Abstract: Disclosed are a rotating shaft mechanism and a foldable mobile terminal. The rotating shaft mechanism provided in the embodiments of this application is mainly applied to a foldable mobile terminal, so as to implement unfolding and folding of two main body parts of the foldable mobile terminal. When the elastic support member is in a compressed state, at least some segments of the first part and the second part overlap in a floating direction, and the second part provides a compressed deformation space for a part or all of the first part. In this way, a height of the elastic support member in overall compression and deformation is reduced, and an ultra-thin design requirement of the foldable mobile terminal is met.

The folding assembly is applied to a foldable electronic device, and is configured to carry a flexible display screen. The folding assembly includes a shaft base, a first housing, and a second housing. The first housing and the second housing are respectively disposed on both sides of the shaft base. A door plate swing arm is located above the shaft base and is disposed on each of both sides of a center line of the shaft base, one end of each door plate swing arm is rotatably connected to the shaft base, and the other end of each door plate swing arm is rotatably connected to the first housing or the second housing.

Abstract: A data storage method and apparatus are provided. First information of to-be-stored data is first obtained. The first information includes at least one piece of information: a type of the to-be-stored data, a name of the to-be-stored data, and a user identifier corresponding to the to-be-stored data; An expected storage location of the to-be-stored data is determined based on whether the first information of the to-be-stored data meets a condition. At least one data packet in a plurality of data packets of the to-be-stored data is stored in the expected storage location.

Abstract: A host and a storage system communicate with each other by using a NVMeoF protocol are provided. In some embodiments, the host accesses a logical disk of the host by using a control node in the storage system, and sends a state query command to the control node. The state query command is configured to instruct the control node to report a path state of a path corresponding to the control node. Still in those embodiments, the host receives the path state reported by the control node. When the received path state indicates that the logical disk includes an access interval, the host sends an interval query command to the control node; receives access interval information reported by the control node; and records a mapping relationship between the control node and the access interval information.

Abstract: In a method for processing a server message block (SMB) service fault, a first storage device generates a file handle according to a first file open instruction from a host, and sends the file handle to a second storage device. The second storage device stores the file handle as a backup handle. The second storage device activates an Internet Protocol (IP) address of the first storage device according to fault information from the first storage device, and establishes a communication connection to the host. After the second storage device determines a file handle matches the handle identifier, the second storage device opens a file. Hence, when a storage device that processes an SMB service is faulty, the SMB service may be taken over by a secondary storage device such that the SMB service is executed without interruption.

Abstract: A catalyst for effective oxidation of volatile organic compounds (VOCs) includes 0.010-2 wt. % of a noble metal such as platinum in combination with 0.5-15 wt. % of a transition metal oxide such as chromium oxide (Cr.sub.2 O.sub.3), with at least the noble metal being deposited as a thin outer layer or shell not exceeding 0.10 mm thickness on a porous inert support such as alumina or silica having surface area of 10-400 m.sup.2 /g. The catalyst is made by adding the transition metal oxide such as chromium oxide (Cr.sub.2 O.sub.3) to the support material particles, and then subsequently mixing a solution of ammonium platinum nitrate with a suitable carrier liquid so as to form a "cluster" structure on the support material and which limits penetration of the active noble metal into the porous support, then drying, reducing, and calcining the metals-loaded support material.
