Abstract: A method for accessing a service system includes: receiving fingerprint information of a to-be-verified terminal device and identification information of a to-be-verified user from a login computer system based on a service access instruction to access the service server; verifying, according to the fingerprint information of the to-be-verified terminal device and the identification information of the to-be-verified user, whether the to-be-verified terminal device is a specified device of the to-be-verified user based on a specified device database, the specified device database comprising identification information of each user and fingerprint information of a specified device of each user; determining, according to a result of the verifying, whether to allow the login computer system to access the service server according to the service access instruction; and if yes, sending a notification to the login computer system to enable the login computer system to access the service server.

Abstract: Disclosed are an anti-spalling blocking bar for a large cross-section coal gallery excavation work surface and a supporting method. The anti-spalling blocking bar comprises a blocking bar (1) and a support bar (7). Both a top portion of the blocking bar and an end of the support bar are provided with screw holes (2). A steel peg (5) is provided on an outer side of a bottom portion of the blocking bar. Locking teeth (6) is provided on an inner side of a mid-upper portion of the blocking bar, and a locking catch (8) is provided on one end of the support bar. The blocking bar and support bar are secured, using the screw hole and a screw bolt, to a temporary support device. After removing coal, a tool is used to hammer the blocking bar so as to wedge the steel peg thereof into a coalface (13). The locking catch of the support bar is held within the locking teeth to support a coal heading.

Abstract: Provided are a nimodipine water-soluble derivative, and a preparation method and a use thereof, belonging to the field of pharmaceutical chemistry. The nimodipine water-soluble derivative has the structural feature of general formula I and has a relatively high water solubility, and can be converted into nimodipine by an internal enzyme in blood or in the body, so that the nimodipine water-soluble derivative can be used as a nimodipine prodrug and a calcium ion antagonist for treating cardiovascular and cerebrovascular diseases.
