The influence of anisotropic potential energy and interaction between polar molecules on power absorption in chemical reactions with linear reaction dynamics in a weak alternating electric field is studied theoretically according to the reaction-diffusion equation. The expression for transient power loss is derived using two methods, electrodynamic method and equivalent circuit method, based on the electric energy conservation equation. Numerical calculations are carried out, and the results show that both the anisotropic potential energy and the interaction between polar molecules have a strong impact on energy dissipation and storage. For the anisotropic potential energy, when the applied dimensionless anisotropy is equal to 1, the power loss density increases about 32% at a low reaction rate and 27% at a high reaction rate compared to the case without anisotropic potential energy. When the dimensionless anisotropy is equal to -1, the power loss is suppressed and is reduced about 27% and 24% at low and high reaction rates, respectively. On the other hand, for the interaction between polar molecules, the power loss density decreases about 10% and 30% with low and high interaction potential energies, respectively. In addition, if the reaction rate is relatively high, the power loss will quickly decrease due to the end of the reaction process.
根据反应扩散方程，从理论上研究了弱交变电场中具有线性反应动力学的化学反应中各向异性势能和极性分子间相互作用对功率吸收的影响。基于电能守恒方程，采用电动方法和等效电路方法两种方法推导了瞬态功率损耗的表达式。进行了数值计算，结果表明，各向异性势能和极性分子间相互作用对能量耗散和存储都有强烈影响。对于各向异性势能，当施加的无量纲各向异性等于1时，与无各向异性势能的情况相比，在低反应速率下功率损耗密度增加约32%，在高反应速率下增加约27%。当无量纲各向异性等于 -1时，功率损耗受到抑制，在低反应速率和高反应速率下分别降低约27%和24%。另一方面，对于极性分子间的相互作用，在低相互作用势能和高相互作用势能下，功率损耗密度分别降低约10%和30%。此外，如果反应速率相对较高，由于反应过程结束，功率损耗将迅速降低。
