主　　题：Soil otal nitrogen near-ifrared spectroscopy improved moving window partial least squares stability 

摘      要：The selection of stable wavebands for the near-infrared(NIR)spectroscopic analysis of total nitrogen(TN)in soil was accomplished by using an improved moving window partial leastsquares(MWPLS)method.A new modeling approach was performed based on randomness,similarity and stability,which produced an objective,stable and practical *** on the MWPLS method,a search was in the overali scanning region from 400 to 2498 nm,and the optimal waveband was identified to be 1424 to 282 nm.A model space that includes 41 wave-bands that are equivalent to the optimal waveband was then *** public range of the 41equivalent optimal wavebands was 1590 to 1870 nm,which contained suficient TN *** wavebands of 1424 to 2282 nm,1590 to 1870nm,and the long NIR region 1100 to 2498 nmall achieved satisfactory validation ***,the public waveband of 1590 to 1870 nm hadonly a minimum number of wavelengths,which significantly reduced the method *** equivalent wavebands serve as guidelines for designing spect roscopic *** could address the restrictions of position and the number of wavelengths in instru-ment design.
