提出了一个微波驱动硫灯的一维LTE模型，以帮助我们理解放电过程。灯的能量平衡一方面由欧姆输入决定，另一方面由传导热和分子辐射引起的输运决定。我们讨论了光谱中操作趋势的起源，给出了模型，并讨论了如何确定等离子体的材料性质。不仅模拟了温度分布和电场强度，还模拟了不同输入功率和充灯压力下灯在300~900 nm范围内的光谱。我们发现，模拟光谱显示了观察到的趋势，辐射功率随着输入功率的增加而线性增加，这也是从实验中发现的。
A one-dimensional LTE model of a microwave-driven sulfur lamp is presented to aid our understanding of the discharge. The energy balance of the lamp is determined by Ohmic input on one hand and transport due to conductive heat transfer and molecular radiation on the other. We discuss the origin of operational trends in the spectrum, present the model and discuss how the material properties of the plasma are determined. Not only are temperature profiles and electric field strengths simulated but also the spectrum of the lamp from 300 to 900 nm under various conditions of input power and lamp filling pressure. We show that simulated spectra demonstrate observed trends and that radiated power increases linearly with input power as is also found from experiment.
