With Liouville-Green transform, the asymptotic method to solve second homogeneous linearity equation was improved.

Reagarding the inertia force of rotor as the force acting on the shaft, the effect of thermal expansion upon the natural transversal vibration frequencies of rotor system is studied by a new nonlinear asymptotic method.

The dual asymptotic method developed previously by the authors is employed to solve the finite element equation.

? This paper mainly introduces the application of approaching method in the roadbed Construction by the explanation of the slope foot of the cutting slope.

This paper has sloved efficiently the calculating problem in axisymmetric body, which is made of incompressible hyperelasitic material and its nominal strain is average, by means of combination of asymptotic method and FEM.

For studying which one is more effective for the statistical power between the MonteCarlo Asymptotic Test and the Bootstrap Test, the power and scale of different nonlinear models are compared in this paper based on simulation, and the generalized linear test BDS, is also included.

Bounds of Ramsey Functions and Asymptotic Methods;

In this paper,an asymptotic method is presented for the analysis of a class ofstrongly nonlinear autonomous vibrating systems with many degrees of freedom.
