The invention discloses a self-adaptive load balancing method for the parallelization of spatial computation, comprising the steps of: parallelizing spatial computation; in the process of computation, dynamically adjusting a dividing line according to load change conditions among a plurality of processors in order to reach new balance; and accelerating spatial re-division by compressing or extending the divided word spaces in a manner of grouping. During the parallelization of spatial computation, each processor is responsible for computing one divided subspace, and the computation quantity derives from the number and the complexity of the computed objects in the space; the computation complexities of the computed objects are set to be same, thus the computation quantity is represented bythe number of the objects; in the process of computation, when moving in the space, the computed objects are considered to move from the space for which one processor is responsible to the space for which another processor is responsible, which results in the change of computation load. The self-adaptive load balancing method provided by the invention can rapidly balance the loads among a plurality of processors responsible for the computation of subspaces, and simultaneously, small communication loads are realized among balanced hosts.

The invention discloses a preparation method of a hemostatic sponge. The steps are as follows: (1) disperse oxidized cellulose powder in water to prepare an oxidized cellulose dispersion with a mass fraction of 0.1wt% to 2.0wt%, and then oxidize the cellulose The dispersion liquid is subjected to high-pressure homogenization treatment to obtain a nano-oxidized cellulose suspension; (2) inject the nano-oxidized cellulose suspension into a mold, and perform 1 to 7 freeze-thaw cycles to obtain a nano-cellulose hydrogel. The cellulose hydrogel is freeze-shaped, and then freeze-dried to obtain a hemostatic sponge; wherein, one freeze-thaw process is: freezing at -40°C to -18°C for 8-16 hours, and then thawing at 4-25°C for 8-16 hours. The invention also provides a hemostatic sponge prepared by the preparation method. The hemostatic sponge has high carboxyl content, high porosity and water absorption capacity, and can quickly absorb excess blood on the wound surface to achieve the purpose of effective hemostasis.

Disclosed in an embodiment of the present invention is a load balancing method applied in a load balancing apparatus. The method comprises: when a service data volume from a first virtual node is determined to have reached an alert threshold, determining a virtual node having a same type as a second virtual node, wherein the second virtual node is configured to process the service data from the first virtual node; after setting the virtual node having the same type as the second virtual node to the standby state, when the service data volume is determined to have reached a fault threshold, adding forwarding configuration information between the first virtual node and the virtual node in the standby state, and setting the virtual node in the standby state to a loading state in order to share a load of the second virtual node, the alert threshold being less than the fault threshold. Also disclosed in the embodiment of the present invention is a load balancing apparatus.

The invention discloses a method for realizing horizontal expansion of a one-to-one network address translation gateway, which relates to the technical field of gateway translation; two ends of a NAT gateway are configured: the inner side and the outer side of the NAT gateway are respectively connected to two switches through two network interfaces, and the network interfaces are bonded , the switch on the same side is bonded, and the NAT gateway is configured with openflow rules; the switch and the NAT gateway conduct an OSPF session through the OSPF routing protocol. The rule modifies the source IP address to the IP address of the public network, and guides the traffic to the external switch. In the direction of the return of the traffic, the external switch sends the traffic to a NAT gateway according to the IP quintuple packet. The NAT gateway will Change the target IP address to a public IP address, and send the traffic to the internal switch.

The invention discloses a self-assembled amino acid derivative functionalized magnetic-carbon nanotube composite material and its preparation method and application. The magnetic Fe is prepared by a one-step solvothermal reduction method. 3 o 4 ‑Multi-walled carbon nanotube composites utilizing magnetic Fe 3 o 4 Hydrophobic interaction of / MWCNTs composite material, N-hexadecyl-L-hydroxyproline self-assembled on the surface of carbon nanotubes to obtain a stable complex, this material was used as a chiral adsorbent to resolve amino acid enantiomers isomers to test their chiral resolution performance. The present invention uses magnetic nanomaterials as chiral selector carriers, combined with self-assembly technology as a fixed method to prepare chiral recognition materials, which is expected to improve the stability of the chiral stationary phase and the lack of loading capacity, and realize rapid screening of chiral selectors. Efficient, high-capacity chiral separations.
