Summary: 整体翻译质量很高，准确传达了原文的经济学和数学内容，专业术语翻译规范且与术语表高度一致，MyST格式（数学公式、证明环境、代码块、交叉引用）均完整保留且未发现语法错误。仅存在少量可改进之处，如部分长句翻译稍显生硬、以及个别代码注释的翻译风格与其他章节不完全一致，但均属于轻微问题，不影响读者理解。 对里卡蒂方程、哈密顿结构、协态系统等高度专业化的数学术语翻译准确一致，符合术语表要求 长篇幅的数学推导、证明步骤与代码注释保持了与原文完全对应的结构和编号，公式引用无误 经济学专业术语（如托宾q、消费者剩余、竞争均衡、理性预期）翻译准确且与术语表保持一致 译文在复杂从句和被动语态处理上总体流畅自然，符合学术文本的中文表达习惯 Suggestions:

Copilot review overview
🟡 Changes recommended
There is at least one confirmed typo in the updated lecture text and the ToC captions were changed to English across the zh-cn navigation, which is a user-visible language inconsistency.

What changed in this PR
This PR syncs new/updated lecture translations from QuantEcon/lecture-python.myst into the zh-cn lecture set, adding two sequel lectures related to the rational expectations content and updating navigation and references accordingly.
Changes:
- Added two new translated lectures:
lucas_prescott_investmentandlq_mean_field_games - Updated
rational_expectationsto reference the sequel lectures and added a concluding remarks section - Updated the book ToC and bibliography to include the new lectures and citation entries, plus translation state metadata updates

QuantEcon/lecture-python.myst#1070 added two lectures, but this PR delivered only lucas_prescott_investment: optimal_growth_uncertainty failed the structural parity check (the model dropped the leading {raw} header block and the anchor), so its sync failure was filed as QuantEcon/lecture-python.myst#1072 and the file never arrived. This PR's _toc.yml and lucas_prescott_investment both point at it, so the preview could not build. translate init -f optimal_growth_uncertainty.md at engine v0.29.6 (@v0), claude-sonnet-5, from lecture-python.myst main (9ad04de; the file's last change is 0abf403, the #1070 merge). Parity passed on the first attempt. Output as written by the CLI. Its font path, font block placement, two English figure captions and one term are repaired in the next commit. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Hand repairs to the seed in the previous commit: - The engine writes FONTPATH as _fonts/...; this edition keeps the font in lectures/fonts/ (110 of the other 111 lectures), so the build would fail with FileNotFoundError. Path corrected, and the i18n block moved from the first plotting cell into the imports cell, where the rest of the edition keeps it. - Both figure captions (cell metadata) came through in English, the QuantEcon/action-translation#255 class: localised to "运动规律与托宾 q" and "不变分布以及投资与 q 的关系". - "law of motion" was rendered 运动法则 (axis title and one sentence); the edition uses 运动规律 throughout (107 occurrences), so aligned. Verified against the English source: identical directive sequence (43), anchors, the 51 cross-references and citations, heading levels, and code cells (ASTs with string literals masked); every display-math block identical except \text{with probability one} -> \text{以概率1成立}, the edition's practice. All 13 code cells execute from lectures/ with numerical output identical to the English, and both figures render in Source Han Serif SC with no missing-glyph warnings. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
This sync wrote the source _toc.yml whole, which turned all 19 part captions back to English (the QuantEcon/action-translation#254 class, fixed in the engine on 2026-10-09, after this PR was opened). Rebuilt from main's _toc.yml plus only this PR's three lectures, at their source positions: lucas_prescott_investment and optimal_growth_uncertainty after rational_expectations, and lq_mean_field_games after two_computation. Every entry resolves to a file on this branch. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
lucas_prescott_investment (5) and lq_mean_field_games (4) arrived with their mystnb figure captions in English, the QuantEcon/action-translation#255 class. Each caption now uses the term its lecture's own text uses (需求序列独立 for IID demand, 遍历集, 过渡路径, 总量状态, 商店). Plot labels in both lectures are English and need no font block; that is the edition-wide QuantEcon/action-translation#178 class and is left as is.

Repaired on the branch (2026-10-22); the PR now delivers all of QuantEcon/lecture-python.myst#1070 and builds. Part of #298.
Checks. All four lectures match their English source structurally (directive sequence, anchors, cross-references and citations, headings, code cells compared with string literals masked). Executed locally from For the reviewer: "Tobin's q" appears as both 托宾 q and 托宾的 Merge order: this PR first, then #294, then #296. Their fixes are staged and go up after this merges, since every later merge moves |

QuantEcon/lecture-python.myst#1087 added gallant_tauchen; its sync PR, #294, could not build until #286 landed. When #286 merged, the rebase automation re-translated the lecture at @v0 (v0.29.6) and force-pushed the branch, and GitHub shut that PR in the same second (the QuantEcon/action-translation#280 race). The lecture and its state file are taken unchanged from that branch (5d35ce7). Checked against the English source: identical directive sequence (43), math blocks, anchors, the 54 cross-references and citations, headings and code cells; all 23 code cells execute with numerical output identical to the English.

…closed #294 and #296) (#300) * Add gallant_tauchen, as the sync's rebase delivered it at v0.29.6 QuantEcon/lecture-python.myst#1087 added gallant_tauchen; its sync PR, #294, could not build until #286 landed. When #286 merged, the rebase automation re-translated the lecture at @v0 (v0.29.6) and force-pushed the branch, and GitHub shut that PR in the same second (the QuantEcon/action-translation#280 race). The lecture and its state file are taken unchanged from that branch (5d35ce7). Checked against the English source: identical directive sequence (43), math blocks, anchors, the 54 cross-references and citations, headings and code cells; all 23 code cells execute with numerical output identical to the English. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * gallant_tauchen: localise the two English figure captions Both mystnb figure captions arrived in English, the QuantEcon/action-translation#255 class. Each uses the lecture's own terms: 公共随机数 and 重新抽取扰动项 (the two curves' descriptions in the text above the figure), 准则函数, 随机波动率 and 收益率. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Seed social_security_depletion, the lecture its sync could not deliver QuantEcon/lecture-python.myst#1091 added social_security_depletion, but its sync failed the structural parity check (the model dropped the leading {raw} header block), filed as QuantEcon/lecture-python.myst#1092, so its sync PR (#296) opened with a _toc.yml change and no lecture. translate init -f social_security_depletion.md at engine v0.29.6 (@v0), claude-sonnet-5, from lecture-python.myst main (9ad04de; the file's last change is 97c5894). The first attempt failed parity the same way and wrote nothing; the second passed. Output as written by the CLI. Its font path is repaired in the next commit. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * social_security_depletion: font path The engine writes FONTPATH as _fonts/...; this edition keeps the font in lectures/fonts/, so the build would fail with FileNotFoundError. The block is already in the imports cell, and nothing after it resets font.family. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * bib: add the 21 entries the two lectures cite gallant_tauchen cites 17 keys and social_security_depletion 4 that this edition's bibliography lacks. Each is copied verbatim from the source bib and placed after the nearest preceding entry the two files share, keeping the source's order. Additions only; the same 21 keys the sync's rebase added on the two closed PRs' branches. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * _toc.yml: add gallant_tauchen and social_security_depletion At their source positions: gallant_tauchen after market_diffusion, and social_security_depletion after two_computation, before lq_mean_field_games. Built on main's _toc.yml, so the Chinese part captions are untouched. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * gallant_tauchen state: record the file's last source commit The sync recorded source-sha as f8d7e33, the merge commit of QuantEcon/lecture-python.myst#1087, which was a true merge rather than a squash. translate status compares source-sha with the file's last commit, 648d138 (the PR's head), so it reported this lecture OUTDATED although the source blob is identical at both. Recorded as 648d138, the convention translate init and the other 138 state files in this edition follow; nothing else in the file changes.
