| 摘 要： | The Reissner equations of elastic plates are rederived on the bases of the incomplete generalizedvariational principle of Complementary energy.The Stress function to is naturally obtained from thevariational Calculation in the form of Lagrange multiplier.The stucture of solutions of the Reissnerequations is thus defined.On the bases of these discussions,a simplified theory has been put forward,in which the equations of equilibrium involving the shearing influence can be reduced into a fourthorder differential equation similar to those of the Classical theory of plates.
