Thus, the optical constants of metallic films and contamination layers on its surface could be determined precisely by using the SPW technique.
因而利用SPW技术可以精确地确定金属膜及其表面污染层的光学常数。
the grey relational grades among weight contamination, wear particle content, wear severity index and wear metallic elements ( fe, cu) were calculated based upon the grey system theory through contamination degree test, spectrometry and ferrography analysis.
通过对机械设备在用润滑油的污染度检测与光、铁谱分析试验,运用灰色系统理论,计算了重量污染度与磨粒浓度以及磨损金属元素(Fe,Cu)之间的灰色关联度。
