Summary: 译文整体质量很高，准确传达了原文关于 Gallant-Tauchen 有效矩方法的技术细节和数学推导，专业术语基本遵循术语表且使用一致，公式、代码块与引用格式完整无误。仅存在个别措辞可以更加地道流畅的空间，以及一两处术语译法可酌情讨论，但均不影响整体理解，不存在实质性准确性或格式问题。数学公式、代码块及标签引用均完整保留，未出现格式或语法错误专业术语如“伪真值”“过度识别约束”“光滑嵌入”等译法准确且前后一致长难句的拆分和重组处理得当，保持了学术文本应有的严谨性和可读性

Suggestions:

[minor · fluency] lectures/gallant_tauchen.md — ## 选择得分生成器: “Gallant 和 Tauchen 告诫不要取过多的项，而后又声称标准渐近理论仍然适用”一句中“而后又声称”与英文原意（警告不要犯这种错误）略有偏差，容易让人理解为先后发生的两个独立动作，而原文是在警告一种常见的错误做法（取过多项之后却仍声称标准渐近理论适用）。 → Gallant 和 Tauchen 告诫道：不要取过多的项，却仍声称标准渐近理论适用。
[minor · terminology] lectures/gallant_tauchen.md — ## 与匹配辅助参数的方法的比较: “binding function”译为“约束函数”虽可理解，但该术语在计量经济学文献中常译为“绑定函数”或保留英文，意译为“约束函数”可能与“constraint function”混淆，建议斟酌统一。 → 可考虑译为“绑定函数”或保留英文标注“binding function（绑定函数）”
[nit · fluency] lectures/gallant_tauchen.md — ## 概述: “经济学家只是作为估计 $\rho$ 的一个步骤”这句稍显生硬，但基本准确，可考虑更口语化的表达以提升流畅度。 → 经济学家估计 $\theta$，仅仅是为了估计 $\rho$ 迈出的一步。

🟡 Changes recommended

_toc.yml adds three entries (lucas_prescott_investment, optimal_growth_uncertainty, lq_mean_field_games) pointing to lecture files that do not exist, which breaks the Jupyter Book build and is outside the PR's stated scope.

What changed in this PR

This is an automated translation-sync PR that ports the English lecture "Which Moments to Match?" (Gallant and Tauchen's efficient method of moments / EMM) from QuantEcon/lecture-python.myst (source PR #1087) into the Chinese book. It adds the translated lecture, registers it in the table of contents, adds the 17 bibliography entries it cites, and records the translation state.

Changes:

Add new translated lecture lectures/gallant_tauchen.md with a translation: front-matter block (title + 15 English→Chinese heading map) and matching state file.
Add 17 new BibTeX entries to quant-econ.bib covering the lecture's citations (keys verified unique, no duplicates).
Update lectures/_toc.yml to list the new lecture — but also adds three unrelated entries for files that do not exist.

File	Description
`lectures/gallant_tauchen.md`	New Chinese translation; cross-refs, equation labels, internal `{ref}` labels, and citation keys all resolve correctly.
`lectures/_toc.yml`	Adds `gallant_tauchen` (valid) plus `lucas_prescott_investment`, `optimal_growth_uncertainty`, `lq_mean_field_games` (missing files, out of scope).
`lectures/_static/quant-econ.bib`	Adds 17 references used by the lecture; keys are unique and `Hansen1982` already exists.
`.translate/state/gallant_tauchen.md.yml`	Translation state metadata; consistent with existing `NEW`-mode state files and matches the PR's source SHA and section count (15).

♻️ Automatically rebased after #286 was merged.

Overlapping files: lectures/_toc.yml

The translation content is preserved; only unchanged sections were updated to match the current main branch. Please re-review if needed.

@v0

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 by GitHub, not by hand: the rebase automation force-pushed this branch when #286 merged (2026-10-21), and the PR closed in the same second (the QuantEcon/action-translation#280 race). The lecture is delivered in #300, on a recover/ branch the automation does not rebase; see its description.

@v0

…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.
