With the prohibition of antibiotics in feed, natural plant components as feed additives instead of antibiotics have gradually attracted wide attention and research. Resveratrol, as a natural polyphenol compound with various biological activities, which mainly exists in grapes, Polygonum cuspidatum and other plants, and has antioxidant, anti-inflammatory, antibacterial and anticancer properties. Adding resveratrol to feed can improve the intestinal health of pigs, promote the balance and growth of intestinal microorganisms, and enhance the immunity and disease resistance of pigs. In addition, resveratrol can also improve mitochondrial function and antioxidant capacity of pigs, improve energy metabolism and utilization efficiency of pigs, and improve the growth performance and reproductive performance of pigs. This paper summarizes the application status of resveratrol in pig production, and discusses its potential mechanism, so as to better understand its application effect and potential in pig production and provide reference for future research.

In recent years, lithium metal plays an irreplaceable role in the preparation of all-solid-state lithium batteries and aluminum-lithium alloys; but the cost of lithium metal production is still a problem that needs to be solved by production enterprises. Therefore, this paper optimizes the production process and equipment from the perspective of reducing energy consumption by using Solid Works three-dimensional modeling of the electrolyzer structure as well as ANSYS simulation and simulation software to simulate the thermal field of the electrolyzer and calculations, resulting in the optimal design scheme. Its production electrolysis efficiency can reach 91%, energy consumption is below 35 kWh/kg, chlorine extraction and lithium collection device can run automatically, the concentration of extracted chlorine gas is 90%, the lithium collection efficiency can reach more than 80%, and the amount of lithium is more stable. The equipment can be better put into industrialized production, meet the needs of enterprises to reduce production costs, and promote the development of molten salt electrolysis of lithium metal industry.

This paper reviews the characteristics of membrane distillation technology and the current research progress and hot issues, and compares the latest research progress of membrane distillation technology in terms of membrane material characteristics, membrane wetting and pollution, membrane material modification, research and application in oil and gas field produced water, etc. Membrane distillation technology was found to have great potential for the treatment of oilfield talent effluent, and the energy consumption limitation of membrane distillation technology can be improved by using low-grade thermal energy and coupling other processes. The improvement of membrane materials to obtain high flux and pollution resistant hydrophobic membranes is the key to achieve industrial application of membrane distillation technology.

In order to optimize the energy efficiency and spectral efficiency of decoded-and-forwarded full-duplex relay network in imperfect channel state information, this paper proposed an energy efficiency and spectral efficiency balancing strategy based on this network model. It could replace the non-convex multi-objective optimization problem to a convex single-objective optimization problem by constructing a compromise optimization function of energy efficiency and spectral efficiency. It used derivation method and Lagrange multiplier method to solve the optimal relay transmission power under different compromise factors. The simulation results show that changing the compromise factor can change the energy efficiency and spectral effectiveness of the system and obtain the performance tradeoff of energy efficiency and spectrum effectiveness.
