中文摘要:

      测量不同分辨率下、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.

英文摘要:

      We analyze the different chloroform gas concentration with Fourier Transformation Infrared spectrum (FTIR) under the different resolution. Combined the US environmental protection bureau (EPA) in the database data with least squares equation to obtain the chloroform concentration under the different resolution, as well as the coefficient of correlation and the relative error. The resolution has some influence on its precision. It is very important to choose the appropriate resolution to enhance the compound precision.
