Controlling wave propagation with spatial material distribution has important applications such as stealth technology, structure impact protection and super-resolution imaging.In recent years, based on form invariance of Maxwells equation, transformation method provides a direct way for finding material spatial distribution when a wave pattern is prescribed.In this talk we will reinterpret the transformation method by spatial deformation, and with the assumption of local affine transformation, the transformation methods are formulated for electromagnetic, acoustic and elastic waves in a unified manner.We also present the design method for metamaterials which are necessary for wave control, and examples are also given to illustrate the wave control methodology.

本文以陶瓷基础料、抛光砖废料、普通硅酸盐水泥、三聚磷酸钠为原料,制备出发泡效果良好、连通孔率高的多孔吸声材料,在160～2000Hz的平均吸声系数为0.255,抗折强度3.93MPa,真气孔率64.45％,显气孔率42.05％,容重0.89g/cm3.通过实验进一步分析影响材料吸声性能的因素极其影响规律：随着材料厚度的增加,第一共振频率往低频方向移动,低频声波的吸收显著升高；随着容重增加,材料的低
国际标准ISO 13006：1998《陶瓷砖-定义、分类、性能和标记》是我国陶瓷砖国家标准GB/T 4100-2006《陶瓷砖》的基础，采用国际标准或国外先进标准是我国一项重大的技术经济政策，符合《中华人民共和国标准化法》中关于"国家鼓励积极采用国际标准"的政策。但国际标准也有很大的局限性，国际标准也并不代表国际先进水平，甚至达不到国内水平，不能盲目采用。本文分析了国际标准ISO 13006的技术
艺术陶瓷的仿冒不仅损害了作者的创作热情，还扰乱了正常的艺术陶瓷市场，严重威胁艺术陶瓷可持续发展。为解决现代艺术陶瓷的防伪问题，本文提出以现代艺术陶瓷的材料特性为特征判定对象，采用无损检测技术检测，辅以外形尺寸、重量等宏观参数，确定艺术陶瓷的"身份标识"，使其成为该陶瓷的唯一身份标识，建立数据库并予以身份授权和保护。若干年后，可通过"身份标识"验证，确定该艺术陶瓷的真伪，从而在技术上实现现代艺术陶瓷
