汉英语境1
英译术语:
anisotropy
汉语语境:
分析结果表明，相比于纯一价氙等离子体鞘层参数，推力器中的多价态氙等离子体鞘层电势降略有降低，电子壁面损失增加，临界二次电子发射系数减小。推力器中的电子温度各向异性现象可以显著地加大出射电子能量系数，进而降低鞘层电势降，增强电子壁面相互作用。
英语语境:
Results show that in comparison with that of a pure univalent xenon plasma, the sheath potential drop and the critical secondary electron emission coefficient are decreased in mixed valence xenon plasmas, while the primary electron flux at the wall is increased. The electron temperature anisotropy in Hall thrusters thus significantly enhances the electron energy emission coefficient, and further reduces the sheath potential drop while intensifying the electron-wall interaction.
