The invention discloses a method for determining the maximum deflection of annular films of central zone rigid plates under uniformly distributed load. The method includes fixedly clamping the annular films of rigid plates by the aid of clamping devices with the inner radiuses alpha; forming an axial symmetry annular film of each central zone rigid plate; transversely applying the uniformly distributed load q to each axial symmetry annular film; determining the maximum deflection w of the annular films by the aid of measurement values of the uniformly distributed load q on the basis of static balance analysis of axial symmetry deformation problems. The thicknesses of the annular films are h, Young elastic modulus of the annular films is E, Poisson's ratios of the annular films are v, and the central zone radiuses of the annular films are b. The outer radiuses of the axial symmetry annular films are alpha, the inner radiuses of the axial symmetry annular films are beta, and the peripheral edges of the axial sy
