derivative spectrum
1.D by using the first derivative spectrum and REP, and the properest models were index(R2=0.9487)and parabola (R2=0.9392) respectively.
2.Application of second derivative spectrum prepares in quantification measuring glucose-6-phosphate and fructose-6-phosphate using a FTIR/ATR method
3.The composition of coordination compound in solution and resin respectively is Eu: Ars Ⅲ= 1:1(Solution phase and Eu:Ars Ⅲ=1:6(resin phase).Positions of frist derivative spectrum -for resin compoand are 576.0(+)um.1.599(+)D1:655.2(--) urn,2.114 (M) D1.
4.After measuring some spectral curves of typical plants a-round Dexing copper mine by spectroradiometer and estimating the position of red edge from hyperspectral data by derivative spectrum technology,it is show that the red edge of plant shifts from originally red to shorter blue.
5.In the ternary color system of 2,6,7-trihy-dro salicylfluorone-Ge( Ⅳ )-OP containing 0. 72 mol/L H2SO4 and 3. 0 mol/L H3PO4, the molar responsive coefficient of the 4th-derivative spectrum by compressing X-factor is 1. 89 × 105 L · mol-1· cm-1 (12. 4 times as high as );
6.Simultaneous Determination of Aspirin,Phenacetin and Caffeine in Compound APC by Derivative Ratio UV Adsorption Spectrum Method
7.The authors have analyzed the quality of nonphotosynthetic background-soil spectra,found that the first derivative calculation of mixed spectrum could compress the signal of soil spectra in a large extent,Due to this reason the estimation of vegetation variables such as LAI,S Apar seems to well correspond to the real results It is very useful for us to apply imaging spectrometer to monitoring environment
8.STUDY ON THE INTERACTION BETWEEN PHOTORADIATION-HEMATOPORPHYRIN DERIVATIVE AND LIPOSOME WITH SPIN LABEL AND ESR SPECTRUM
9.The interaction between photoradiation-hematoporphrin derivative (HPD) and liposome was studied with fatty acid spin label and ESR spectrum by white light, infrared laser and ultraviolet laser. It was found that photoradiationHPD increased the permeability of the liposome largely.
10.The NIRS quantitative an alysis model was developed for measuring MBM content in fish meal by using parti al least squares (PLS). The initial spectrum was pretreated by standard normalized variate (SNV) , 7 point smoothind and one derivative respe ctively.
