摘　　要：声子晶体是一种具有弹性波带隙的周期性新型复合材料,它具有特殊的带隙特性和声学特性,具有潜在应用价值.文章简要分析了一维声子晶体的三种基本结构及其三种简化模型,对一维声子晶体在隔音应用和车内噪声控制两方面的研究成果进行概述,为深入一维声子晶体在噪声控制方面的应用研究提供依据.The phononic crystal is a kind of new periodic compound material with flexible band-gap, special band-gap and acoustic properties which has potential application value. The paper briefly analyzes three basic structures and three simplified models of one-dimensional phononic crystals and generally describes the research findings in its application to sound insulation and noise control in the car which offer a basis for further research on the application of one-dimensional phononic crystals.
