摘要

由于体表分泌物中氯化钾的含量与人体生理状态有直接关系

研究了快速检测人体正常体温36.5℃下体表分泌物中氯化钾含量的方法。首先

基于近红外光谱法测量了标准氯化钾溶液的浓度。然后

对钾离子近红外光谱进行分析

采用最小二乘法对吸收峰进行拟合。分析拟合结果显示

最小二乘法拟合的决定系数(

)能够达到96.28%

可以表达体表分泌物中氯化钾的吸收光谱随温度和浓度变化的规律。研究结果表明

利用近红外光谱对体表分泌物中氯化钾成分的定性分析较为清晰地展现了近红外光谱吸收峰与体温变化和氯化钾浓度的关系:同一温度下氯化钾的浓度越大

吸收峰越强;同一氯化钾的浓度下温度越高

吸收峰越强。

Abstract

As KCl composition at human body surface has a direct relationship with the human physiological condition

a detection method for the KCl composition of skin secretion at the normal body temperature 36.5℃ was explored

The near infrared spectroscopy was adopted to measure the solution concentration of KCl. After analyzing the solution concentration of K

based on near infrared spectroscopy

the least square method was used to fit the absorption peak. Fitting results show that the absorption spectrum for KCl composition of skin secretion varies with temperature and KCl concentration

and the determination coefficient of least square method (

) can reach to 96.28%. The results indicate that KCl composition qualitative analysis for skin secretion based on near infrared spectroscopy can clearly give the relationship between the absorption peak and solution concentration of KCl near the normal body temperature. At the same temperature

the absorption peak gets bigger with increasing the solution concentration of KCl . At the same solution concentration of KCl

the absorption peak gets bigger with increasing the temperature.
