Abstract: The present invention discloses an electric heating thermal management system for an oil and gas transportation pipeline based on renewable energy and CO2 energy storage. It transmits the feedback data value through a data collection device arranged in the pipeline to the early warning device by the control device. After analysis and processing, the early warning device can feed back the data value to the control device and the remote operation device in two modes. Different degrees of heating amount can be generated for the oil and gas transportation pipelines at different positions in different modes. Hierarchical and distributed management control for the oil and gas transportation pipelines can be targetedly conducted in unblocked, easily blocked and blocked positions of the oil and gas transportation pipeline. The present invention couples the renewable energy electricity supply device and the CO2 energy storage device.

Abstract: A method for measuring a surface shape of a honeycomb core includes the following steps: coating a reflective film on the surface of the honeycomb core to be measured, using a vacuum adsorption method to adhere the reflective film closely to the surface of the honeycomb core to be measured, and recessing the reflective film at a honeycomb cell downwards; and performing scanning measurement on the reflective film on the surface of the honeycomb core to be measured to obtain the heights of a honeycomb wall of the honeycomb core at different spatial positions. A device carries out the measurement of the surface shape of a honeycomb core.
