Embodiment Construction
[0015] The embodiment of the present invention: A method for simulating the dust environment on the moon surface, the atmosphere in the cavity is evacuated by a vacuum device to make the vacuum degree approximate to the moon surface environment; the dust sample is placed in the sample tank in the cavity, and the temperature is -190~ Adjust the temperature of the dust sample in the range of 150℃, use a microporous film to seal the dust sample in the sample tank; use deep ultraviolet spectroscopy to irradiate the dust sample with ultraviolet light, and charge the dust sample through the external photoelectric effect; then use a double-plane structure high-voltage electric field The board applies radio frequency voltage to generate radio frequency electric field in the test area, which is used to attract the charged dust sample to float; the dust sample generates electrostatic migration after being excited by the spectrum, which causes itself to be positively charged, and is attract...
