本文用透射电子束谱仪研究了聚乙烯、聚苯乙烯和蒸发碳薄膜（约150 nm）中电子能量损失的角分布。结果表明，广泛的能量损失约20 eV，这是共同的三种材料的研究，可以解释在非弹性碰撞的束电子与束缚电子的价态和产生等离子体振荡。
A transmission electron beam spectrometer has been constructed with which the angular distributions of electron energy losses in thin films ( approximately 150 nm) of polyethylene, polystyrene and evaporated carbon ( approximately 50 nm) have been studied. The results indicate that the broad energy loss around 20 eV, which is common to the three materials studied, may be explained in terms of inelastic collisions of beam electrons with the bound electrons of the valence state and generation of plasma oscillations.
