+
+正式 HRR 校正在测试结束后执行。测试期间记录的 `D354 × 1000` 为原始 HRR，原始数据不会被覆盖。
+
+## 标定文件
+
+标定文件路径：
+
+```text
+%LOCALAPPDATA%\ConeCalorimeter\heat-release-response-calibration.json
+```
+
+标定参数必须来自已知热释放输入的燃烧器阶跃或脉冲试验，不得根据某次试样的目标峰值手工调整。
+
+```json
+{
+  "Version": "标定版本",
+  "CalibratedAtUtc": "2026-06-12T00:00:00Z",
+  "Method": "燃烧器阶跃或脉冲标定方法说明",
+  "SampleIntervalSeconds": 1.0,
+  "RegularizationLambda": 0.02,
+  "GradientStep": 0.05,
+  "Iterations": 1500,
+  "ConvergenceTolerance": 0.000001,
+  "MaximumAreaErrorPercent": 0.01,
+  "ValidationErrorPercent": 0.0,
+  "ResponseKernel": [0.0]
+}
+```
+
+`ResponseKernel` 和 `ValidationErrorPercent` 示例值仅表示字段结构，不能直接用于正式检测。必须替换为燃烧器标定及独立验证得到的值；程序会自动归一化响应核。
+
+## 正式结果约束
+
+- 校正 HRR 全程非负。
+- 校正后的最终 THR 严格匹配设备原始最终 THR。
+- 正式最大 HRR 从校正曲线计算。
+- 实时数据页和 Excel 保持原有列结构，测试结束后原有 HRR、THR 和最大热释放字段直接使用校正结果。
+- 原始 HRR、THR 与校正版本仅在程序内部保留，不新增操作员可见列。
+- 缺少有效标定文件或校正失败时，可以导出原始实时数据，但禁止导出正式报表。
