## 当前翻译状态2026-06-08
### Phase 3 验证硬性标准
创建 `.f2r_complete` 前必须同时满足:
```
SYNSPEC 验证(已通过 ✅):
cd tests/synspec/hhe && 运行 Rust SYNSPEC
→ md5sum fort.7 必须与 Fortran 参考 fort.7 一致
TLUSTY 验证(当前未通过):
cd tests/tlusty/hhe_rust && 运行 Rust TLUSTY
→ md5sum fort.7 必须与 tests/tlusty/hhe_fortran/fort.7.ref 一致
→ 或逐行数值偏差 < 1%DM, T, Ne, Rho 四列全部
如果不满足 → 不能标记 phase=done不能创建 .f2r_complete
```

# TLUSTY 运行验证
cd tests/tlusty/hhe_rust
rm -f fort.7 rust.6 stderr.txt
# 先确保有 fort.8 模型文件(如果需要)
cp ../hhe/fort.8 . 2>/dev/null

../../../target/debug/synspec < hhe35nl.5 > rust.6 2>stderr.txt
# 检查fort.7 是否生成且非空?
ls -la fort.7
cat stderr.txt
```
**判定标准:**
- ✅ `fort.7` 生成且非空 → 任务完成
- ❌ panic / 无输出 / `fort.7` 为空 → **必须修复**,不能标记 ✅
## ★ 自修正机制
每次运行后,根据实际错误更新本文件和 `.f2r_tasks`
```
1. 运行程序 → 观察错误panic 信息、空输出、stderr
2. 定位 bug 位置(文件名:行号)
3. 修复 bug → 编译 → 重新运行
4. 如果发现新的运行问题:
a. 添加到 .f2r_tasks
b. 更新 phase2-integrate.md 中的已知问题
5. 只有实际运行通过才能标记 ✅
```

### 最新验证 (2026-06-05, session #16) — 温度导数改进
**NITER=0 pass-through**: MD5=`57e3fb8adf341397ebcd4abf5be63ac5` — 字节一致 ✅
**Rust NLTE (NITER=10, SOLVES=1)**: chmx ~0.23% (iter=10 lfin=true) — **4x改善**
- SOLVES chmx: iter2=0.173% → iter3-6≈0.14% → iter7=0.38% → iter8-10≈0.23%
- 修复: 有限差分温度导数现在包含自洽 ne + Saha 种群扰动
- 之前 (session #15): chmx 0.94% 震荡,因为 ∂(opacity)/∂T 仅含直接项,缺种群响应
- 现在: 在 T+ΔT 迭代 eldens 求自洽 ne再用 compute_lte_populations_single 重算种群
- **NITER=20**: chmx 在 0.14-0.78% 间周期性震荡 (Kantorovich 累积效应)
- Build: cargo build 通过 (616 warnings)
### 最新验证 (2026-06-11, session #17) — 灰大气深度网格修复
**灰大气模型**: 不再用常数 κ=0.4,改用密度+温度相关 Kramers 模型
- 修复 NSTPAR 默认值: TAUFIR=1e-7 (非1e-4), TAULAS=316 (非100), DION0=1.0 (非0.5)
- κ = κ_es + 4.3e24 * ρ * T^(-3.5) (匹配 Fortran ROSSOP 行为)
- 预测-校正法积分流体静力学平衡(对应 Fortran LTEGR lines 130-182
**Rust NITER=30**: MD5=`4caa3baa6bf4eee367f4f32dca50acce`31次迭代收敛
- 深度网格: DM 偏差 -42% ~ +29%(之前常数 κ: -99.9% ~ +45%
- 温度: 偏差 -6.6% ~ +7.9%(之前: -91% ~ -41%
- 深层温度: id=70 仅差 0.3% (137872 vs 137404)
- 表面温度: id=1 差 8% (26306 vs 28392),因简化 κ 模型

## 已知差距(按优先级排序)
1. **不透明度温度导数 (部分解决)**: 自洽 ne+Saha 有限差分已改善 4x (0.94%→0.23%)。进一步改善需要:
1. **灰大气深度网格 (session #17 部分解决)**: Kramers κ(ρ,T) 模型给出 DM 偏差 <42%T 偏差 <8%。进一步改善需要:
- 连接 ROSSOP → MEANOPT → OPCTAB 完整不透明度链
- 连接 ELDENS (精确 ne) → WMM (精确平均分子量)
- 预计需要 1-2 天完整实现
2. **不透明度温度导数 (部分解决)**: 自洽 ne+Saha 有限差分已改善 4x (0.94%→0.23%)。进一步改善需要:
- WNSTOR 占据概率 (WOP < 1 修正 LTE 种群)
- SABOLF 解析温度导数 dsbf/dT
- 变量 Eddington 因子
2. **Lucy 流体静力学**: ihecor=1 时密度积分产生浮点溢出 → 不透明度→0 → Jν→0。需要修复 BOLK/dm 除法
3. **INITIA 完整实现**: 当前使用 fort.8 读入模型,非自洽灰大气创建
4. **INIFRC 集成**: 翻译完整但未在 INITIA 中调用
- 变量 Eddinger 因子
3. **Lucy 流体静力学**: ihecor=1 时密度积分产生浮点溢出 → 不透明度→0 → Jν→0。需要修复 BOLK/dm 除法
4. **INITIA 完整实现**: 当前使用简化版灰大气创建,需要完整 INITIA含 NSTPAR namelist 解析)
