论文摘要
在文献中的许多作品中，Kiselev时空被解释为“被精髓包围的黑洞”。解释不是真正可行的。例如，最近指出的是，在大多数时空建立的文章中，表达式“完美的流体”和“典型”都不当使用。因此，这与许多作者可能想到的那样重要。在这里，我们指出，Kiselev时空的原始推导也涉及使用太多的协调条件，再次强烈限制了其相关性。
In many works in the literature, the Kiselev spacetime is interpreted as the "blackhole surrounded by quintessence"; an interpretation not really tenable. For example, it has recently been pointed out that the expressions "perfect fluid" and "quintessence" are used improperly in most of the articles that build on that spacetime; hence it is not as relevant as many of those authors might think. Here we point out that the original derivation of the Kiselev spacetime involves the use of too many coordinate conditions as well, again strongly restricting its relevance.
