摘要
本文介绍了根据光纤弯曲损耗测量溶液浓度的原理和方法。利用双光路光纤结构和数据拟合技术，对盐水的浓度进行实际测量。结果表明此技术可以应用于微区浓度测量，并具有较高的精度。
The principle and method of measuring liquid density is presented in this paper according to double optical routes stracture and data combination technique to detect the density of salt water.The result shows that it is applicable to detect liquid density of microregion and has high accuracy within the limits.
