### 电子
由于该模型较为简单，使用`Geant4`的`General Particle Source`（`GPS`）可以较为方便地生成源，

### 质子与俘获辐射
由于模型较为复杂，且需要发射的粒子种类繁多，因此该部分的粒子使用`G4ParticleGun`生成，关键是生成各向同性（在球面上均匀分布）的位置、方向和符合能谱的能量分布。
由于模型较为复杂，且需要发射的粒子种类繁多，因此使用`G4ParticleGun`生成各类粒子，关键是生成各向同性（在球面上均匀分布）的位置、方向和符合能谱的能量分布。
1. `Inverse Transform Method`（`ITM`）
对于一个在$[a, b]$的分布，设其概率密度函数(PDF)为$F(x)$，对其积分可获得累积分布函数(CDF)，记为$y=C(x)=\int_a^x F(u)\mathrm{d}u$，其反函数为$C^{-1}(y)$。设$y$为$[0, 1)$上均匀分布的随机数，则$x=C^{-1}(y)$满足$F(x)$的分布。

为了保证发射方向是朝向球面内，因此需要限制$\theta$的最大角度为$90^{\circ}$。
