3N4 and there exist a large number of Si dangling and unsat-urated bonds. NANO-SNS has an nonty-pical covalent structure that contains lots of unsaturated and dangling bonds. This bond structure is different from the saturated covalent bond structure of traditional Si3N4.Due to the unsaturated character of the bond coordination numbers, the molecular form of NANO-SNS should be written as Si3-xN4-y. The appearence of strong polarity of NANO-SNS is closely related to unsaturated and dangling bonds."/>     A STUDY ON BOND STRUCTURE OF NANOMETER-SIZED AMORPHOUS SILICON NITRIDE SOLIDS IN TERMS OF X-RAY RADIAL DISTRIBUTION FUNCTIONS
