Ir spectrum analyses have demonstrated that the structure mode of the substoichiometric silicon - 53 - abstrct oxide films ( sio ~ ) can be described as a mixture of rmm and rbm x at relatively low annealing temperature . the reaction , si - si ~ o4 ~ - - - ~ 进一步升高,由a工膜的xrd图矛前人的实验推车如t 800硅晶化自分急后增力,相应的a七减少, nc和a七。
Sio _ 2 nano particle has anti - rubs function is because sio _ 2 nano particle is very small and has the massive hydroxy , can forms the adsorption thin film within rub surface . so protected the solid surface improve the grease resistance to wear 纳米sio _ 2的抗疲劳机理是粒子很小且具有大量的羟基,可以在摩擦副间形成吸附薄膜,因而保护了固体表面,提高了润滑脂的耐磨性。
Numerical calculus and experiment for crystallization process of li2o - al2o3 - sio - p2o5 system glass indicated : size of crystallization grain can be controlled by forming residual glass phase with high melting point , and by this way we got transparent glass - ceramic 并依据理论分析的受控模型获得了小晶粒的透明微晶玻璃。讨论了通过主晶相和残余玻璃相的膨胀系数估算析晶量的方法。
