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."/>     纳米非晶氮化硅键态结构的X射线径向分布函数研究
