When corresponding sports state is as follows for the sliding rolling of quantization:
n2=0, n2d2=0, S=2 are simple sliding,
n1d1=n2d2, S=0 is pure rolling,
n1d1≠n2d2≠ 0, S ≠ 0 and S ≠ ± 2, for the rolling containing sliding；
Preferably, the method further include: collect the abrasive dust and/or waste liquid of the secondary output of friction in friction process, and clear up
Sample wheel carries out subsequent analysis and evaluation to the abrasive dust on emery wheel, then to the polishing scratch of abrasive dust and material surface to be assessed.
