When the content of 3wt% silane-treated barium glass filler reached 40wt%, simultaneously added 3wt% nano-sized silic into resin matrix, the experimental composite obtained optimal mechanical properties and suitable viscosity. 5.

当3wt%硅烷偶联剂处理后的钡玻璃填料在树脂体系中含量达到40wt%，同时加入3wt%的二氧化硅纳米填料，可以获得较佳的复合树脂力学性能和适合的树脂体系粘度。

Results The relationship tallied with negative linear correlation between the K-M function values of the isolated OH-groups on the barium glass surface and the concentrations of γ-MPS.

结果钡玻璃表面游离羟基的K-M函数值与γ-MPS质量分数存在负相关的直线相关关系。

Conclusions: The absorption behavior of a silane coupling agent γ-MPS was revealed on the barium glass surface, which provided the theoretical basis for the development of dental composite resins.

结论：揭示了硅烷偶联剂γ-MPS在钡玻璃表面的吸附特征，为新型复合树脂的研究和开发提供理论依据。

Results: When the concentration of γ-MPS was low, the γ-MPS molecules oriented either parallel or perpendicularly onto the barium glass surface.

结果：γ-MPS低浓度时，分子在钡玻璃表面的吸附既有垂直取向又有平行取向；

Each γ-MPS molecule occupied 0.21 nm~ 2 when the monomolecular coverage was formed on the barium glass surface.

γ-MPS在钡玻璃表面单分子层覆盖所占据的面积为每分子0·21nm2。
