摘要：

The renormalised value of [phi(2)] is calculated for a massless, conformally coupled scalar field in the Hartle-Hawking Vacuum state. This quantity is used as a measure of vacuum polarization induced by the presence of gravitation. It is also a step towards the calculation of the gravitational back reaction of the field in a black cosmic string spacetime which is asymptotically anti-de Sitter and possesses a non constant dilaton field. It is found that the field is divergence free throughout the spacetime and attains its maximum value near the horizon.
