FIELD: inspection of degree of lacing of polyethylene. ^ SUBSTANCE: tested and reference samples are placed into resonator of electron paramagnetic resonance spectrometer, spectrum of absorption of electron paramagnetic resonance is recorded. Amplitude of derivative and width of absorption line of tested and standard samples is found from spectrum recorded correspondingly to subsequent determination of degree of lacing from formula K=I'DeltaH2mref/I'refDeltaH2 refm, where I' and I'ref are amplitudes of derivative of absorption line of tested and reference sample, DeltaH and DeltaHref is width of absorption lines of tested and reference samples, m and mref are masses of tested and reference samples. ^ EFFECT: improved precision of inspection; simplified method of inspection; improved efficiency of operation. |
