摘要
在 Shalaby 最近的一篇简报中，给出了 标量场论度量算子的新一阶微扰计算。该结果声称是对 Bender、Brody 和 Jones 先前计算的改进，因为它是局域的。不幸的是，由于符号错误，Shalaby 的计算无效。

备注
2 pages, no figures. This comment replaces the previous comment on the Brief Report by Shalaby. In the previous comment we pointed out that Shalaby's calculation failed in all but 2 space-time dimensions. We have subsequently found additional errors which mean that the calculation is not valid even in that case
