✅ Translation Quality Review

Verdict: PASS | Model: claude-sonnet-5 | Date: 2026-08-02
Routing: editor — 1 minor finding(s) in gating categories (accuracy/terminology/syntax/diff-check/other)


📝 Translation Quality

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

Summary: 翻译整体质量很高,准确传达了原文的经济学与统计学概念,专业术语翻译规范且与术语表保持一致,格式和MyST语法均正确保留。仅存在少量可优化的措辞问题,均为轻微级别,不影响读者理解核心内容。 专业术语(如信念、鞅、贝尔曼方程、似然比过程、布莱克韦尔序等)翻译准确且与术语表保持一致 数学公式、代码块和MyST指令格式完整保留,未出现语法错误 长难句的拆分和重组符合中文表达习惯,术语一致性在两篇文档中保持良好 标点符号规范使用全角中文标点,行内代码与中文文本间的空格处理得当

Suggestions:

  • [minor · accuracy] lectures/market_diffusion.md — ## Concluding remarks: 英文原文中的短语 'The distinctive lesson of {cite:t}BergemannValimaki1997 is that this convexity is shared by competitors' 被翻译为 '独具特色的启示是……',将主语从原文的 'lesson'(启示/教训)转移,句式调整后含义基本保留,但 'distinctive' 修饰的是 lesson 而非直接归于作者,译文 '{cite:t}BergemannValimaki1997 独具特色的启示' 略显生硬,可优化为 '{cite:t}BergemannValimaki1997 得出的独特启示是……' 以更符合中文表达习惯。 → {cite:t}BergemannValimaki1997 得出的独特启示是,这种凸性是竞争对手所共享的。
  • [minor · fluency] lectures/pricing_information.md — ## The seller's problem: '第三部分说明在我们的二元设置中,菜单上的每个实验都有 $\pi_1 = 1$$\pi_2 = 1$。' 中 'Part 3' 译为 '第三部分' 稍显直白,可考虑译为 '命题第3点' 以更贴合上下文中列举的编号形式,但这属于风格性问题,不影响理解。
  • [nit · terminology] lectures/market_diffusion.md — ## Diffusion over time: 'the mean market share $\hat n(t)$ is increasing over time' 翻译为 '平均市场份额 $\hat n(t)$ 随时间递增',准确无误,但与前文 'S形扩散' 命题标题中使用了 'S形' 而非 '英文字母S形',建议统一确认是否需要保留英文字母S的斜体或特殊标记以保持一致性(当前译文体现一致,无需改动,仅作为风格观察记录)。

🔍 Diff Quality

本节中现有两讲聚焦于价值完全出于工具性目的的信息。

在 {doc}`pricing_information` 中,卖方设计并为实验定价,其中有趣的经济学源于布莱克维尔序不完备这一事实。

```{code-cell} ipython3
print('comparing the dynamic equilibrium with the static one, on [0.05, 0.95]')
print(f' max |p2 - p2_myopic| {np.abs(p2(mkt, A_int) - p2(mkt, A_int)).max():.2e}')
