The present disclosure relates to an aluminum alloy material, and specifically to a weldable in-situ nano-strengthened rare-earth metal (REM)-containing aluminum alloy with high strength and toughness and a preparation method thereof. In the present disclosure, in-situ nano-ceramic particles and REMs simultaneously introduced into an Al—Zn—Mg alloy can effectively refine the grains and significantly improve the strength and toughness of the alloy; and REM-containing nano-precipitated phases and in-situ nanoparticles distributed in the grains or at grain boundaries can also significantly increase a recrystallization temperature of the alloy, effectively inhibit the dynamic recovery, reduce the re-dissolution of alloying elements, and improve the weldability of the alloy.

The present invention relates to an aluminum matrix composite (AMC), and particularly to a method and apparatus for preparing an AMC with a high strength, a high toughness, and a high neutron absorption. The present invention combines a high-neutron-absorption and highly stable micro-BC extrinsic reinforcement with an in-situ nano-reinforcement containing elements B, Cd, and Hf and having high neutron capture ability, achieves efficient absorption of neutrons by using the large cross-sectional area of the micro-reinforcement, achieves effective capture of rays penetrating gaps of the micro-reinforcement by means of the highly dispersed in-situ nano-reinforcement, and significantly improves the toughness of the composite material by means of the high-dispersion toughening effect of the nano-reinforcement, obtaining a particle-reinforced aluminum matrix composite (PAMC) having high toughness and high neutron absorption.

Disclosed are a pulverized coal preprocessing method and a pulverized coal gasifying method. The pulverized coal preprocessing method comprises the following steps: (1) performing pore broadening on pulverized coal to obtain preprocessed pulverized coal; (2) loading alkali metal ions into the preprocessed pulverized coal under an ion exchange condition to obtain alkali metal loaded pulverized coal. The method further comprises loading a chrome complex into the alkali metal loaded pulverized coal obtained in described step (2). In gasification, the pulverized coal loaded with alkali metal potassium and chrome catalysts obtained by the method has the advantages of high sulphur removal rate, high carbon conversion rate, short gasifying reaction time and high methane production.

Methods, computer program products, and systems are presented. The method computer program products, and systems can include, for instance: receiving, by a Network Virtualization Edge (NVE) of a first virtual network (VN), a multicast packet from a virtual machine (VM) of the first virtual network (VN); determining, by the NVE, whether the NVE currently supports forwarding the multicast packet to a second NVE of a second virtual network (VN), the second virtual network (VN) being logically separated from the first virtual network (VN); responsively to determining that the NVE currently supports forwarding the multicast packet to a second NVE of a second virtual network (VN) forwarding, by the NVE, the multicast packet to the second NVE.
