大多数大型太阳耀斑表现出通常是脉冲的硬 X 射线发射，以及渐进的热软 X 射线发射。提出了太阳耀斑的光束驱动色球蒸发模型来解释软X射线发射耀斑等离子体的起源。对所讨论问题的仔细评估揭示了理论色球蒸发模型的预测与一组大型 X 型和 M 型耀斑的实际观测之间的矛盾。结果表明，虽然软 X 射线和硬 X 射线发射是同一耀斑的结果，但其中一个不是另一个的结果。
Most large solar flares exhibit hard X-ray emission which is usually impulsive, as well as thermal soft X-ray emission, which is gradual. The beam-driven chromospheric evaporation model of solar flares was proposed to explain the origin of the soft X-ray emitting flare plasma. A careful evaluation of the issue under discussion reveals contradictions between predictions from the theoretical chromospheric evaporation model and actual observations from a set of large X- and M-type flares. It is shown that although the soft X-ray and hard X-ray emissions are a result of the same flare, one is not a result of the other.
