely with remote sensing in the open ocean.Ocean currents experience a complete process in surface wave motion.Based on the above ideas,a linear dynamical system of surface capillary-gravity short-crested waves is developed by considering the current effects,thus leading to the following analytical expressions of the kinematic and dynamic variables:the wave height,the wave steepness,the phase velocity,the wave-particle velocities,accelerations and trajectories and the wave pressure.A number of the classi-cal,typical and latest special wave cases can arise from these expressions.One of the forward situations in the study of water waves is the basic three-dimensional surface wave motion of short-crested waves.
