讨论了在非经典离子损失影响下，用自洽分析方法确定扭子等离子体的径向电场和损耗锥边界。考虑了损耗锥损耗、快离子与中性离子的电荷交换损耗以及异常损耗的双极部分的影响。分析了等离子体在CHS器件中的NBI加热过程。将理论结果与实验结果进行了比较。轨道损失和与中性离子的电荷交换损失增加了离子粒子的损失，使得径向电场比纯新古典计算的值更负。利用自洽电场分布估计了注入能量在穿透、直接轨道损失、电荷交换损失和整体加热之间的分配。
A selfconsistent analysis is discussed to determine the radial electric field and loss cone boundary in torsatron/heliotron plasmas under the influence of nonclassical ion losses. Effects of the loss cone loss, charge exchange loss of fast ions with neutrals, and the bipolar part of anomalous loss are taken into account. Analysis is applied to the NBI heated plasma in the CHS device. Comparison is made between theoretical results and experimental observations. The increased ion particle losses by the orbit loss and charge exchange loss with neutrals make the radial electric field more negative than the value of purely neoclassical calculation. The partition of the injection energy among the shine through, direct orbit loss, charge exchange loss and bulk heating is estimated by using the self-consistent electric field profile.
