The substructure method was introduced to set up mathematical model of finite periodic composite structure,to solve its wave equation,and to derive its time-average power flows.

83C martensite aged at room temperature, indicating the existence of long-period ordered phase.

Study of active periodical structure′s controlling the direction of reflector electromagnetic wave;

A discrete certainty inventory model in a limited period is constructed without considering inventory lacking.

In this paper,a class of discrete deterministic zero lead time economic order quantity(EOQ) inventory models with limited period is studied.

Preparation and Optical Property of PZT Ferroelectric Thin Films/LaNiO_3 Thin Films Periodic Structure;

Theoretical analysis showed that under well specified conditions, electromagnetic slow wave can interact stationary with moving periodic structure,based on that the a working principle can be proposed for a class of MEMS motor and actuator.

As a result, waves can propagation along the periodic structures only with in specific frequency bands called the “Pass bands” and wave propagate is completely blocked with other frequency bands called the “Stop Bands”.
