A new branch of theoretical physics, quantum plasmadynamics (QPD), will be applied to plasmas under extreme conditions of magnetic field and density, to plasma-neutrino effects and nonlinear radiation. Magnetic energy dissipation in solar flares will be attributed to a large number of coupled, local, transient, anomalously resistive regions excited by current filamentation. The model will include nonlocal energy release at Alfvenic fronts, 3D reconnection at magnetic nulls, and bulk energization of electrons. `Coherence? in sources of coherent emission will be quantified and a model for its interpretation for highly intermittent wave growth will be formulated.

在极端的磁场和密度条件下，将应用于等离子体的质量血质动力学（QPD）的理论物理学的新分支，将其应用于等离子体 - 中性效应和非线性辐射。 太阳耀斑中的磁能耗散将归因于大量耦合，局部，瞬态，异常电阻的区域，该区域受电流丝的激发。该模型将包括在Alfgenic Fronts处的非局部能量释放，磁性磁性的3D重新连接以及电子的大量能量。 `连贯？将在相干发射的来源中进行量化，并将制定其对高度间歇性波生长的解释模型。
