Summary: 三篇文档的翻译质量总体优秀，准确传达了原文的经济学和数学内容，专业术语翻译规范一致，格式和MyST语法均完整保留，未发现破坏构建的语法错误。存在少量可改进之处：个别内联指令与中文文本间的空格缺失、个别专业术语首次出现时未标注英文原文、以及 rational_expectations.md 中新增了源文档未包含的字体配置代码。这些问题均为轻微问题，不影响整体翻译质量和可读性。 对核心数学术语（里卡蒂方程、哈密顿矩阵、协态、闭环矩阵等）的翻译准确且前后一致，很好地遵循了术语表规范 长难句的拆分和重组符合中文表达习惯，保持了学术文本的严谨性和可读性 数学公式、代码块、交叉引用（{eq}、{prf:ref}、{doc}等）均完整保留，未出现破坏性修改 专有名词如'托宾的 q'、'卡尔曼'、'马尔可夫过程'等翻译准确且符合经济学术语规范 新增的 YAML frontmatter translation 元数据结构正确，符合既定格式要求

Suggestions:

• [minor · fluency] lectures/lq_mean_field_games.md — 概览 (Overview) section, note block: 在 note 块中，译文 '我们对线性调节器所了解的一切都可以用于均衡分析' 稍微偏离英文 'Everything we know about the linear regulator can therefore be brought to bear on the equilibrium: existence conditions, uniqueness, comparative statics, and numerical methods.' 后半句列举内容（存在性条件、唯一性等）已在后文中体现，整体意思准确，但原文强调'可以被用来处理均衡问题的方方面面'，译文的动词选择略显单薄。 → 可考虑译为'因此，我们关于线性调节器所掌握的一切知识都可以运用到均衡分析中：存在性条件、唯一性、比较静态分析和数值方法。'
• [minor · terminology] lectures/lq_mean_field_games.md — ### 存在性和唯一性: 术语 'Loewner ordering' 被译为'洛纳序'，这是一个相对少见的数学术语，建议在首次出现时标注英文原文以便读者查证，例如 '洛纳序（Loewner ordering）'。 → 在洛纳序首次出现处加注英文原名：'在洛纳序（Loewner ordering）中'
• [minor · fluency] lectures/rational_expectations.md — ### 大 Y，小 y 技巧的简单静态示例: '若存在一个由相同企业组成的连续体，每个企业均按照{eq}ree_ex5行事' 一句中，{eq}ree_ex5 前后缺少中文与内联指令之间的空格，不符合语言规范中要求的空格规则。 → 若存在一个由相同企业组成的连续体，每个企业均按照 {eq}ree_ex5 行事
• [minor · formatting] lectures/rational_expectations.md — 让我们从一些标准导入开始: 该代码块中添加了原文没有的字体设置代码（FONTPATH、mpl.font_manager 等），这些是源文档中不存在的内容，属于内容增添。虽然这可能是为了修复中文字体显示问题的工程性调整，但按翻译忠实度原则，不应随意增加源文档未包含的代码逻辑。 → 如非必要，建议与原文保持一致，仅保留 'import matplotlib.pyplot as plt\nimport numpy as np'，字体配置可通过其他全局机制处理。
• [minor · terminology] lectures/lucas_prescott_investment.md — ## 企业与已安装资本的价格: 'Grunfeld' 人名未翻译为中文，而参考术语表中其他经济学家姓名均提供了标准中文译名。虽然 Grunfeld 不在术语表中，但为保持全文人名翻译的一致性，建议补充音译或保留英文并标注。 → 可译为'格伦费尔德（Grunfeld）'，并在首次出现时标注原文。

Summary: The translation sync correctly added two new target files mirroring the two new source files and correctly updated the existing rational_expectations.md target with matching new paragraphs, a new section, updated jupytext/raw-block metadata, and a correctly revised heading-map.

Issues:

• In lq_mean_field_games.md, the heading-map key 'Overview' maps to '概览' but the rendered H2 heading in the body text is '## 概览' - consistent, but note the source English document uses '## Overview' which matches; this is fine.
• Minor: in lucas_prescott_investment.md the translation heading-map omits a mapping for the top-level title duplication check, but 'title' key is present and matches the H1 '# 不确定性下的投资' - no actual issue found.
• In rational_expectations.md, 'Further Reading' (old, capital R) was renamed to 'Further reading' (lowercase r) in the English source; the target correctly updated the heading-map key from 'Further Reading' to 'Further reading' and added 'Concluding remarks' - this was handled correctly.
