在本文中，我们报告的改进实施宇宙学辐射传输代码崩溃。特别是，我们提出了一种新的多频算法的光谱采样，它利用彩色光子包：我们讨论了需要的多频方法，描述其实现和提出改进的碰撞性能再现电离辐射的影响与任意频谱。我们进一步讨论了代码实现中的微小变化，这些变化允许更有效的性能和更高的精度。
In this paper, we report on the improvements implemented in the cosmological radiative transfer code crash. In particular, we present a new multi-frequency algorithm for spectra sampling which makes use of coloured photon packets: we discuss the need for the multi-frequency approach, describe its implementation and present the improved crash performance in reproducing the effects of ionizing radiation with an arbitrary spectrum. We further discuss minor changes in the code implementation which allow for more efficient performance and an increased precision.
