摘要：

The interlayer spacing d002, X-ray diffraction profiles of the (110), (112) and (006) lines and the dependence of the electrical resistivity, Hall coefficient and transverse magnetoresistance at liquid nitrogen temperature on d002 were measured for pyrolytic carbons with a wide range of d002. For selected samples the temperature dependence of the resistivity and magnetoresistance were measured from 2.4 to 290 K in magnetic fields up to 3 T. The d002 values for which discontinuities in slopes or sign reversals occur for each of the resistivity, magnetoresistance and Hall coefficient against d002 curves are common, and are 3.367, 3.380 and 3.420 angstrom. These values are identical to those for which stepwise changes occur in the interlaver spacing observed in annealing studies of cokes and pyrolytic carbons, and in fast-neutron irradiation and grinding of graphite.
