Abstract: The present application provides a high-gravity device for generating nano/micron bubble and a reaction system. In the device, the liquid phase is continuous phase and the gas phase is dispersed phase. A gas enters the interior of the device from a hollow shaft, and the gas is subjected to primary shearing under a shearing effect of aerating micropores to form bubbles; then, the bubbles rapidly disengage from the surface of a rotating shaft under the effect of the rotating shaft rotating at a high speed, and are subjected to secondary shearing under the high-gravity environment with the strong shearing force formed by the rotating shaft to form nano/micron bubbles. The device has the advantages of fastness, stability, and small average particle size. The average particle size of the formed nano/micron bubbles is between 800 nanometers and 50 microns, and the average particle size of the bubbles can be regulated in a range by adjusting the rotating speed of the rotating shaft.

Filter rules generated from the ACL are stored in a first memory store in a switch and NAT rules generated from the NAT mappings are stored in a second memory store separate from the first memory store. When a packet matches one of the filter rules a tag that identifies the ACL is associated with the packet. When the tagged packet matches one of the NAT rules, the packet is translated according to the matched NAT rule.

After validation, the transaction is stored into blockchain as an electronic certification of contract execution.
