Abstract: The present disclosure discloses a method for making an ice surface of an ice rink and an ice rink including the ice surface. In the method, a salt solution is applied to an ice surface. The salt solution contains anions. A concentration of the anions is in a range from about 0.63 mmol/L to about 10 mmol/L. The anions in the salt solution are selected from the group consisting of chloride ions, nitrate ions, bromide ions, iodide ions, chlorate ions, perchlorate ions, thiocyanate ions, and any combination thereof. The ice surface is maintained at a temperature of about −4° C. to about 14° C. to naturally freeze the salt solution.

Abstract: A method and system for implementing L3VPN based on a two-dimensional routing protocol. The method includes the following steps of: activating an L3VPN network to obtain a route destined to each user site; sending, by a user in a source user site, a packet to a user in a target user site, and sending the packet to an entry of a first edge routing device; performing encapsulation by the first edge routing device based on a public network IP address of the packet; and forwarding, by means of matching of two-dimensional routing, the encapsulated packet to an exit of the first edge routing device for decapsulation, and forwarding the same to the target user site via an entry of a second edge routing device.

Abstract: The present invention discloses an machining device based on a portable 5-DOF parallel module. The machining device based on a portable 5-DOF parallel module comprises: a table for moving a parallel module to increase the stroke of the machine tool such that the machine tool can machine large components and can also simultaneously conduct the mounting and the machining of workpieces at different stations; a CNC rotary table; and a portable 5-DOF parallel module. The portable parallel module has a large swing angle range, can conduct the conversion between vertical and horizontal machining modes and can achieve five-face machining in one setup in cooperation with the CNC rotary table. The parallel module can move flexibly, and can machine large and complex components after mounted on the sliding table. After the machining of the workpiece is completed, the parallel module can move to the position of a mounted component through the table to conduct the machining of the next component. Thus, the mounting and the machining of the workpiece are simultaneously conducted at different stations, and the utilization rate and the production efficiency of the portable parallel module are improved.
