In this thesis, two chemical structural models were constructed based on several structure parameters derived from FTIR and 13C NMR data, which were processed by curve-fitting and curve-resolved. Modified models were obtained by simulation oftheir molecular vibration spectra using Cerius 4.6/IR module andthe structural parameters from 13C NMR. Potential energy, bondenergy and non-bond energy of the minimum-energy conformations of coal macromolecules were calculated by molecular mechanics calculation and molecular dynamics simulation. These results demonstrate the importance of hydrogen bonding and van der Waals interactions in the formation and stabilization of coal macromolecular structure, and a strongest tendency of hydrogen bonding interactions to increase with the coal molecules but the Coulombs force.

The results show that single structure parameters (width and depth of flow path/passage, and height, and angle of dentations) are local and difficult to represent the anti-clogging ability of emitters. Characteristic structure parameters(minimum size of cross section, hydraulic radius and dentitions spacing) can represent the anti-clogging ability of emitters in a sense. There are anti-clogging critical values under the test. Rated flow Qr and the ratio of diameter of labyrinth passage to diameter of particle η are well cor related to the anti-clogging ability and have anti-clogging critical values too.
