摘要
测量了不同分辨率下不同浓度氯仿气体的傅里叶变换红外光谱(FTIR)。利用美国环境保护局(EPA)数据库中的数据,通过最小二乘拟合得到不同分辨率下的氯仿浓度,以及线性拟合度和相对误差。分辨率的大小对其计算精确度有一定的影响,选择合适的分辨率对于提高化合物的精确度至关重要。
Fourier transform infrared （FTIR） spectra of chloroform gas with different concentrations were measured under different resolutions. Combined with data from the environmental protection bureau （EPA） database of America, the chloroform concentrations were obtained under different resolutions with least squares fitting, as well as the coefficients of correlation and the relative errors. The resolution has some influence on its precision. It is very important to choose appropriate resolution to enhance the detection precision of compound.
