摘要：
The crossover phenonena in the normal phase of the high-T(c) superconductor are discussed from the viewpoint of the RVB theory. The fluctuations of the spinon pairing and the holon condensation are taken into account and the deviations of transport properties from those of the ''strange metal'' region are clarified. These theoretical predictions are in qualitative agreement with the recent experiments while it is difficult to explain them in the Fermi liquid picture.
