Summary: The translation of the changed sections is accurate, fluent, and terminologically consistent, with proper preservation of mathematical formatting and code blocks. Only minor issues were found: one inconsistent translation of 'nature' as '本质' instead of '自然' in a plot title, and an unexplained addition of font-configuration code not present in the English source, which should be verified as intentional shared infrastructure rather than a translation artifact. Mathematical notation and LaTeX equations are preserved accurately throughout all modified sections Technical terminology (e.g., 似然比, 库尔贝克-莱布勒散度, 第一类/第二类错误, 检测概率, 虚警概率) is applied consistently and matches standard usage Complex statistical/probabilistic explanations (e.g., KL divergence link to likelihood ratios, Chernoff entropy, ROC curves) are translated clearly and read naturally in academic Chinese

Suggestions:

• [minor · formatting] lectures/likelihood_ratio_process.md — Overview - Python import cell: The translation adds extra code (font configuration lines: FONTPATH, mpl.font_manager.fontManager.addfont, plt.rcParams) that does not exist in the English source code cell. This changes the technical content of a code block beyond translation, which is outside the scope of pure translation and could cause a mismatch with the source if the font file is not actually present in the build environmen… → Remove the added font-configuration lines or confirm they are part of an approved shared build config for all translated lectures; if so, this is not a translation quality issue but should be verified separately.
• [minor · terminology] lectures/likelihood_ratio_process.md — ### Simulations - plot title '马尔可夫链似然比(本质 = f)': The plot title translates 'nature = f' as '本质 = f', but elsewhere in the document '自然' is consistently used to translate 'nature' (as the entity making draws). '本质' means 'essence/nature (character)', which is a mistranslation in this context and inconsistent with the rest of the document. → 改为 '马尔可夫链似然比（自然 = f）'
• [minor · formatting] lectures/likelihood_ratio_process.md — ### A third distribution $h$ (llr_h anchor, listed in Overview heading map as 'Likelihood ratio test::A third distribution $h$'): In the PR's stated list of modified sections, '### A helpful formula' is listed as changed, but the heading mapping in front matter groups it as a subsection under 'Likelihood ratio test' rather than reflecting that this subsection may have been reorganized; this is a minor structural note rather than a translation defect, but worth flagging since the surrounding heading id path could affect cros… → Verify the heading path mapping for '### A helpful formula' and '### A third distribution $h$' matches the actual document structure used by the sync tool.

Summary: The translation sync correctly applied all RNG refactoring changes (adding rng = np.random.default_rng() and threading rng through function signatures) to the Chinese document while preserving translated prose, frontmatter, and structure.

Pull request overview

This automated translation-sync PR updates the Chinese lecture likelihood_ratio_process.md to align with upstream changes that migrate randomness from legacy np.random.* calls to the NumPy Generator API (via a shared rng = np.random.default_rng()), plus updates the translation sync state metadata.

Changes:

• Introduces a shared rng and threads it through multiple simulation functions (Beta draws, uniform draws, choices) to replace legacy global RNG usage.
• Updates call sites throughout the lecture to pass rng into the updated function signatures.
• Updates .translate/state/likelihood_ratio_process.md.yml to reflect the new source commit SHA, sync date, mode, and tool version.

File	Description
lectures/likelihood_ratio_process.md	Replaces np.random.* with rng.* and updates function signatures/call sites accordingly.
.translate/state/likelihood_ratio_process.md.yml	Updates translation-sync state metadata (source SHA, date, mode, tool version).
