摘要：
Thermal properties of NaV2O5 reflect the complex character of the phase transition at T-C similar to 34 K which includes the charge ordering, the lattice distortion and the spin gap formation in magnetic excitations spectrum. The specific heat shows sharp lambda-type anomaly at T-C, the heat conductivity strongly increases below T-C, and the thermal expansion exhibits highly anisotropic behavior below T-C.
