Abstract: An accelerated wear device for a ceramic tile and a wear test method thereof. The accelerated wear device includes an X-axis drive mechanism; a Z-axis drive mechanism, disposed on the X-axis drive mechanism; a rotary friction mechanism, disposed on the Z-axis drive mechanism; and an abrasive tool seat, disposed on the rotary friction mechanism, where the abrasive tool seat is used for mounting a wearing part, and drives the wearing part to perform a friction motion with a to-be-tested ceramic tile under the drive of the X-axis drive mechanism, the Z-axis drive mechanism and the rotary friction mechanism.

Abstract: A test method for anti-slip long effectiveness of an anti-slip ceramic tile. The test method includes: performing a wear test on a testing surface of a to-be-tested anti-slip ceramic tile; performing an anti-slip performance test on the worn testing surface, to obtain a wear test value; and determining an anti-slip long effectiveness grade of the to-be-tested anti-slip ceramic tile according to the wear test value. In the embodiments, the worn to-be-tested anti-slip ceramic tile is subjected to the anti-slip performance test, to obtain the anti-slip long effectiveness grade, thus explaining the performance of the worn anti-slip ceramic tile, which is conductive to determining the long effectiveness anti-slip performance of the anti-slip ceramic tile, and provides the long effectiveness anti-slip performance test method and determination basis for the manufacturing of the anti-slip ceramic tile.

Abstract: The present invention discloses a method for acquiring node information, and a Client and a server, wherein the method includes: a Client receiving a Get command sent from a server, acquiring values of nodes in all items in the Get command, and determining that acquirement of values of nodes in partial items fails; and the Client sending to the server a response message which carries a new status value, wherein the new status value is adapted to indicate that acquirement of values of nodes in partial items fails when a Get command is executed, and the response message also carries a predetermined tag, wherein the predetermined tag is adapted to packet information of nodes in items in which acquirement of values is successful. By the above technical solution of the present invention, useful nodes can be acquired more effectively, nodes which can not be acquired can be located.

Abstract: A method for partially locking functions of a terminal is disclosed, which includes the following steps: a device management server receives and analyzes a partially locking request message to obtain a terminal identifier and a designated call identifier which are included in the message; and sends a partially locking command to a terminal corresponding to the terminal identifier, wherein the partially locking command carries the designated call identifier and instructs the terminal to modify a functional attribute of the terminal per se to only answering a call corresponding to the designated call identifier. Another two methods for partially locking functions of a terminal, a device management server, a terminal, and a system for partially locking functions of a terminal are further disclosed.

Abstract: A method, device and system for updating a security algorithm of a mobile terminal are disclosed in the present invention. The method includes the steps of when a communication connection between a mobile terminal and a network side is established, transmitting a Device Management (DM) request message for obtaining state related information on a designated type to the mobile terminal; receiving the state related information on the designated type returned by the mobile terminal; and obtaining an algorithm identifier corresponding to the state related information and indicating the mobile terminal to update the security algorithm used locally according to the algorithm identifier. It is able to ensure the usage security of mobile terminals according to the present invention.

Abstract: A method for transmitting a large object and a server is provided. The method includes: after a client or a server initiates a device management session, the server sending to the client a large object transmission command which carries large object transmission data, wherein a difference between the maximum number of message bytes (MAXMSGSIZE) supported by the client and the number of bytes of the large object transmission data is greater than or equal to a preset value; and the server receiving an execution result of the large object transmission command returned by the client, and executing subsequent transmission operations based on the execution result.
