✅ Translation Quality ReviewVerdict: PASS | Model: claude-sonnet-4-6 | Date: 2026-04-13 📝 Translation Quality
Summary: The translation of the modified sections is of high quality overall. The new Sharp Bits section and its subsections (Typing and Global Variables) are accurately and fluently translated. The Base Version and Acceleration via Numba subsections are well-handled. The How and When it Works section and Overview modifications are accurate. Minor considerations include the translation of the section heading 'Sharp Bits' which loses some of its colloquial 'gotcha' nuance, and the 'Typing' heading which is rendered as '类型推断' (Type Inference) rather than the broader '类型问题'. These are minor issues that don't significantly impact comprehension. All formatting, math, and code blocks are preserved correctly. Accurate translation of JIT compilation concepts, correctly rendering 'just-in-time compilation' as '即时编译' throughout The new Sharp Bits section (## 注意事项) and its subsections (### 类型推断, ### 全局变量) are well-structured and accurately convey the technical content about Numba limitations The Added sections 'Base Version' (#### 基础版本) and 'Acceleration via Numba' (#### 通过 Numba 加速) are clearly translated and maintain proper technical terminology Multithreaded Loops section accurately translates parallel computing concepts including 'prange' usage and the explanation of parallelization across households vs. time The admonition block 'Remark' is correctly translated as '备注' and the decorator syntax explanation is accurate Mathematical notation and LaTeX formatting are fully preserved throughout all modified sections The translation of the global variables gotcha explanation is accurate and preserves the warning emoji 😱 Suggestions:

Pull request overview
Automated translation sync for the zh-cn Numba lecture, aligning lectures/numba.md (and its translation state metadata) with the latest upstream edits from QuantEcon’s English source.
Changes:
- Updated translation frontmatter headings and internal anchors to match upstream structure.
- Refreshed several narrative/code sections (Numba intro, JIT usage examples, multithreading section) per upstream edits.
- Updated translation sync state (
source-sha,synced-at, tool version, etc.).

qm的for循环体缩进不正确:for t in range(n):下一行只有 2 个空格缩进,无法与外层缩进层级匹配,会导致 Python 抛出IndentationError(或使循环体不在预期作用域内)。请将循环体缩进对齐到函数内的标准缩进层级。
def qm(x0, n, α=4.0):
x = np.empty(n+1)
x[0] = x0
for t in range(n):
x[t+1] = α * x[t] * (1 - x[t])
return x

| 当 Numba *无法* 推断所有类型信息时,它将抛出错误。 | ||

| 以下是 `qm` 的写法 | ||
| 例如,在以下情况中,Numba 在编译 `iterate` 时无法确定函数 `g` 的类型: | ||
|
|

| ```{code-cell} ipython3 | ||
| @jit | ||
| def qm(x0, n): | ||
| x = np.empty(n+1) | ||
| x[0] = x0 | ||
| def iterate(f, x0, n): | ||
| x = x0 | ||
| for t in range(n): | ||
| x[t+1] = α * x[t] * (1 - x[t]) | ||
| x = f(x) |

这里用 @jit 来演示“无法推断类型会抛错”不够可靠:jit 默认允许回退到 object mode,iterate(g, ...) 可能不会抛出错误,从而与上文叙述/注释(“This code throws an error”)不一致。若目标是稳定地产生类型推断失败的错误,请使用 @njit 或显式设置 nopython=True。
