In this paper, a new statistical viewpoint which represents the particle packing structure, particularly the radial distribution function, of powder bed was proposed and its validity was examined, numerically.<BR>1) This method is built up on the fundamental standpoint that the radial distribution function of randomly packed particle system can be regarded as a stationary wave of the particle density around a specified particle.<BR>2) By introducing the conception of particle density original wave function on the viewpoint of 1), it is described that the radial distribution function of randomly packed particle system is given by a stationary wave produced by the mutual interference between reflected wave from the specified particle and the particle density original function itself.<BR>3) The validity of this viewpoint was verified by using the results of the conventional calculation and also of computer aided simulation.
