我们提出了一个模块化的和高度通用的测试粒子辐射流体动力学代码，同时模拟粒子束能量传输和沉积，相应的爆炸响应的耀斑大气和NLTE（NLTE，等离子体和辐射的局部热力学平衡）辐射传输部分电离氢在色球和光球。计算区域包括光球层、色球层、过渡区和初始流体静力学耀斑前大气的日冕。为了证明潜在的代码，我们计算的时间演变的巴耳末线轮廓对应的时间变化的电子束通量来自观测到的耀斑硬X射线发射。
We present a modular and highly versatile test particle-radiative hydrodynamic code which simultaneously models the particle beam energy transport and deposition, the corresponding explosive response of the flare atmosphere and the NLTE (NLTE, plasma and radiation out of the local thermodynamic equilibrium) radiative transfer for partly ionized hydrogen in the chromosphere and photosphere. The computational domain covers the photosphere, the chromosphere, the transition region, and the corona with the initial hydrostatic preflare atmosphere. To demonstrate the potential of the code, we calculate the time evolution of the Balmer line profiles corresponding to the time variation of the electron beam flux derived from the observed flare hard X-ray emission.
