摘　　要：溶液浓度是一个重要物理量。溶液浓度的变化会引起折射率变化。根据等厚干涉的原理,提出通过测量溶液的折射率来确定其浓度的光学方法。以NaCl溶液为例,测量误差低于3%。Solution concentration is an important physical index. The change of concentration can make the refractive index change. Based on the interference of isopach, an optical means was proposed by measuring the refractive index to determine concentration. Taking solution for example, measurement error is less than 3%.

关 键 词：溶液浓度 折射率 等厚干涉
