A new fault location function was generated based on the matching idea of selecting a reference point to match the fault position.

Based on five states that would arise in the matching of labor and capital in economy,the paper analyzes the ideal matching term of capital and labor under the condition of manufacturers in the environment of competition and then analyzes influence on collocation of investment factors that would come into being because of the gap of real and ideal matching of capital and labor in economy.

This thesis chooses from the aspect of the distribution ideology, with the harmonious socialist society theory as guide, take the right management of the fairness and efficiency relation as study fulcrum, With the leading distribution ideology after the establishment to our coun.

This paper presents a new scheme,which is used in discretizing Berenger s split field representation of Maxwell s equations,in order to use the perfectly matched layer(PML) with the alternating direction implicit(ADI) finite-difference time-domain(FDTD) method instead of the standard FDTD method.

Absorbing performance of one-dimensional perfectly matched layers (PML) isanalyzed and its theoretical reflection coefficientis presented in consideration of the influence of thefinite-difference approximation in this paper.

The interior region,treated using the FEM,is truncated to a single periodic unit cell;the combination of PML,periodic boundary and incident boundary extraordinarily simplified the calculation of the open space problems.
