Abstract: A bismuth-doped bismuth phosphate photoelectrode modified by titanium carbide and a preparation method are provided. A first chitosan coating and a second chitosan coating both show electropositivity, and a two-dimensional Ti3C2 coating shows electronegativity, wherein the bismuth-doped bismuth phosphate photoelectrode modified by two-dimensional Ti3C2 is prepared by an electrostatic self-assembly method. The method is efficient, environment friendly and has simple operation steps; no precious metals are doped in reactions, and no pollutants are produced in reaction processes to meet a requirement of environmental protection; and the method has positive significance for putting the bismuth-doped bismuth phosphate photoelectrode modified by the titanium carbide into actual production. The bismuth-doped bismuth phosphate photoelectrode enhances synergistic effect of electrons and delays recombination time of photo-induced electrons and hole pairs.

Abstract: An adjustment method of moisture content and dense state for a hydrogel improved subgrade based on weather-resistance during an in-service period, including: step 1: carrying out surface cleaning and compaction of ground; step 2: preparing hydrogel improved subgrade raw material; step 3: paving the prepared material on the surface to form first-layer improved subgrade; and step 4: paving plain soil subgrade onto the first-layer. The method combines the water absorption and release function of the modified resin and the characteristic of the gel state thereof, to pave the improved subgrade in layers, which can absorb water and slightly expand when the water content in the subgrade is increased to a certain threshold value, and a strength and compactness protective layer can also be formed at the connection sections of the ground and the subgrade, and the subgrade and the pavement, to prevent the pot-cover effect from occurring.

Abstract: A low-complexity panoramic video coding method considering distortion temporal propagation is provided. By analyzing the inter-frame reference relationships under the random access coding structure and establishing the corresponding distortion propagation chain, the method utilizes distortion impact factors of coding units to adjust encoding parameters, thereby optimizing the encoding process. Furthermore, the method addresses the issue of oversampling arising from the varying geometric deformations in different latitude regions during the projection of spherical images in panoramic videos. This is achieved by adjusting coding parameters based on the ratio of area changes at different latitudes. The proposed approach significantly enhances coding performance.

Abstract: A surgical microscope diagnosis and treatment system comprises a microscopic observation module, a storage module, and an enhanced information image injection module. The microscopic observation module is configured to observe a target object to be observed. The storage module stores a radiatively imaged three-dimensional structure digital image of the target object. The enhanced information image injection module is used for projecting the radiatively imaged three-dimensional structure digital image into an observation field of the microscopic observation module in a manner of an optical image, so as to be superimposed on an optical image under a microscope in the observation field of the microscopic observation module to form a superimposed optical image.
