Abstract: A fast industrial CT scanning system and a method are provided. The scanning system includes X-ray sources, detectors, a rotating table, control boxes, and a control unit. The X-ray sources, the detectors, the rotating table, and the control boxes are all connected to the control unit. The rotating table is used for placing a specimen detected. Three X-ray sources are annularly and uniformly arranged at an interval of 120° by taking an axis of the rotating table as a center. Distances from the three X-ray sources to the specimen detected are equal. Each X-ray source is mounted in a corresponding control box. Three detectors are annularly and uniformly arranged at an interval of 120° by taking the axis of the rotating table as a center. Distances from the three detectors to the specimen detected are equal.

Abstract: A miniature temperature-controlled triaxial tester for testing unsaturated soil suitable for micro-computer tomography (CT) scanning and a method thereby. The triaxial tester includes a device body, where the bottom of the device body is fixed on a base, and the top of the device body is provided with a strain control device. The device body includes a vertically arranged polymethyl methacrylate shell, a PMMA inner cover is nested inside the PMMA shell, and a vacuum gap is formed between the PMMA shell and the PMMA inner cover; a pressure cell is formed by a space defined by the PMMA inner cover, a sample accommodating area for accommodating a test sample is arranged in the pressure cell, a heating element is arranged below the sample accommodating area and connected to a temperature control device, and a temperature sensor is arranged inside the PMMA inner cover and connected to a receiver.
