中文摘要	为研究影响无极灯光效的主要因素,采用自制不锈钢腔体以及光谱仪等设备研究了填充气体类型、分压以及混合气体组分含量对Hg原子253.7 nm谱线强度的影响。实验结果表明:在Hg蒸气中掺入单一惰性气体的无极放电中,Hg原子253.7 nm谱线强度由强到弱的顺序为Ne>Ar>Kr,且随着填充气体分压的增大,Hg原子253.7nm谱线强度减弱;在Hg蒸气中混入总气体分压为50Pa的Ar-Kr混合气体时,随着Kr体积分数增大,Hg原子253.7 nm谱线强度先迅速增强而后逐渐减弱,在Kr气体体积分数为8%时达到最大值;而混入Ar-Ne混合气体时,Hg原子253.7 nm紫外谱线强度随Ne体积分数的增大先增强而后减弱,且在Ne气体积分数为80%时达到最大值。; In order to obtain the main factors affecting the efficiency of electrodeless lights, we investigated the influence of filling gas' s type, pressure and mixed gas component content on the 253.7 nm line intensity of Hg atom, using a homemade stainless steel cavity and a spectrometer. The experiment results show that, when Hg vapor is mixed with a single kind of inert gas, the order of 253.7 nm spectral line intensity of Hg atom from the strong to the weak is mixing with Ne, Ar, and Kr, and the intensity decreases with increasing pressure of any filling gas. When Hg vapor is mixed with mixed Ar-Kr gas which has a partial pressure of 50 Pa in total, the 253.7 nm spectral line intensity of Hg atom increases rapidly firstly and then decreases gradually with increasing volume fraction of Kr, and it reaches a peak at the Kr volume fraction of 8%. When Hg vapor is mixed with Ar-Ne gas of 50 Pa(partial pressure), the 253.7 nm spectral line intensity increases firstly and then decreases with increasing volume fraction of Ne, and it reaches a peak when the Ne volume faction is 80%.
