摘要
系统而详细地介绍了近年来液体折射率测量上经常采用的5种方法——激光照射法、衍射光栅法、光纤杨氏干涉法、掠面入射法和CCD测量法,并分别对其原理和特点进行了分析,这些测量方法都具有原理简单易懂、测量设备和操作方法简便可行的特点．
Five measuring methods of refractive index of liquid are introduced. It includes method of irradiation of laser, method of diffraction grating, method of optical fiber Young＇s interference, method of Abbemat refractometer, and method of measuring by CCD. All of these methods are simple for operation, and their principles are easy to understand. The characters of each method are also analysed.
