In this paper, the way of linearity superposition of controlled source as exeitation source is analysised, and the establishing of sparaity matrix is studied by example,furthermore computer network assistant anslysising is researched simply.

In this paper,we describe the state equation substitution—superposition method in linear circuit.

The performance of an ATM multiplexer is studied,the superposition of its multiply input ON-OFF sources is modeled by a poisson process with group arrivals.

A parallel iterative method for finding multiple zeros of a polynomial;

Discussion is given on the domain decomposition parallel iterative algorithm,which is aimed at the implicit difference equation under 3-D Cartesian coordination and the error estimates for both the serial and the parallel iteration are provided.
