This invention relates to the field of hydrogen absorption technology, specifically to a hydrogen-absorbing particle, its preparation method, and its application, comprising the following steps: S1. Granulation: First, hydrogen-absorbing powder is dissolved in a solvent, then a binder is added for granulation to obtain a soft material; S2. Sizing: The soft material is then dried and granulated, and magnesium stearate is added to the granulated soft material for mixing; S3. Tableting: The soft material with added magnesium stearate is tableted. The preparation process of this invention is simple and easy to operate; the tableting method results in good forming effect, prevents loosening, and facilitates the use and replacement of composite hydrogen-absorbing materials.

The application discloses a bearing for a vertical shaft, comprising an outer ring and an inner ring, two rows of retainers are arranged between the outer ring and the inner ring, rolling bodies are assembled in the retainers, the retainers comprise an upper edge part, a pocket part and a lower edge part, the upper edge part is arranged along the axial direction of the outer ring, the lower edge part is arranged along the radial direction of the outer ring, the pocket part is arranged obliquely, a plurality of pockets are arranged on the pocket part, pocket beams are formed between adjacent pockets on the pocket part, a plurality of outer convex ribs are arranged obliquely on the outer circumferential wall of the retainer, a plurality of inner convex ribs are arranged obliquely on the inner circumferential wall of the retainer, and the inner convex ribs and the outer convex ribs are arranged at positions corresponding to the pocket beams. The bearing has the advantages of simple structure, effective solution to the problems of uneven distribution of lubricating grease, double-row bearing lubricating grease flow and poor sealing reliability in the prior art, and effective improvement of the operation stability and service life of the bearing.

The invention relates to the technical field of information transmission, in particular to an online sports competition information transmission system and method.The online sports competition information transmission system comprises an acquisition module, a transmission module, a storage module, a grading module and a calling module, the acquisition module is used for acquiring actual sports competition conditions, and acquisition data are obtained; the transmission module transmits the acquisition information and transmits the acquisition information to the storage module; the storage module stores and backs up the collected information to obtain stored data, and the grading module grades the servers and receives the transmitted collected data; according to the system, the transmission area and the storage area are separated, and the server is graded, so that the phenomena of large data transmission demand and transmission lagging caused by the fact that a campus and other places with dense personnel share one server are avoided, and the service life of the server is prolonged. And when a part of players pull the competition progress, the storage data in the corresponding time period is directly called, and the data transmission speed is not influenced.
