Public Understanding of Science is an interdisciplinary journal serving the scholarly community and practitioners. This article reports an analysis of the readability and jargon in articles published in Public Understanding of Science throughout its almost three decades of existence to examine trends in accessibility to diverse audiences. The accessibility of Public Understanding of Science articles published in 1999/2000 (47), 2009 (49) and 2019 (65) was assessed in terms of readability and use of jargon. Readability decreased and use of jargon increased between 1999 and 2000 and the two following decades for empirical and non-empirical papers, and all parts including the abstracts. An analysis of rare words shows that most are not part of the general academic vocabulary or disciplinary jargon, but rather words that appeared only in one article. Public Understanding of Science has moved away from everyday language. This does not mean it is incomprehensible to its scholarly readership, but may have consequences to other audiences such as practitioners.

三年来，在公众对科学论文的理解中使用的行话。

《公众对科学的理解》是一份服务于学术界和从业者的跨学科期刊。本文报告了对发表在《公众对科学的理解》上近三年来发表的文章的可读性和行话的分析，以检查不同受众的可访问性趋势。1999/2000 (47)、2009 (49) 和 2019 (65) 发表的《公众对科学的理解》文章的可访问性根据可读性和行话的使用进行了评估。从 1999 年到 2000 年以及接下来的两个十年，经验性和非经验性论文以及包括摘要在内的所有部分的可读性下降，行话的使用增加。对稀有词的分析表明，大多数不是一般学术词汇或学科术语的一部分，而是只出现在一篇文章中的词。公众对科学的理解已经远离日常语言。这并不意味着它的学术读者无法理解它，但可能会对其他受众（例如从业者）产生影响。
