In this paper the isotropicalized outside singular point method for solving the bending problem of reienforced concrete plate is proposed.

In the present paper, tin- problem of Keissner s plate is transformed into a series problems of Kirchhoff s plate by perturbation, and then the simple Green s function of Kirchhoff s plate is used tor the outside singular point method.

On the Existence and Uniqueness of Limit Cycles for Lienard-Type Eqations with Multiple Singular Points;

Aiming at the problem of the odd point in the calculation of rotors torsional vibration characteristics by using the improved Riccati method, this paper presents a new viewpoint about how to confirm and remove the lost root and the added root of equation.

The odd point of plane differential systems =-y+δx+axy+my 2+ly 2n+1 , =G(x), is studied.

Application of Creen formula with singularity in the boundary of integral domain;

To resolve this problem that the original methods can′t efficiently distinguish MECG interference from EHG signal,this paper applies the method based on the singularity check of wavelet transform and the signal reconstruction of modulus maxima to remove the MECG interference in EHG signal, by using wave characteristics of MECG interference.
