A high-temperature and high-pressure core displacement test system includes a CT scanner configured to perform CT scanning, a gripper system configured to grip a core, a machine tool configured to move the gripper system to the CT scanner for CT scanning, a gripper load control system configured to heat and input a fluid into or/and receive a fluid output from the gripper system, and an acquisition and data analysis system configured to acquire a temperature and a pressure within a core gripping cavity, and detection data of the CT scanner and strain rosettes for analysis. According to the high-temperature and high-pressure core displacement test system and method, the strength of the gripper system in a high-temperature and high-pressure environment is improved, the projection performance of CT rays is ensured, and the optical fiber positioning precision and the core deformation measurement precision in a CT rapid scanning state are improved.

A processor is configured to acquire instruction information for setting the radiography apparatus to a power-saving mode in which power consumption is smaller than power consumption in a case where the radiography apparatus is operated, and information on a maintenance time during which the power-saving mode is maintained, set a holding temperature of the detector during the power-saving mode in accordance with the maintenance time in a case where the maintenance time is equal to or longer than a predetermined first threshold value, and control driving of a temperature adjuster such that the temperature of the detector is set to the holding temperature.

A method for determining a deformation field of at least one layer of paint applied to a support during crosslinking of the layer or the layers of paint is disclosed. The method includes a step (E1) of provision of a sample, a step (E2) of 3D tomographic measurement of the sample and a set of successive steps(S) repeated iteratively comprising a step (E3) of dynamic mechanical analysis of the sample subjected to at least one temperature cycle (C), a step (E4) of 3D tomographic measurement of the sample, a step (E5) of determining a deformation field of each layer of paint of the sample.
