通过粒子模拟研究，发现了在最大密度超过慢X模截止密度的等离子体中，入射的快X模（快X模）通过慢X模（慢X模）转变为电子伯恩斯坦模（B模）的新的模转换过程.转换后的B模式被发现有效地加热电子在过密的等离子体区域，当等离子体具有最佳的密度梯度在等离子体表面。
Through a particle-simulation investigation, a new mode-conversion process, through which an incident fast extraordinary mode (fast X mode) is converted into an electron Bernstein mode (B mode) via a (slow extraordinary mode slow X mode), is discovered in plasmas whose maximum density exceeds the cutoff density of the slow X mode. The converted B mode is found to heat the electrons efficiently in an overdense plasma region, when the plasma has the optimum density gradient at the plasma surface.
