Nonpotential magnetic energy promptly released in solar flares is converted to other forms of energy. This may include nonthermal energy of flare-accelerated particles, thermal energy of heated flaring plasma, and kinetic energy of eruptions, jets, upflows/downflows, and stochastic (turbulent) plasma motions. The processes or parameters governing partitioning of the released energy between these components are an open question. How these components are distributed between distinct flaring loops and what controls these spatial distributions are also unclear. Here, based on multiwavelength data and 3D modeling, we quantify the energy partitioning and spatial distribution in the well-observed SOL2014-02-16T064620 solar flare of class C1.5. Nonthermal emission of this flare displayed a simple impulsive single-spike light curve lasting about 20 s. In contrast, the thermal emission demonstrated at least three distinct heating episodes, only one of which was associated with the nonthermal component. The flare was accompanied by upflows and downflows and substantial turbulent velocities. The results of our analysis suggest that (i) the flare occurs in a multiloop system that included at least three distinct flux tubes; (ii) the released magnetic energy is divided unevenly between the thermal and nonthermal components in these loops; (iii) only one of these three flaring loops contains an energetically important amount of nonthermal electrons, while two other loops remain thermal; (iv) the amounts of direct plasma heating and that due to nonthermal electron loss are comparable; and (v) the kinetic energy in the flare footpoints constitutes only a minor fraction compared with the thermal and nonthermal energies.

太阳耀斑中迅速释放的非势能磁能被转化为其他形式的能量。这可能包括耀斑加速粒子的非热能、加热的燃烧等离子体的热能，以及喷发、射流、上流/下流和随机（湍流）等离子体运动的动能。控制这些组件之间释放的能量分配的过程或参数是一个悬而未决的问题。这些成分如何在不同的扩口环之间分布以及控制这些空间分布的因素也不清楚。在这里，基于多波长数据和 3D 建模，我们量化了观测良好的 C1.5 级太阳耀斑 SOL2014-02-16T064620 中的能量分配和空间分布。该耀斑的非热辐射显示出持续约 20 秒的简单脉冲单峰光曲线。相比之下，热辐射显示出至少三个不同的加热事件，其中只有一个与非热成分有关。耀斑伴随着上流和下流以及巨大的湍流速度。我们的分析结果表明 (i) 耀斑发生在至少包括三个不同通量管的多回路系统中；(ii) 释放的磁能在这些回路中的热成分和非热成分之间分配不均；(iii) 这三个燃烧回路中只有一个包含能量上重要的非热电子，而另外两个回路保持热电子；(iv) 直接等离子体加热量和非热电子损失引起的量相当；
