Solvothermal synthesis and diffuse reflectance spectra of k2mnsnte 4的溶劑熱合成和反射光譜研究
Solid state synthesis , crystal structure and diffuse reflectance spectra of k4sn3se 晶體結(jié)構(gòu)和反射光譜研究
53 maize standard samples diffuse reflectance spectra were collected from 4000cm - 1 ~ 10000cm - 1 at 8 cm - 1 resolution on perkin - elmer spectrum one nts near - infrared instrument at different energy level . 3 samples were scanned 10 times repeatedly at 100 % , 76 % and 34 % energy level for energy variance analysis 結(jié)果表明,隨著儀器能量降低,模型相對(duì)標(biāo)準(zhǔn)偏差( rsd )有增大趨勢(shì),儀器相對(duì)能量從100衰減到18后,模型預(yù)測(cè)值rsd從2 . 5增至4 . 72 。
