    Abstract: A supercritical carbon dioxide state monitoring and control system based on infrared spectrum characteristic analysis. The system includes: a test section for carbon dioxide to pass through; an infrared light source emitting a detection beam to the carbon dioxide passing through the test section; an infrared spectrometer receiving and analyzing the detection beam passing through the carbon dioxide; and a pressure control module controlling pressure of the carbon dioxide at a set value. In addition, the system also includes a temperature control module capable of monitoring and adjusting temperature of the supercritical carbon dioxide. The supercritical carbon dioxide state monitoring and control system may monitor and control a state of the carbon dioxide at an inlet of an apparatus under an actual operation condition in a Brayton cycle system, which improves working performance of the apparatus in the Brayton cycle system, thereby improving overall efficiency of the Brayton cycle system.

    Abstract: A turbine for solar thermal power generation and a Brayton cycle are disclosed. The turbine includes a blade which has a cooling working medium inlet and a cooling working medium jet orifice. The blade is provided as a cavity with hollow interior; the cooling working medium inlet is located inside the blade; the cooling working medium jet orifice is provided on the blade surface on which is provided a spectral conversion coating; the spectral conversion coating converts heat on the blade surface into conversion characteristic band radiation which is radiation energy adjacent to cooling working medium characteristic band radiation of a cooling working medium. The turbine adopts a characteristic spectral coating and a jet cooling to enhance the cooling effect for a turbine blade and to improve the system efficiency of the Brayton cycle.

    Abstract: A denoising method based on a multiscale distribution score for a point cloud includes: constructing a two-layer network model based on multiscale perturbation and point cloud distribution, where the two-layer network model includes a feature extraction module for extracting a feature of the point cloud and a displacement prediction module for predicting a displacement of a noise point; constructing a point cloud noise model for improving a denoising effect and retaining a sharp feature and avoiding reducing quality of point cloud data; extracting a global feature h by inputting the point cloud data into the feature extraction module; iteratively learning the displacement of the noise point by the displacement prediction module according to a feature obtained by the feature extraction unit; and defining a loss function of network training, and completing convergence under the condition that the loss function reaches a set threshold or a maximum number of iterations.
