Embodiment Construction
[0041] The present invention will be further described below in conjunction with technical solutions and accompanying drawings.
[0042] Such as Figure 1-Figure 4 As shown, the PC host computer 1 is connected to the high voltage generator 2 and the temperature control unit 7 to control the total output voltage of the high voltage generator 2 and the time variation curve of the polarization temperature. The high-voltage generator 2 is connected in parallel with the fixed end 19 of the voltage controller 3; the lower electrode connection plate 11 is connected with the sliding end 20 of one of the voltage controllers 3, and a high voltage is set to it; several elastic telescopic probes 13 are connected with the rest The sliding end 20 of the voltage controller 3 is connected, and the voltage output of the elastic telescopic probe 13 with different sizes is realized by adjusting the resistance of the voltage controller 3, and the output voltage acts on the required polarization t...
