The dehydration of Si-OH group under high temperature led to the transformation of abridging oxygen of OH to bridging oxygen, which caused the disappearance of structure defects and formed the long-range order structure of cristobalite. 高温下SiOH基团的脱水反应使硅藻土结构中以OH-形式存在的非桥氧变成桥氧,原来的结构缺陷消失,有利于降低方英石的形成温度;
The structure of compoud 4 consists of left-handed and right-handed helical chains that are connected through bridging oxygen atoms to form a two dimensional layer structure. 该化合物由四面体ZnO3N、假四面体HPO3相互连接形成左手和右手螺旋链,这些螺旋链之间通过桥氧原子连接形成二维层状结构。
In addition, illumination promotes the coupling of bridging oxygen atoms, suggesting that the Si-Si weak bonds are broken by photons during illumination. 同时,光照大大促进桥键氧原子的耦合,弱Si-Si键被打断。
Due to B ~ + ion-implantation, the position of O_ (( 1 (?) )) signals changes to higher binding energy and the relative concentration of bridging oxygen ions increases. O(1s)向高结合能变化且桥氧离子的相对浓度增加。
