摘要

用不同的氯化钠浓度测试了简易时域反射仪器链的有效性。该系统布局简单、经济，软件界面友好，测量速度快。采用一种创新的方法对这类信号进行统计分析，考虑了波形的多元分析，取代了传统的数学理论。氯化钠估计的测定系数较好，简单线性回归的R2为0.942 (RMSE 0.18 g/100ml)， PLS分析的R2为0.983 (RMSE 0.10 g/100ml)。结果表明，一种廉价、快速、易于使用的仪器链对于食品参数的测定是非常有前景的。

Simply Time Domain Reflectometry system for food analysis

Effectiveness of a simple Time Domain Reflectometry instrumental chain was tested by using different sodium chloride concentration.The layout is quite simple and economic, the software user friendly and the measurements rapid.An innovative approach for the statistical analysis of these kind of signals was implemented, accounting for multivariate analysis of the waveform, replacing the traditional mathematical theory.Good results in terms of coefficient of determination for sodium chloride estimation were obtained with R2 0.942 (RMSE 0.18 g/100ml) for simple linear regression and R2 0.983 (RMSE 0.10 g/100ml) for PLS analysis.The results obtained show how a cheap, rapid, and easy to use instrumental chain can be very promising for determinations of foodstuff parameters.
