Abstract: A method for configuring an account of a cloud device including obtaining a sub-account corresponding to a currently logged-in primary account, wherein the primary account has a permission to access a cloud resource, and the sub-account has a part or all of the permission of the primary account; and importing the sub-accounts into the target cloud device to log in to the target cloud device through the sub-account to perform operation and maintenance on the target cloud device, wherein the cloud resource includes the target cloud device. The present disclosure solves the technical problem that, in the conventional techniques, the gateway account needs to be created for each gateway separately, which causes the complicated account configuration of the gateway.

Abstract: A Nickel free high manganese YW35 steel which has high strength and high tenacity at low temperature, and a fishplate made of the same. The YW35 steel for steel rail fishplate is produced by adding a selected amount of Molybdenum and microelement Vanadium and Niobium in a high Manganese steel and reducing the carbon content thereof, to thereby improve the low temperature property of the steel. The YW35 steel has (by weight percentage): C: 0.32˜0.40, MN: 1.10˜1.30, Is: 0.30˜0.50, p: <0.035, S: <0.035, MO: 0.15˜0.25, V: 0.06˜0.20, NB: 0.04˜0.07, Cu: <0.20, and a balancing amount of Fe.
