提出了一种对静电发射进行分类的方案，并建立了理论模型。所有的发射似乎都是由相同的基本机制产生的：由冷电子（小于100 eV）和热损失锥电子（约1 keV）组成的不稳定电子等离子体分布。每个排放类别都与特定的模型参数范围相关联；因此，宽带电场数据可以用来推断冷等离子体成分的密度和温度。该模型预测等离子体频率附近的陀螺谐波发射需要较大的冷等离子体密度。
A scheme was constructed and a theoretical model was developed to classify electrostatic emissions. All of the emissions appear to be generated by the same basic mechanism: an unstable electron plasma distribution consisting of cold electrons (less than 100 eV) and hot loss cone electrons (about 1 keV). Each emission class is associated with a particular range of model parameters; the wide band electric field data can thus be used to infer the density and temperature of the cold plasma component. The model predicts that gyroharmonic emissions near the plasma frequency require large cold plasma densities.
