Summary: 翻译整体质量较高，准确传达了原文的经济学和数学概念，专业术语翻译规范。主要问题集中在模拟部分的代码注释和图表标签中存在中英文混杂及'agent'翻译不一致（个体/代理）的现象，属于风格统一性问题而非准确性错误。未发现严重的语法错误或数学公式损坏。 数学公式和代码块完整保留，未出现语法错误 专业术语（如似然比、贝叶斯更新、帕累托权重等）翻译准确，符合术语表 长句结构处理得当，保持了学术文本的严谨性和可读性 标题翻译与YAML frontmatter中的映射保持一致

Suggestions:

• [minor · formatting] lectures/likelihood_ratio_process_2.md — Simulations section, plotting code comments: 在'模拟'部分的代码注释和图例标签中，部分内容被翻译（如'中位数'、'时间'、'代理1的份额'），但同一图表中的其他标签（如'Nature = f'等标题、'Density'、'Overlap'）未翻译，导致中英文混杂，风格不统一。 → 统一翻译或统一保留英文原文，例如将'Nature = f'等标题也翻译为'自然 = f'，并翻译'Density'为'密度'、'Overlap'为'重叠区域'。
• [minor · terminology] lectures/likelihood_ratio_process_2.md — Simulations section, code block plotting agent labels: 术语不一致：正文中'agent'统一译为'个体'（如'个体1'、'个体2'），但在部分代码注释和图例标签中译为'代理'（如'代理1的份额'、'代理1消费份额'），造成术语不统一。 → 统一将'agent'译为'个体'，或在整篇文档中统一使用'代理'，避免混用。
• [minor · formatting] lectures/likelihood_ratio_process_2.md — Overview section code import block: 翻译文档在导入代码块中添加了英文源文档中没有的字体设置代码（FONTPATH、mpl.font_manager等），这虽然是为了支持中文字体渲染而添加的合理修改，但与英文源文档存在结构性差异，建议在评估中确认这是否属于翻译系统的既定惯例。 → 如果这是标准翻译流程的一部分，则无需更改；否则应说明添加原因。
• [nit · fluency] lectures/likelihood_ratio_process_2.md — 在如下不等式的证明中来自 lr_ex4 exercise, '概率模型'段落: 部分长句的翻译稍显生硬，例如'我们想要推导分配$c^i(s^t), i = 1,2$，并观察当以下情况发生时会发生什么'，读起来略显直译腔调，可以更符合中文表达习惯。 → 可改为'我们想要推导出分配 $c^i(s^t), i = 1,2$，并观察在以下情况下会发生什么'。

Summary: The RNG refactoring (adding np.random.default_rng() and replacing np.random.beta/rand calls with rng.beta/rng.random) was correctly and completely mirrored in all corresponding code cells of the Chinese translation.

Pull request overview

This automated translation-sync PR updates the Chinese lecture likelihood_ratio_process_2.md to use NumPy’s Generator API (np.random.default_rng() + rng.*) instead of the legacy np.random.* functions, keeping the zh-cn content aligned with upstream changes.

Changes:

• Introduces rng = np.random.default_rng() and replaces np.random.beta/rand calls with rng.beta/random.
• Updates a simulation helper to draw randomness via the passed generator.
• Updates translation-sync state metadata (source-sha, sync date, mode, tool version).
