A method for mechanochemical treatment of solid wastes containing perfluorinated or polyfluorinated compounds is provided. It belongs to the field of environment-polluting wastes treatment, and comprises the following steps: mixing the solid waste containing perfluorinated or polyfluorinated compounds with the defluorination reagent under normal temperature and pressure conditions, putting the mixture into a planetary high-energy ball milling reactor; adopting the mechanochemical reaction to realize high-effective degradation and defluorination of perfluorinated or polyfluorinated compounds. When being adopted to degrade perfluorinated or polyfluorinated compounds, this method enjoys such advantages as simple treatment procedure, mild reaction conditions (conducted under normal temperature and pressure conditions), lower energy consumption and operating cost, complete degradation and defluorination of the target pollutants, completely inorganic and harmless end products and free of liquid or gas byproducts.

Embodiments of the present invention provide a method and system for reassigning traffic channel configuration, which is applicable to reassigning traffic channel configuration between a site A and a site B with the reassignment being initiated by the site A. The site A transmits a reassignment message to the site B, where the reassignment message carries reassigned traffic channel configuration. The site B determines whether the reassignment message is received correctly, and processes traffic data and transmits the traffic data to the site A according to a determining result. The site A processes the traffic data, and determines whether the reassignment message is correctly received by the site B through determining whether the traffic data are correct. The method and the system enable a base station to determine whether a terminal correctly receives a reassignment message without the terminal transmitting an acknowledgement message, which guarantees fluent communications between the two parties.
