摘要:
A method for charging for a service is provided. The method includes: receiving, by a data service management device, submitted current communication service scenario information of a user; searching, by the data service management device, for priority information of charging in an account of the user, in a mapping relation between a communication service scenario and a charging priority of the account, according to the received current communication service scenario information of the user; pricing, in the account of the user according to the found priority information, and submitting a priced result to an intelligence network; and charging, by the intelligence network, the account of the user sequentially according to the submitted priced result. A device and a system for charging for a service, and a service management device are also provided.
摘要:
A method, and product thereof, for modifying the surface of recycled sulfur-cured rubber via surface devulcanization that minimizes alteration of the network structure of the recycled sulfur-cured rubber, while generating strong tack between mixed recycled rubber and fresh rubber for optimal adhesion upon subsequent co-curing. In one embodiment, the surface of recycled rubber is devulcanized by treating recycled rubber with a thiol and a base dissolved in a solvent that does not effectively penetrate and only minimally swells vulcanized rubbers.

摘要:
A vulcanizable rubber composition is includes a silica filler and a substituted catechol moiety. The substituted catechol moiety having a catechol end group with an organic substituent at the 3 or 4 position of the catechol ring, the organic substituent including a hydrocarbon moiety bound to the catechol ring and having at least 2 carbons.
