用SnO_2薄膜测水中甲醛的光纤传感方法

An Optical Fibre Sensing Method for Measured Formaldehyde in the Water Using SnO_2 Film

用 SnO_2薄膜作光纤传感材料,测量水中的甲醛含量,所测范围为6%体积浓度以下,并解释其机理。

The SnO_2 film is used as optical fibre sensing material.Formaldehyde is measuredin the water,measuring range are from 0% to 6%(volume concentration)and the sensing me-chanism is explained.
