Using the method of discretization and numerical iteration, the precise visualization results of the distributions of electric field and charges are obtained by Matlab numerical simulation.

With the numeric calculating method applied to the reservoir flood routing operation,we introduced the numerical iteration,a new method which makes porgramme designing for flood routing operation easier.

By the equivalent Markov process, formulas of performance potentials and average-cost optimality equations for SMCPs are derived, and a policy iteration algorithm and a value iteration algorithm are proposed, which can lead to an optimal or suboptimal stationary policy in a finite number of iterations.

A fast value iteration algorithm, which leads to an ε optimal stationary policy, is proposed and the convergence of thi.

When the Jacobian matrix is rank-deficient or very ill-conditioned in numerical iterative process to solve the nonlinear least square problem,more methods with standard approaches such as the gauss-newton method or modified gauss-newton method will be in failure.

A numerical iteration method with one-dimension nonlinear mechanical modeling was (created) to analyze the transverse cracking of continuously reinforced concrete pavement subjected to (temperature) and drying shrinkage with consideration of the nonlinear bond slip between steel bar and (concrete) and the (nonlinear) friction slip between concrete slab and subgrade.

columns subjected to biaxially eccentric loading, a computer program of numerical iterative method for the strength analysis of inequiaxial L shaped cross section was specially compiled.
