The morphological analysis and chemical characterization of the worn surfaces via scanning electron microscopy, laser scanning microscope, and X-ray photoelectron spectroscopy reveal that under titrimetric water lubrication, the hBN in Si3N4-hBN spalled off during the wearing tests and the spalled pits formed on the wearing surface of Si3N4-hBN, and then the debris dropped into the pits to react with water, thus a tribochemical film formed on the wearing surface. The formation of the tribochemical film facilitated smoothing the surfaces of Si3N4-hBN and Si3N4 to create a fine lubrication environment.

在滴定法水润滑条件下，磨屑不易被水带走，当Si3N4-hBN与Si3N4配副摩擦时，由于Si3N4-hBN摩擦面上hBN偏聚区域发生脆性断裂和剥落而形成剥落坑，磨屑在剥落坑中堆积并氧化、水解，反应产物富集于剥落坑中，进而在摩擦表面形成含B2O3和SiO2的摩擦化学反应膜，从而保护了Si3N4-hBN和Si3N4摩擦面，使其变得光滑，为发生流体润滑提供了条件。

Harbin Institute of Technology, Harbin 150001, China）Abstract: The modified layers by O2-PBII technology on Ti6Al4V alloy surface were studied using X-ray photoelectron spectroscopy.

通过溶液光谱实验说明稳定剂有利于染料J聚集体的稳定性；反射光谱实验和光谱曝光实验证明稳定剂与染料的添加次序对乳剂的光吸收有很大的影响，只有稳定剂在染料之后加才有利于染料在AgCl颗粒上排列整齐形成J聚集态及其光吸收；ESR实验结果说明稳定剂的加入可以降低染料正空穴的浓度及其衰减速率，使乳剂中染料正空穴减少，从而抑制了染料正空穴引起的减感作用。因此可以认为稳定剂的超增感作用：一是有利于染料形成J聚集态及乳剂的光吸收；二是降低染料正空穴的浓度，从而抑制染料的减感。同时还提出了染料与稳定剂的增感吸附模型。
