本文从理论上研究了表面态电子在液态氦上的高场输运。利用玻尔兹曼输运方程求解了电子分布函数的显式形式，其中电子-瑞波子和电子-氦气体相互作用被认为是主要的散射机制，而电子-电子相互作用完全被忽略。子带间和子带内的转换被同等对待。在电子温度近似中预测在低温区发生的S形非线性行为被去除。实验观察到的等离子体共振和回旋共振宽度的迟滞，如果有的话，可以归因于电子-电子相互作用。
Theoretical study is given of the high field transport of surface state electrons on the liquid 4 He. The explicit form of the electron distribution function is solved by the use of the Boltzmann transport equation where the electron-ripplon and electron-He gas interactions are considered as dominant scattering mechanisms, and the electron-electron interactions are completely neglected. Inter-subband and intra-subband transitions are treated equally. The S -shaped non-linear behaviors predicted to occur at low temperature region in the electron temperature approximation have been removed. Experimentally observed hysteresis, if any, in the widths of the plasmon resonance and cyclotron resonance may thus be attributed to the electron-electron interaction.
