-### 6.3 扩散模型设计 — 高斯烟团模型（Gaussian Puff）
+### 6.2.1 系统内置默认值（第三方提供前使用）
+
+基于 155mm 炮弹载荷的物理合理估计：
+
+| 参数 | 惰性气体弹 | 活性材料弹 | 活性燃料弹 |
+|------|------|------|------|
+| 药剂质量 (SourceStrength) | 10 kg | 12 kg | 10 kg |
+| 爆发药 TNT 当量 (BurstChargeKg) | 1.5 kg | 4.0 kg | 1.5 kg |
+| 有效浓度阈值 (EffectiveConcentration) | 0.0001 kg/m³ | 0.0002 kg/m³ | 0.0001 kg/m³ |
+| 湍流扩散系数 (TurbulentExpansionK) | 3.0 | 4.0 | 3.0 |
+| 最大半径 (MaxRadius) | 100 m | 80 m | 90 m |
+| 最大持续时间 (MaxDuration) | 120 s | 90 s | 100 s |
+| Phase 1 初始半径 (R₀) | 3.75 m | 5.14 m | 3.75 m |
+
+> **数据来源**：10kg烟幕剂，抛射药/烟幕剂质量比 5%-20%，TNT当量取 1.5kg（典型值）。活性材料弹取爆炸分散型上限 4kg。
+
+### 6.3 扩散模型设计 — 高斯烟团模型（Gaussian Puff）V2
#### 6.3.1 模型选择
-选用**高斯烟团扩散模型**（Gaussian Puff Model），理由：
-- 计算简单，适合实时 20Hz Tick
-- 能反映风速、大气稳定度对扩散的影响
-- 工业级大气扩散的经典方法
+采用**高斯烟团扩散模型**，使用**Pasquill-Gifford 稳定度分类**计算扩散系数 σ。
-#### 6.3.2 核心公式
+#### 6.3.2 大气稳定度映射
+
+从天气类型和风速推导稳定度等级，无需额外参数：
+
+| 天气 | 风速 | 稳定度 | 太阳辐射 | 湍流 |
+|------|------|------|------|------|
+| 晴天 | ≤ 5 m/s | A（极不稳定） | 强 | 强 |
+| 晴天 | > 5 m/s | B（不稳定） | 中 | 中 |
+| 阴天 | 任意 | D（中性） | 弱 | 中 |
+| 雨天 | 任意 | D（中性） | 弱 | 中 |
+| 雾天 | 任意 | E（稳定） | 无 | 弱 |
+| 夜间 | 任意 | F（极稳定） | 无 | 最弱 |
+
+#### 6.3.3 σ 扩散系数（Pasquill-Gifford）
+
+扩散距离 x 米后，水平扩散系数 σ_y、垂直扩散系数 σ_z（单位 m）：
+
+| 稳定度 | σ_y | σ_z |
+|------|------|------|
+| A | 0.22x / (1+0.0001x)^0.5 | 0.20x |
+| B | 0.16x / (1+0.0001x)^0.5 | 0.12x |
+| C | 0.11x / (1+0.0001x)^0.5 | 0.08x / (1+0.0002x)^0.5 |
+| D | 0.08x / (1+0.0001x)^0.5 | 0.06x / (1+0.0015x)^0.5 |
+| E | 0.06x / (1+0.0001x)^0.5 | 0.03x / (1+0.0003x)^0.5 |
+| F | 0.04x / (1+0.0001x)^0.5 | 0.016x / (1+0.0003x)^0.5 |
+
+> 对于瞬时释放的烟团（Puff），扩散距离 x 取云团中心随风漂移的距离：x = u × t，其中 u 为风速，t 为经过时间。若风速为 0，取 x ≈ 1m（纯湍流扩散）。
+
+#### 6.3.4 浓度场公式
云团内任意点 (x, y, z) 在时刻 t 的浓度：
```
-C(x, y, z, t) = ────────────── × exp[ -½( (x-ut)/σx )² ]
- (2π)^(3/2) σx σy σz
-
+C(x, y, z, t) = ────────────── × exp[ -½( (x-ut)/σy )² ]
+ (2π)^(3/2) σy σy σz
× exp[ -½( y/σy )² ]
-
× { exp[ -½( (z-H)/σz )² ] + exp[ -½( (z+H)/σz )² ] }
其中：
- Q = 源强（释放总量）
+ Q = 源强（释放物质总量，kg），来自 AmmunitionSpec
u = 风速（m/s）
H = 有效释放高度（m）
- σx, σy, σz = 三轴扩散系数，随时间增大
+ σy, σz = 扩散系数（由 6.3.2 和 6.3.3 确定）
```
-#### 6.3.3 简化方案
+#### 6.3.5 可判定指标
-完整三维浓度场计算量大。实时仿真中采用**简化方案**：
+| 指标 | 计算 | 说明 |
+|------|------|------|
+| 中心浓度 | C_max = Q / [(2π)^(3/2) σy² σz] | 云团最浓处 |
+| 有效半径 | R_eff = min{ r | C(中心, r) < C_threshold } | 浓度超过阈值的范围 |
+| 消散条件 | C_max < C_threshold / 10 或 经过时间 > MaxDuration | 浓度可忽略 |
-```
-简化假设：
- - 云团近似为球体（σx = σy = σz = σ）
- - 半径 R(t) = InitialRadius + DispersionRate × t
- - DispersionRate = DispersionRateBase × f(风速, 大气稳定度)
- - 中心随风速漂移：Center(t) = Center(0) + WindVector × t
- - 密度随半径衰减：Density(t) = CoreDensity × (InitialRadius / R(t))³
+> **简化**：实时判定时，无人机位于云团内当且仅当 C(无人机坐标) ≥ EffectiveConcentration。不需要球体假设，直接用高斯公式计算。
-简化判定：
- - 无人机进入球体 → 暴露于云团
- - 密度 ≥ EffectiveConcentration → 有效毁伤
- - 半径 ≥ MaxRadius OR 时间 ≥ MaxDuration → 消散
-```
+#### 6.3.6 AmmunitionSpec 调整
-#### 6.3.4 接口
+| 字段 | 变更 | 说明 |
+|------|------|------|
+| `DispersionRateBase` | ❌ 删除 | 由 PG 稳定度代替 |
+| `InitialRadius` | 保留 | 仍作初始 σ 参考 |
+| `SourceStrength` | ✅ 新增 | 源强 Q（kg），取代线性模型 |
+
+> 浓度 C 的单位为 kg/m³，无人机是否受损取决于 C ≥ EffectiveConcentration。
+
+#### 6.3.7 接口（不变）
