This invention relates to a high molecular weight nylon powder composition for 3D printing, its preparation method and use. The composition comprises: 100 parts by weight of high-viscosity nylon powder, 1-5 parts by weight of a flow agent, and 0.1-1 parts by weight of an antioxidant; the high-viscosity nylon powder is one or more selected from nylon 6, nylon 66, nylon 11, nylon 12, nylon 612 and nylon 610; or the powder composition is obtained via polymerization reaction of the raw materials comprising the following components, based on the weight parts of lactam monomers or amide monomers: 100 parts by weight of lactam monomers or amide monomers, 0.005-1 parts by weight of a catalyst, and 0.1-1 parts by weight of an antioxidant. The high molecular weight nylon powder composition prepared in the present invention has a particle diameter in the range of 20-100 micrometers, good powder spreading performance, and is suitable for the 3D printing process, and the product of the high molecular weight nylon powder composition has good mechanical properties, good dimensional stability and low manufacturing cost.

Nylon powder composition for 3D printing, and preparation method and application thereof

A virtual switching method, a related apparatus, and a computer system are provided. The method includes the Host configures virtual environment between a source node and a target node in combination with an agent module, receiving a first message sent by a source node, where the first message is used to request a first virtual machine to perform switching processing on to-be-switched data, where the to-be-switched data is sent from the source node to a target node and at least one of the source node and the target node is a second virtual machine; and determining a second message according to an address of the target node contained in the to-be-switched data and a configured port mapping table, and sending the second message, where the second message is used to instruct the target node to acquire the to-be-switched data from a storage device of a hardware layer.

Virtual switching method, related apparatus, and computer system

Methods for processing a raw Internet Protocol (IP) packet and corresponding devices are provided. A method is applied on a Broadband Network Gateway (BNG) side, and the method includes that after it is acquired that a Customer Premises Equipment (CPE) goes on line, a public network IP address and a public network identifier range are allocated to the CPE; and after a downlink raw IP packet is received, the packet is forwarded to a corresponding CPE according to a destination IP address of the packet and a route of a public network identifier, another method is applied on a CPE side, and the includes that: a public network IP address and a public network identifier range allocated by a BNG are received; after an uplink raw IP packet transmitted by a user is received, a source IP address in the packet is replaced with the public network IP address, a value of an identifier field in the packet is replaced with a value in the public network identifier range allocated by the BNG, and then the uplink raw IP packet is transmitted to the BNG. The present invention remedies the defect that an existing Network Address Translation (NAT) technology does not support forwarding of a raw IP packet.

Method for processing raw IP packet and device thereof

Provided are a method and apparatus for acquiring a port range resource, and method and apparatus for allocating a port range resource. In the method, a first Router Solicitation (RS) message is sent to a server-end device, wherein information carried in the first RS message includes at least one of an Internet Protocol (IP) address multiplexing request and a port range resource allocation request; and a Router Advertisement (RA) message from the server-end device is received, wherein information carried in the RA message includes: a port range resource allocated according to the IP address multiplexing request and/or according to the port range resource allocation request. By virtue of the technical solution, an Address Plus Port (A+P) technology can be applied to an application scenario where stateless configuration of an Internet Protocol Version 6 (IPv6) address is performed via Neighbour Discovery (ND), thereby expanding the application range of the A+P technology.

Method and apparatus for acquiring port range resource, and method and apparatus for allocating port range resource

A virtual switching method, a related apparatus, and a computer system are provided. The method includes receiving a first message sent by a source node, where the first message is used to request a first virtual machine to perform switching processing on to-be-switched data, where the to-be-switched data is sent from the source node to a target node and at least one of the source node and the target node is a second virtual machine; and determining a second message according to an address of the target node contained in the to-be-switched data and a configured port mapping table, and sending the second message, where the second message is used to instruct the target node to acquire the to-be-switched data from a storage device of a hardware layer.

A double tilt sample holder for in-situ measuring mechanical and electrical properties of microstructures in transmission electron microscope (TEM) is provided. The sample holder includes a home-made hollow sample holder body, a sensor for measuring mechanical/electrical properties, a pressing piece, a sample holder head, a sensor carrier. The sensor for measuring mechanical/electrical properties is fixed on the sensor carrier on the sample holder head by the pressing piece, while the sensor carrier is connected to the sample holder head through a pair of supporting shafts located on sides of the sample holder head. The sensor carrier can tilt within the plane perpendicular to the ample holder head by revolving around the supporting shafts (i.e. tilting along Y axis at an angle of &#xb1;30&#xb0;). The sample holder also allows obtaining mechanical/electrical parameters concurrently.
