基于几何性质，同时适用于克尔度规和Wahlquist度规，我们认为克尔度规是Wahlquist完美流体解的真空子情形。克尔-纽曼度规是克尔度规的物理上优选的带电推广。我们讨论的几何属性使这个度量如此特殊，并要求一个收费的推广Wahlquist度量满足类似的属性应该存在。这是Wahlquist-Newman度量，我们在本文中明确提出。这一系列的指标有八个基本参数，并包含克尔纽曼德�，−→ ↓ ↓？↓？?↓？
Based on a geometrical property which holds both for the Kerr metric and for the Wahlquist metric we argue that the Kerr metric is a vacuum subcase of the Wahlquist perfect-fluid solution. The Kerr-Newman metric is a physically preferred charged generalization of the Kerr metric. We discuss which geometric property makes this metric so special and claim that a charged generalization of the Wahlquist metric satisfying a similar property should exist. This is the Wahlquist-Newman metric, which we present explicitly in this paper. This family of metrics has eight essential parameters and contains the Kerr-Newman-de � � , −→ ↓ ↓ ? ↓ ? ? ↓ ?
