摘要:

在这封信中,我们提出了一个图灵模型的形成模式的可见光发射强度在大气压气体放电。在双反应物图灵模型中,电子密度和电子温度分别起激活剂和抑制剂的作用,激活剂的扩散系数远小于抑制剂的扩散系数,电离和激发态原子的激发是主要的反应过程.该模型预测的条纹在一个1D系统,这在定量上同意与实验结果的空间变化尺度长度。此外,该模型还预测了实验观察到的放电结构的变化时,输入功率和气体压力的变化。

英文摘要:

In this letter we propose a Turing model of the formation of patterns of visible light emission intensity in atmospheric pressure gas discharges. The electron density and the electron temperature take the roles of activator and inhibitor respectively in a two-reactant Turing model, with the activator diffusion coeffcient being much smaller than that of the inhibitor, and ionization and excitation from excited state atoms considered as the dominant reaction processes. The model predicts striations in a 1D system, which quantitatively agree with experimental results in terms of the spatial variation scale lengths. Additionally, the model also predicts changes in the discharge structure observed experimentally when input power and gas pressure are varied.
