## Translation Guidelines

- Translate faithfully, not literally — preserve scientific meaning
- Keep all numbers, chemical formulas, gene names, and proper nouns in original form
- For ambiguous terms, provide both: "催化活性（catalytic activity）"
- Technical terms: use standard Chinese scientific terminology
  - e.g., "oxygen evolution reaction" → "析氧反应（OER）"
  - "density functional theory" → "密度泛函理论（DFT）"
- Preserve hedging language: "suggest" → "表明", "indicate" → "指出", "demonstrate" → "证明"

## Figure Grounding Rules

For each figure mentioned in the text:
1. Find the corresponding figure caption
2. Note which result/claim the figure supports
3. Note the key quantitative message of each panel
4. Flag any discrepancy between text claims and figure data
