Beijing ranks in first place in a list of cities that produced the most high-quality research in 2017, and nine other Chinese cities made the top 50, according to the Nature Index 2018 Science Cities, a supplement of the British scientific journal Nature, published on Thursday.
根據英國科學期刊《自然》週四發佈的《2018年自然指數-科研城市》，北京在2017年科研城市中排名第一，另有9箇中國城市進入前50名。
The list sorted out and ranked 200 cities worldwide by their 2017 fractional count, a metric for the share of contributions to the authorship of articles in 82 high-quality research journals.
該榜單根據2017年全球200個城市的科研分數排名，使用在82家高質量研究期刊發表論文的作者比例作為衡量指標。
To calculate the fractional count, all authors are considered to have contributed equally to the article. The maximum combined fractional count for any article is 1.0.
為了方便計算分數，認為所有作者對論文的貢獻相等，任何文章的最大得分都是1.0。
The 2017 fractional count for Beijing reached 2,143.53, topping the list.
北京在2017年的分數達到了2143.53，位居榜首。
The table accompanying the list also shows that authors in Beijing produced 4,396 articles in 82 high-quality research journals and accounted for 23.5 percent of the papers published by China on these journals.
從排行榜中還可以看出，來自北京的作者在82種高質量研究期刊上發表了4396篇文章，佔中國在這些期刊上發表論文的23.5%。
However, other Chinese cities -- like Nanjing at 12th place, Wuhan at 19th and Guangzhou at 25th -- are rising rapidly in scientific research, resulting in the declining share of Beijing in China’s output for six consecutive years.
然而，中國其他城市——如南京排名第12位、武漢排名第19位、廣州排名第25位——在科研方面增長迅速，導致北京在中國總分中所佔的份額連續6年下降。
Shanghai at seventh is the other Chinese city among the top 10. Hong Kong, Hefei, Hangzhou, Tianjin and Changchun were also ranked between the 21st to 50th places.
上海是中國另外一個躋身前10名的城市，排名第七。香港、合肥、杭州、天津和長春也排分別在第21位到第50位之間。
