Describes the evaluation process for the determination of parameters from the linear regions of the material probability curve, which is the Gaussuan representation of the material ratio curve. These parameters are meant to aid in the assessment of tribological behaviour, for example of lubricated, sliding surfaces, and to control the manufacturing process.
