摘要翻译：
我在上一篇论文中指出，有一些环的实闭包*不是唯一的。在文[4]中，我们还讨论了存在唯一实闭包*的环的一些例子（主要是实闭环）。现在我们要确定更多的环类，其中实闭包*是唯一的。主要结果包括具有唯一实闭包*的区域和Baer正则环的刻划，以及正则环不必是F-环才能具有唯一实闭包*的一个例子。这里的主要目的是寻找实正则环的实闭包唯一性的刻画，它主要只需要环的素谱和实谱的信息。

英文摘要：
  It was pointed out in my last paper that there are rings whose real closure * are not unique. In [4] we also discussed some example of rings by which there is a unique real closure * (mainly the real closed rings). Now we want to determine more classes of rings by which real closure * is unique. The main results involve characterisations of domains and Baer regular rings having unique real closure *, and an example showing that regular rings need not be f-rings in order to have a unique real closure *. The main objective here is to find characterisation for uniqueness of real closure * for real regular rings that will primarily only require information of the prime spectrum and the real spectrum of the ring.
