摘要：

The Gaussian theory of superconducting fluctuations in an uniform magnetic field is presented above the H-c2 line, for an anisotropic superconductor. The situation of an arbitrary orientation of the field is investigated by means of a scaling transformation. The specific heat and the diamagnetic susceptibility are calculated. In particular the fluctuation torque is compared to the mean-field one just below H-c2 and in the London regime. A comparison is made with existing experiments on specific heat and torque in high-T-c compounds.
