#1069 - [two_auctions] Add exercises and further reading

Files Updated

• ✏️ lectures/two_auctions.md
• ✏️ .translate/state/two_auctions.md.yml
• ✏️ lectures/_static/quant-econ.bib

⚠️ Target-Only Sections Removed

The following sections exist in the current translation but have no counterpart in the source document, so this sync removes them (the translation mirrors the source's structure). If the source deleted these sections, this removal is correct — merge as usual. If they are human-authored additions you want to keep, move them into a target-only file before merging (see adding content to a translated edition).

Criterion	Score

Formatting	8/10
Overall	8.9/10

Summary: 翻译整体质量高，准确传达了源文档中关于一价和二价密封拍卖理论、收益等价定理及相关练习的内容，数学公式和代码块格式保存完好，术语使用基本符合术语表要求。存在少量术语不一致（如'竞价者'/'投标者'/'竞标者'混用）及代码块中非原文内容（字体设置）的问题，但均为次要问题，不影响整体理解和文档编译。 数学公式和LaTeX格式在翻译中完整保留，未出现渲染问题 术语翻译基本遵循术语表，如'收益等价定理'、'贝叶斯纳什均衡'、'一价密封拍卖'等翻译准确统一 新增的练习（Exercises）和延伸阅读（Further reading）部分翻译流畅，忠实传达原文的数学推导和经济学直觉说明

Suggestions:

• [minor · formatting] lectures/two_auctions.md — Python代码 code cell: 翻译版本在代码单元中插入了字体设置代码（FONTPATH, mpl.font_manager等），这是源文档中没有的内容。虽然这可能是翻译项目的标准做法（用于支持中文字体渲染），但这属于对代码块内容的修改而非纯翻译。 → 如果这是翻译项目的标准字体适配做法，应在其他文档中保持一致；否则应保持代码与原文一致。
• [minor · fluency] lectures/two_auctions.md — ## 收入等价定理 表格标题行: 表格表头 '密封投标拍卖' 与英文源 'Auction: Sealed-Bid' 对应，但翻译省略了 'Auction' 一词，可能导致表头语义略有缺失，不过整体仍可理解。 → 可译为 '密封投标拍卖类型' 或保留原结构 '拍卖：密封投标'
• [nit · terminology] lectures/two_auctions.md — ## 第二价格密封拍卖 (正文段落): 正文中 '对竞价者$i$来说' 使用了'竞价者'，而文档其他大部分地方使用'投标者'或'竞标者'或'投标人'，术语在全文中不够统一（如'买家'、'投标者'、'竞标者'、'竞拍者'、'投标人'交替出现），虽然源文本本身在术语使用上也不严格一致，但在修改的章节内可以更加统一。 → 统一使用一个术语，如'投标人'或'竞标者'贯穿全文。

Structure Preserved	✅
Heading-map Correct	✅
Overall	10/10

Summary: The translation sync correctly applied all source changes (new exercises, further reading, revised explanatory text, and code simplifications) to the target document in matching positions while preserving structure and correctly updating the heading map.

Issues:

• In the Characterization of FPSB auction section, the translated bullet list uses the term '估值在投标者之间是私有的且独立的' which is a reasonable translation of 'valuations are private and independent across bidders' - no issue found here, but worth noting translation quality is good throughout
• New headings 'Exercises' and 'Further reading' were correctly added to translation.headings map as '练习' and '延伸阅读', replacing the now-removed 'References' key which is correctly absent since the source no longer has a References section
