Abstract: A diagnostic method and system for measuring potential and electric field of plasma are provided. According to operation parameters of a magnetic confinement fusion device and relevant parameter data of a plurality of candidate particle elements, signal-noise ratios are calculated. to select a neutral beam particle element. Beam trajectories varying in incident velocity, incident angle and sampling area are obtained by iterative calculation, and a preset parameter which enables the beam trajectories to pass through an entrance slit of an analyzer is obtained. A neutral beam that meets the preset parameter is injected into the plasma. An energy of the primary beam generated by collision ionization in a sampling area is measured, and potential of the sampling area is obtained according to law of conservation of energy. Sampling areas are detected to obtain potential spatial distribution of the plasma and a radial electric field, and the diagnostic is finished.

Abstract: A vehicle automatic networking apparatus with a first component and a second replaceable component includes a first identity recognition module on the first component and a second identity recognition module on the second component. The second module in a networking mode transmits a low frequency wake up signal through a low frequency signal transmission circuit to wake up the first module. A first identity recognition module low frequency sensor circuit senses the low frequency wake up signal, and responds by transmitting an identity code of the first component through a low frequency signal transmission circuit. A second module low frequency signal receiving circuit receives and stores the first component identity code. In a following data transmission, the second module sends data with the identity code, and a first component receiving apparatus identifies it. The first and second modules are both located rearward of a second component connection hitch.
