The quantum corrections to the entropy of the static black holes with a global monopole or a cosmic string are studied by two methods:the brick wall and the Euclidean path *** we ignore the usual contribution from the vacuum surrounding the system,then the two approaches give the same *** quantum corrections for the static black holes consist of two parts:One is quadratically divergent term which takes the geometric *** other is a logarithmically divergent term which is not proportional to the horizon *** renormalization of the quadratically and logarithmically divergent is also investigated.

The thermodynamics of a static dilaton black hole is investigated by Euclidean path *** interesting results are obtained:(Ⅰ)Although the temperature,heat capacity and chemical potential have different forms as compared to general classical static charged black hole,the Bardeen-Carter-Hawking thermodynamical laws are valid for the black hole.(Ⅱ)The entropy and area of the event horizon are zero but the energy,temperature and surface gravity are non-zero for extremal case(rh=2M=b).(Ⅲ)The charged black hole does not possess second order phase transitions as the Reissner-Nordstrom black hole since its heat capacity is negative.(Ⅳ)The action is equal to the entropy,and both quantities coincide with one quarter of area of the event horizon.

The late-time evolution of the phantom scalar perturbation is investigated in the spacetime of a four-dimensionai spherically symmetric static black hole. It is revealed that the asymptotic tail of the phantom scalar field is dominated by the growth behavior t-（l＋3/2）eμt, which depends on the multipole moment l and the field moss but is independent of the mass M and charge Q of the black hole. This growth behavior is in strong contrast to the decaying tall of the usual massive scalar perturbation and shows that the external phantom scalar perturbation is unstable in the spherically symmetric static black hole spacetime.

The absorption cross section of the static Einstein-Maxwell dilaton axion （EMDA） black hole for scalar particles is investigated. It is shown that the ratio of the absorption cross section of the EMDA black hole to that of the Schwarzschild black hole decreases as the absolute value of the dilaton increases, and it becomes zero as the dilaton tends to its extremal value. It is also shown that the absorption cross section decreases as both the v and the absolute value of the dilaton increase, and it decreases as the mass of the particle decreases.

The statistical-mechanical entropy of the stationary axisymmetric Einstein-Maxwell dilaton-axion black hole is investigated by using the “brick wall” model in which the original Dirichlet condition is replaced by a scattering ansatz for the field functions at the event horizon and regularized with the Pauli-Villars scheme. It is also shown, for the Kerr black hole, that the statistical-mechanical entropy obtained from our derivation coincides with the one-loop correction to its thermodynamical entropy obtained by the conical singularity method.

The Brown-York quasilocal energies of some static charged dilaton black holes are calculated, and then the validity of Martinez's conjecture is explored in string theory. It is shown that the energy is positive and monotonically decreases to the ADM mass at spatial infinity, and the conjecture that the Brown-York quasilocal energy at the outer horizon of black hole reduces to twice of its irreducible mass is still applicable for the static charged black holes in string theory. The result is different from Bose-Naing's one.
