Abstract: An integrated teaching system for interaction and examination of ear acupoints includes a placement table, and a mounting plate rotatably mounted on the placement table by a first connecting shaft. Two ear acupoint models are symmetrically mounted on two sides of the mounting plate, respectively. The system further includes a support frame and a second connecting shaft fixed on the support frame, the second connecting shaft is connected to the first connecting shaft by a gear set, the second connecting shaft is rotatably connected to a mounting frame fixed on the placement table, an end of the support frame away from the placement table is inserted into a fixing sleeve and is slidable along the fixing sleeve, a lifting drive part is disposed in the support frame and connected to the fixing sleeve, and the lifting drive part is connected to the mounting frame by a transmission part.

Abstract: A data acquisition method for three-dimensional high-density resistivity based on arbitrary electrode distribution, comprising the following steps: evenly providing measurement points in a predetermined measurement area, and selecting endpoint positions and directions of electrode pairs according to surface conditions; sequentially moving a power supply to each of the measurement points according to the identification numbers, with the electrode pair at the current point as the power supply electrode pair, and the electrode pair within the effective measurement circle corresponding to the current point as the measurement electrode pair; continuing the process until all measurement points are powered, and a rolling measurement of the entire measurement area is complete.
