How the sources were chosen来源是怎么选出来的

Each topic started from 100 candidate sources: official bodies, journals and preprint servers, research institutes, wires and major papers, trade press, named experts and communities. Each was scored once, out of 100: truthfulness 25 (peer review, official data, corrections policy, track record), authority 20 (primary source or recognised leader), fit with the topic 20, depth 15 (original data, reporting or analysis), monitorability 10 and activity 10 (both measured by a program on 2026-10-28). The 30 best of each topic are read; a source that cannot be read at all is never chosen. The list stays fixed: a broken source is reported on its topic page, not swapped automatically.

每个主题从 100 个候选来源开始：官方机构、期刊与预印本平台、研究机构、通讯社与大报、专业媒体、署名专家与社区。每个来源只评一次分，满分 100：真实性 25（同行评审、官方数据、更正制度、准确记录）、权威性 20（是否一手来源或公认顶级机构）、板块贴合度 20、专业深度 15（原始数据、原创报道或专业分析）、可监控性 10 与更新活跃度 10（这两项由程序在 2026-10-28 实测）。每个主题读取前 30 名；完全读不到的来源不能入选。名单固定：来源坏了只在主题页上标出，不自动替换。

Feed means the source's own RSS or Atom feed; page monitoring means a news page without a working feed, whose new article links are dated by when we first saw them; through PubMed means a journal whose own site blocks automatic reading. Every topic page is updated every six hours, and every item links to the original.

订阅源指来源自己的 RSS 或 Atom；网页监测指没有可用订阅源的新闻页，新文章链接的时间记为我们第一次看到它的时间；经 PubMed 指官网拦截自动读取的期刊。每个主题页每 6 小时更新一次，每一条都链接原文。
