我必须用 RevTex 4.1 编写一篇论文以供提交，但在参考书目页面方面遇到了麻烦。
每当我引用一篇尚未在期刊上发表的论文时，就像 arXiv 上的大多数论文一样，我会在参考书目页面的相应行中看到多余的逗号。
我确信这是一个愚蠢的错误，但我在 Google 上找不到答案，因此提出了这个问题。

@article{Anand2009,
abstract = {Trust lies at the crux of most economic transactions, with credit markets being a notable example. Drawing on insights from the literature on coordination games and network growth, we develop a simple model to clarify how trust breaks down in financial systems. We show how the arrival of bad news about a financial agent can lead others to lose confidence in it and how this, in turn, can spread across the entire system. Our results emphasize the role of hysteresis -- it takes considerable effort to regain trust once it has been broken. Although simple, the model provides a plausible account of the credit freeze that followed the global financial crisis of 2007/8, both in terms of the sequence of events and the measures taken (and being proposed) by the authorities.},

我究竟做错了什么？
谢谢您的帮助，如果需要更多信息请告诉我。
答案1
该领域journal是必需的类型条目的字段@article。由于相关条目似乎仅在arxiv预印本中可用，因此您可能不应该@article为其使用条目类型。相反，请考虑使用 catch-all@misc条目类型。（您也可以尝试@unpublished。）

正如我所料，我的问题的答案非常简单。
供将来参考，只需用@unpublished 替换@article，问题就解决。
