The system, including spectra data base, knowledge data base and reasoning engine, is based on the characteristics of the proton NMR spectra of polymers and the spectra interpretation experiences of specialist.

文摘The varying temperature pulse protonquilibrium moisture content of several Chinese andNMR method was adopted to determine the eAustralian coals. The pulse proton NMR spectrometry is sensible to the hydrogen at different physical state which occurs for water when temperature changes through 273 K. The equilibrium water,with some interactions to the coal surface ,will not transform from one phase to another while the free water does. The measured results are reasonable comparing to the conventional gravimetric method.
