ln order to find a practical application of terahettz spectroscopy, we conducted a spectral analysis of the aqueous solution. We could confirm that analytical method such as chemometrix is beneflcial technique to estimate concelltration of solute in a simple aqueous solution. It was also successful in monitoring the change in hydration of the polymer and water molecules. Additionally, we concluded when measuring the changc of the solute in spectroscopy with a sllicon rod, we need temperature correction method

为了找到太赫兹光谱的实际应用，我们对水溶液进行了光谱分析。我们可以证实，诸如 chemometrix 之类的分析方法是估计简单水溶液中溶质浓度的有益技术。它还成功地监测了聚合物和水分子的水合变化。另外，我们得出结论，当用硅棒测量光谱中溶质的变化时，我们需要温度校正方法
