活动区日冕环核心辐射测量（EM）的温度依赖性是加热过程的重要诊断指标。观测结果表明，EM(T)与T-a相似，在约4MK以下，2 < a < 5。利用纳米耀斑序列的零维流体动力学模拟，证明了a与单个纳米耀斑之间的时间（T-N）和纳米耀斑能量分布的关系。如果TN大于几千秒，a
The temperature dependence of the emission measure (EM) in the core of active regions coronal loops is an important diagnostic of heating processes. Observations indicate that EM(T) similar to T-a below approximately 4MK, with 2 < a < 5. Zero-dimensional hydrodynamic simulations of nanoflare trains are used to demonstrate the dependence of a on the time between individual nanoflares (T-N) and the distribution of nanoflare energies. If TN is greater than a few thousand seconds, a
