  • 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.
