The embodiment of the invention discloses an access method and an access system for internet services. The access method comprises the following steps: a RADIUS (Remote Authentication Dial In User Service) server allocates the corresponding authorization class for a user according to the authorization result of dial for a user PPPOE (Point To Point Protocol Over Ethernet) and informs a policy server; the policy server issues a Portal page corresponding to the authorization class to a user terminal through a Portal server, wherein an internet using attribute query and application modification entry is set on the Portal page; after receiving an internet using attribute query and application modification request transmitted by the user through the internet using attribute query and application modification entry on the Portal page, the Portal server forwards the internet using attribute query and application modification request transmitted by the user to the policy server; the policy server instructs a BRAS (Broadband Remote Access Server) to modify internet using attribute information of the user and opens the access permission corresponding to the internet using attribute requested by the user to query or modify; the user accesses to the internet based on the modified internet using attributes through the user terminal. According to the embodiment of the invention, an internet using attribute interaction channel between an operator and the user can be established after the PPPOE authentication is ended.

This invention provides a method for realizing a unified dynamic address distribution to different types of users which is to add a DHCP relay agent module at the RADIUS service end to process the requests of applying for or releasing the network address of RADIUS server to DHCP server and coordinate the data communication between them. This invention enables RADIUS users to apply for/release IP addresses to the DHCP server by the DHCP relay agent module. Ordinary network users can apply for/release IP addresses by the DHCP server to realize a unified dynamic address distribution to different types of users in large network.

The invention discloses debuggable chemical cleaning equipment, which comprises an installation plate. An installation fixing mechanism is arranged on the outer side of the lower end of the installation plate, a rotating motor is installed in the middle of the upper end of the installation plate, a rotating shaft is arranged at the output end of the rotating motor, the lower end of the rotating shaft is connected with a rotating disc, a telescopic cylinder is arranged on the lower end face of the rotating disc, a telescopic rod is arranged at the output end of the telescopic cylinder, the lower end of the telescopic rod is connected with a lifting seat, the height of the lifting seat is adjusted through the telescopic cylinder, an enclosing block is arranged on the outer side of the lowerend of the rotating disc, and a plurality of sliding holes are formed in theenclosing block in an array mode. According to the debuggable chemical cleaning equipment, the structure is simple and reasonable, under driving of a regulating motor, a regulating disc drives a transmission connecting rod to rotate, so as to drive a guiding rod to slide along the sliding holes, in the way, adjustment of the clearing radius of a clearing brush is completed, the clearing height of the clearing brush can further be adjusted through the telescopic cylinder, the inner walls at different positions are cleared conveniently, in the way, the disadvantages of existing devices are eliminated, and practicality is high.

The invention belongs to the technical field of preparation of adhesives, and relates to a preparation method of an adhesive for making a board from crop straws, which comprises the following steps: dissolving diphenylmethane diisocyanate and polyether glycol NJ-330 in acetone; and by using dibutyltin dilaurate as a catalyst, adding hydroxypropyl methacrylate to perform termination, and adding fluorine-containing acrylate monomer to react by using azodiisobutyronitrile as an initiator, thereby obtaining the adhesive. The adhesive prepared by the method provided by the invention is free of free formaldehyde monomer. The fluorine element is introduced into an isocyanate adhesive system; fluorine atoms with lower polarizability, strong electronegativity and small Van der Waals radius can be combined with carbon atoms to form a high-bond-energy C-F bond, and the main group -CF3 of the fluorocarbon compounds has extremely low surface energy, so that the adhesive has high stability; after the adhesive forms the film, the film has favorable water resistance and mechanical properties, has strong bonding action with the straws subjected to surface treatment; and the adhesive can be used for preparing an artificial straw board according to a common artificial fiber board production technique.

The invention discloses a radiating device of an LED lamp. The radiating device is characterized by comprising an upper radiator and a lower radiator, wherein the upper radiator comprises a base, and a boss upwards projected from the center of the base; the boss is perpendicular to the base, and is provided with a horizontal light source surface at the top; the size of the light source surface is equivalent to the size of an LED light source fixed thereon; the light source surface and the LED light source have an excellent heat conducting channel; the cross section radius of the boss is kept consistent from the light source surface to the base; the lower radiator is matched below the base of the upper radiator; the lower radiator and the base have a heat conducting channel; a light emitting plane of the LED light source is covered with a diffusion lens; and the diffusion lens diffuses light rays of the LED light source to a whole space. The radiating device of the LED lamp keeps excellent heat conductivity of stamped aluminum alloys, is higher in precision, prevents the secondary processing, saves the cost, and is fast in processing time.
