摘　　要：THz射线是介于微波和红外光之间的电磁波,可被用于图像分析系统,实现对物体的无损检测、分析蛋白质等大分子的三维乃至四维结构。本文介绍了THz射线的概念、特点、应用及其发展前景。THz-ray is an electro-magnetic radiation ranging between microwave and infrared region. It can be usedin building a terahertz spectrometer due to its stronger nonlinearity and longer wavelength etc. for nondestructivedetection and analysis of the third and the fourth dimensional structure of protein. The definition and characteristicsof THz-ray, the significance of THz-ray research, the potential applications and the development trend are described.
