A popularity data processing method includes receiving a trigger operation for a target page, obtaining one or more target elements in a display state from one or more elements included in the target page, and obtaining popularity data of the target elements based on the trigger operation. A target element of the one or more target elements is an element in the target page belonging to a first display type or a second display type. The first display type is an element type that enters a display state from a hidden state in response to a received display operation, the second display type being different from the first display type.

An elastic adjustable brake pad for use in a train, comprising a brake pad frame () provided with a fourth through hole (), a brake block assembly, and a spiral compression spring (); the brake block assembly comprises a brake block (), a rivet (), a Belleville spring (), and a rivet sleeve (), the brake block () comprising a friction block () and a static sheet steel back () fixedly mounted together, the rivet () passing through the brake block () and being sleeved in turn by the Belleville spring () and the rivet sleeve (); the fourth through hole () is a stepped counterbore, and the rivet () in the brake block () penetrates the fourth through hole () and extends outward therefrom, the spiral compression spring () being sleeved over the outside of the rivet sleeve (), and the outer side of one end of the rivet sleeve () being provided with a clamping groove clamped to an elastic retainer ring (), one end of the spiral compression spring () abutting a step on which a secondary counterbore () is located, and the other end thereof abutting the lower end face of the elastic retainer ring (); a plurality of anti-rotation pins are arranged between the static sheet steel back () and the brake pad frame (). The present brake pad has the advantages of automatically adjusting the brake clearance, ensuring the friction area at all times, improving brake efficiency, extending service life, and low manufacturing costs.

In a binocular steroscopic scanning radiographic imaging method, X-rays emitted by the same radiation source are used. The X-rays pass through a double-slit collimator to form two X-ray beam sectors, which are symmetric or asymmetric and have an angle between them. The X-ray beam sectors, after penetrating through an object under detection, are received by the left and right detector array, respectively, then converted into electric signals to be inputted to the respective image acquisition systems, and received by a computer processing system for image processing and displaying. A system corresponding to the method comprises a radiation source, a beam controller, two mutually connected arms of detector arrays, image acquisition systems connected respectively to each of the detector arrays and a computer processing system. The present invention can display the transmission images detected by each of the detector arrays as well as tomograms with different depth reconstructed from the transmission images according to the principle of parallax. The present invention is convenient, fast in detection and realizes with low cost the recognition of objects of different depths.
