对于共形耦合标量场，我们计算史瓦西时空中视界外部区域的哈特尔-霍金真空的重整化值。我们发现 /sub ren/ 的模和表达式自然地分为两部分，一部分具有与 Whiting 和 Page 的近似表达式一致的简单解析形式，另一部分很小。我们对余数进行数值评估，并提供其解析近似。我们的结果与 Fawcett 先前给出的结果一致，但更加准确。
For a conformally coupled scalar field we calculate the renormalized value of for the Hartle-Hawking vacuum in Schwarzschild space-time for the region exterior to the horizon. We find that the mode-sum expression for /sub ren/ separates naturally into two parts, a part that has a simple analytic form coinciding with the approximate expression of Whiting and Page, and a remainder that is small. We evaluate the remainder numerically and also provide an analytic approximation to it. Our results agree with, but are substantially more accurate than, those previously given by Fawcett.
