Geant 4提供了一组模型来模拟量热计中的强子簇射。最近改进的几个模型有关的强子簇射的建模进行了讨论。这些措施包括改进的横截面，FTF模型的修订，除了准弹性散射的QGS模型，并在核precompound和去激发模型的增强。对薄靶实验的物理模型的验证已经扩展，特别是在能量区域10 GeV及以下。显示了新验证结果的示例。
Geant4 offers a set of models to simulate hadronic showers in calorimeters. Recent improvements to several models relevant to the modelling of hadronic showers are discussed. These include improved cross sections, a revision of the FTF model, the addition of quasi-elastic scattering to the QGS model, and enhancements in the nuclear precompound and de-excitation models. The validation of physics models against thin target experiments has been extended especially in the energy region 10 GeV and below. Examples of new validation results are shown.
