Symmetrical invariant transformation of localization length in one-dimensional randomly-perturbed periodic structure;

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

The periodic perturbations on oscillatory states of CSTR - BZ reaction is studied by alternating flow rate in the experiment.

The chaotic motion of a planar 2R robot was suppressed efficiently by applying periodic perturbation.

This paper investigates the orbits of sub-harmonic and chaos in power system under periodic and quasi-periodic perturbation.

In the track- following servo system of an optical disk drive, the eccentricity of optical disk will cause periodic disturbances on TE(tracking errors) signals.

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”.

Study on Mechanical and Electromagnetic Dynamic Characteristics of Materi/als with Periodic Structures;

After analyzing the coefficient matrices of periodic structures resulted from the finite element method(FEM), a FEM with partial assemblage was put forward.

In this paper, the problem of the superposition of two film systems with periodic structures is discussed theoretically, reaching a conclusion that the cut off of the superposition has non-interference characteristics of each film system.
