Problems solved by technology

The selection of the modeling set should have a certain representativeness, so in the prior art, the sample set always tends to have a large sample size (and the concentration range should be wide); but whether the selection is correct (sample size, sample SD value and model effect) is rarely studied

Abstract

The invention discloses a near-infrared quantitative detection model parameter selection method and a quantitative detection method, based on modeling of gentiana straminea or meconopsis integrifolia, the parameter selection method comprises a modeling set sample selection step, and the modeling set sample selection step comprises the following sub-steps: setting a modeling set sample size; when modeling based on gentiana straminea maxim, the sample size of the modeling set is 80-100; when modeling is carried out based on meconopsis integrifolia, the sample size of the modeling set is 110-130. Compared with the prior art that a sample set always tends to have a large sample size, according to setting of the sample size of the modeling set, when modeling is carried out based on gentiana straminea, the sample size of the modeling set ranges from 80 to 100; when modeling is carried out based on meconopsis integrifolia, the sample size of the modeling set is 110-130, so that the quality of a subsequent model is the best.

Description

technical field [0001] The invention relates to the field of near-infrared detection, in particular to a parameter selection method and a quantitative detection method of a near-infrared quantitative detection model. Background technique [0002] Near Infrared (NIR) is an electromagnetic wave between the visible light region and the mid-infrared region. Its wavelength range is 0.8-2.5m. The NIR spectrum shows the composition of X-H (N-H, O-H, C-H, etc.) inside the substance molecule frequency and octave absorption [1]. The near-infrared spectral region was discovered by astronomer William Herschel in 1800. Compared with the mid-infrared spectral region, it was discovered earlier and its application was also earlier. However, the near-infrared absorption intensity is weak and the spectral information is superimposed seriously, which was limited by the theory and technology at that time. With the level of development, the research focus has gradually shifted to the mid-infrar...
