Forward Resync: ak2.md

Source: QuantEcon/lecture-python.mystlectures/ak2.md
Source commit: a1cd90c
This PR resyncs the translation to match the current source document.

Reason: The target adds a font configuration block in the implementation code cell (importing matplotlib as mpl, setting FONTPATH to a Chinese font, adding font manager configuration, and setting plt.rcParams for font family) that does not exist in the source. This is beyond typical i18n font setup since it involves specific additional lines not present in source's import block. All other content appears faithfully translated with equivalent structure, formulas, and code logic.

Changes

Whole-file resync applied. The entire document was resynced in a single pass.

✅ Translation Quality Review

Verdict: PASS | Model: claude-sonnet-5 | Date: 2026-07-19


📝 Translation Quality

Criterion Score
Accuracy 9/10
Fluency 8/10
Terminology 9/10
Formatting 9/10
Overall 8.8/10

Summary: This is a high-quality, comprehensive translation that accurately conveys complex OLG model concepts, preserves all mathematical notation and code structure, and maintains consistent terminology aligned with the glossary. Minor concerns include a small interpretive addition in the equilibrium definition and an unexplained font-loading code addition, but these do not significantly detract from the overall excellent quality of the translation. Accurate rendering of complex mathematical and economic terminology (e.g., 拉格朗日函数, 跨期预算约束, 一次性税) consistent with the glossary Equations and LaTeX are fully preserved with correct eq-label syntax Code blocks are fully preserved with appropriately translated comments, maintaining code functionality Natural and fluent academic Chinese register throughout complex derivations and policy experiment descriptions Section headings and cross-references (e.g., {ref}exp-tax-cut) are consistently and correctly mapped via the translation metadata

Suggestions:

  • Definition section '均衡' translation adds '三元组' (triple) which is an interpretive addition not in the English source ('An equilibrium is an allocation, a government policy, and a price system'); consider translating more literally as '一个配置、一个政府政策和一个价格体系' to avoid introducing terminology not in the original
  • In '## 生产' section, 'K_0$ 和 $D_0$ 都以时点 $0$ 的商品单位计量' is accurate but minor - overall this section reads well
  • The added matplotlib font-loading code block (FONTPATH, mpl.font_manager, etc.) in the '实现' section is not present in the English source; while this is likely a necessary localization for CJK font rendering, it should be verified as an intentional/approved addition to avoid flagging as an unauthorized content change
  • In 'Individuals' problems' section, note that C_{ot+1} was silently corrected to C_{o,t+1} throughout the translation (adding a comma for subscript clarity) which deviates from the source formatting, though this appears to be a beneficial consistency fix rather than an error

🔍 Diff Quality

Summary: The target document correctly mirrors the source's structure and content, with the translation metadata frontmatter properly added and headings appropriately mapped.
