摘要
利用全最小二乘法，对丙酮中所含红外光谱重叠严重的苯及甲苯所测数据，自编程序，在计算机上进行处理，所得结果相对误差均小于６％，优于最小二乘法．
A new method based on the total least squares is proposed. Made use of it combined with infrared spectroscopy to determine benzene and toluene in acetone whose infrared spectrums are overlapped.The results display that the method of total least squares is better than the method of the least squares.
