The three distinct characteristics including use case driving,center of architecture,the procedure of increment and iterations,is also detai.

And an incremental iterative algorit.

Considering the influence of edge effect,the static-electricity driven torque was amended,the nonlinear mechanical model of a torsion micromirror was established and the static mechanical equation of micromirror was solved by an incremental iterative algorithm.

In order to guarantee the convergence and stability in solving nonlinear algebraic equations, an incremental iterative algorithm was put forward according to the load characteristic.

Image restoration based on least-squares increment iterative and regularization method;

Based on the analysis of the relation between use case and software architecture, the author presents a method of iterative increment driving by use case for constructing software architecture and its model; and analyses the process of incremental iteration and relevant issues.

We research a new software development methodOO iterative incremental development method banded with fast prototype method and object-oriented technology and apply the method to the projects development on post internet bank system.

It puts forward a new software development method-OO,iterative incremental development method banded together fast prototype method and object-oriented technology.
