能够确定耀斑等离子体电离平衡状态的诊断对于确定耀斑的物理条件是重要的。在空军卫星P78-1上进行的一项实验提供了高分辨率的X射线谱，使人们有可能确定日冕耀斑等离子体的电离平衡状态。所考虑的调查的目的是表明，钙结果的解释是复杂的几个可能的混合线q，并指出在观察到的比例，这似乎很难解释的变化。可能的解释的意见进行了讨论，考虑到电离平衡计算的可能性，必须加以改进。另一种可能的解释与乌尔诺夫（1981）和卡列夫等人（1980）提出的关于高能非热电子产生的效应的建议有关。
A diagnostic capable of determining the state of ionization equilibrium in flare plasmas is important for the determination of the physical conditions in flares. An experiment on the Air Force satellite P78-1 has provided high-resolution X-ray spectra which make it possible to determine the state of the ionization equilibrium in coronal flare plasmas. The considered investigation has the objective to show that the interpretation of the calcium results is complicated by several possible blends to line q, and to point out a variation in the observed ratios which seems difficult to account for. Possible explanations for the observations are discussed, taking into account the possibility that the ionization equilibrium calculations have to be improved. Another possible explanation is related to a suggestion made by Urnov (1981) and Karev et al. (1980) concerning the effects produced by the presence of high-energy nonthermal electrons.
