摘要

摘要: 六氟化硫（SF₆）和三氟溴甲烷（CF₃Br）是目前发现的在电离层释放作用效果较好的两种物质.利用气相色谱elax-elax电子捕获检测器（GC-ECD）对SF₆和CF₃Br的电子捕获能力进行实验研究，并采用密度泛函理论（DFT）对两种物质进行理论计算，最后对实验结果和理论计算结果进行对比分析.GC-ECD实验结果表明，SF₆和CF₃Br在ECD检测器上均有较好的响应，且CF₃Br在ECD检测器上的响应强于SF₆.DFT理论计算结果表明，SF₆和CF₃Br都具有捕获电子的潜力.综合实验结果与理论计算结果可知，SF₆和CF₃Br都具有捕获电子的潜力，且均有较好的电子捕获效果，相对于SF₆，CF₃Br电子捕获效果更好.

Abstract: The sulfur hexafluoride (SF₆) and trifluoromethane (CF₃Br) are two kinds of ionospheric modification agents. The GC-ECD and DFT evaluation method for vacuum electron absorption are designed, and two methods are used to evaluate the SF₆ and CF₃Br. Finally, the results of two methods are compared and analyzed. The results of GC-ECD evaluation method show that SF₆ and CF₃Br have better response on ECD detector, and the response of CF₃Br on ECD detector is stronger than that of SF₆. The results of DFT evaluation method show that both SF₆ and CF₃Br have superior electron absorption capacity. Considering the results of the GC-ECD and DFT evaluation method, it can be seen that both SF₆ and CF₃Br have obvious electron absorption capacity and have superior electron absorption effect. The electron absorption effect of CF₃Br is superior to that of SF₆.
