The application discloses a sustained combustion type plasma nuclear fusion chamber. The chamber comprises a shell, a plasma channel is arranged in the shell, the plasma channel is a tapered pipeline from an inlet end to an outlet end, the inlet of the plasma channel is communicated with the outlet of an electromagnetic acceleration channel of a plasma electromagnetic acceleration device, the inner end of the plasma channel is communicated with a plasma nuclear fusion cavity, the inner wall of the plasma nuclear fusion cavity is an arc surface, a nuclear fusion sustained combustion cavity is arranged on the inner wall of the plasma nuclear fusion cavity, and the nuclear fusion sustained combustion cavity is filled with nuclear fusion fuel. The sustained combustion type plasma nuclear fusion chamber can make plasma enter the plasma nuclear fusion chamber and generate primary nuclear fusion, and the primary nuclear fusion can transmit heat to the nuclear fusion fuel in the nuclear fusion sustained combustion cavity, thereby triggering secondary nuclear fusion.

This application discloses a plasma model analysis method and apparatus for space charging and discharging effects. The method includes: determining the orbit type and the space region traversed during on-orbit operation; determining the plasma model of the outer space plasma fusion model in the traversed space region; obtaining plasma parameters of the traversed space region based on data from the current solar activity period and / or the current geomagnetic activity period; analyzing the charging and discharging effects occurring on the spacecraft surface based on the plasma parameters; using an intrinsic plasma model in the intrinsic region and a transitional fusion model in the transition region, determining the range of the transition region based on the boundary between two adjacent intrinsic regions; dividing the transition region into multiple sub-regions based on the range and division strategy of the transition region; determining the fusion mode of each sub-region for each sub-region, obtaining a transitional fusion model corresponding to the transition region. The plasma parameters obtained through plasma model analysis are more accurate.

The present invention discloses a low-temperature plasma fusion ultraviolet special pathogen coronavirus disinfection technology device, which belongs to the field of disinfection technology. The device includes a low-temperature plasma airflow generator, an ultraviolet generator and an airflow circulation system; the ultraviolet generator is located in front of the low-temperature plasma airflow, and the disinfection airflow formed by the fusion of the low-temperature plasma airflow and ultraviolet light is sprayed onto the surface of the sample to be disinfected, thereby disinfecting the pathogens and coronaviruses on the sample surface; the disinfection airflow circulation is used to improve the disinfection efficiency and reduce O3 emissions. Using a working voltage of 33±5kV, a frequency of 13±5kHz, and a fusion of ultraviolet light with a wavelength of 222±10 nanometers, 6Log10CFU / cm2 of Staphylococcus aureus is disinfected and killed in 160s, and 4.28log10TCID50 / cm2 of coronavirus (SARS-CoV-2) is disinfected and killed in 30s. The efficient disinfection efficiency of this technical device for microbial coronaviruses will provide core technical device support for the development of special equipment for disinfection of pathogens and coronaviruses in modern cold chain logistics.
