Second-order hyperbolic equation difference schemes with two parameters;

Considering the inconsistence of user s knowledge of traffic information in real life,this paper studies the assignment problems of stochastic user equilibrium under two parameters and presents an equivalent mathematic planning model,which proves the equivalence and uniqueness of the resolution to the model,designs a correspondent resolution algorithm and carries out computation by the algorithm.

In this paper,using coimbinatorial theory,we find a new chain of the Jensen inequalities with two parameters,it is an extension of Jensen inequality with one parameter.

In this paper, we extend the concept of quantum Lie algebra to two-parameter case.

Finite difference method on double parameter elastic foundation board;

Finite difference method for the analysis of double parameter elastic foundation beam and the foundation beam s features in deformation and contact pressure;

In view of the shortage of the Winkler foundation model,the double parameter foundation model which consider shear force is presented,an equilibrium differential equation is developed according to this model,internal force and displacement calculation of finite difference solution is obtained,and a relative computer program has been work out.

A new approach of full-mode flutter analysis with double parameters is proposed,which is realized in ANSYS,based on the full-order discretized physical model of structure.

The supporting and restraint condition of dowel steel in rigid pavement joint could be simulated more truly with double-parameter foundation model than with single-paramet.

The double-parameter foundation model is used to improve the Winkler model,and the finite difference method is adopted to resolve the differential equation of the beam on elastic foundation under any linear load and linear equations that can be easily used in practical engineering are obtained.

The calculation of displacements and internal forces of the cantilever-retaining pile for foundation pit using biparameter method of foundation resistance is discussed.

This paper confirmed that foundation coefficient by means of biparameter method and the analytical .

In this paper,in terms of the measured data(including the deflection and slope at the ground surface of the pile,the maximum bending moment and its position),the biparameter method is used to analyze the pile-soil parameters.
