      With the combination of the Krannov's function, a beam eigenfunction which satisfying clamp boundary condition is formed. It is found that the beam eigenfunction has a very high converging rate in isotropic beam. Satisfactory results can be obtained with only the first two terms in the series used in calculating the deformation of isotropic beam and the relative error can be controlled at about l percent. The beam eigenfunction is then used in laminated rect angular plate with all of its boundary clamping to calculate its deflection. A series of results which may be important in engineering are reached through the chdnge of referent data in laminated plate.
