1Hybrid-Traffic-Detour Based Load Balancing for Onboard Routing in LEO Satellite Networks显示文摘To deal with the dynamic and imbalanced traffic requirements in Low Earth Orbit satellite networks, several distributed load balancing routing schemes have been proposed. However, because of the lack of global view, these schemes may lead to cascading congestion in regions with high volume of traffic. To solve this problem, a Hybrid-Traffic-Detour based Load Balancing Routing(HLBR) scheme is proposed, where a Long-Distance Traffic Detour(LTD) method is devised and coordinates with distributed traffic detour method to perform self-adaptive load balancing. The forwarding path of LTD is acquired by the Circuitous Multipath Calculation(CMC) based on prior geographical information, and activated by the LTDShift-Trigger(LST) through real-time congestion perception. Simulation results show that the HLBR can mitigate cascading congestion and achieve efficient traffic distribution.Peilong Liu Hongyu Chen Songjie Wei Limin Li Zhencai Zhu 2018China Communications2018,15,6:9

3Enhanced multiple anchoring and catalytic conversion of polysulfides by SnO_(2)-decorated MoS_(2) hollow microspheres for high-performance lithium-sulfur batteries显示文摘Lithium-Sulfur(Li-S)batteries are very competitive in energy storage equipment due to their high theoretical capacity and low cost of raw materials.However,the serious polysulfide'shuttle effect',volume expansion effect and slow conversion reaction kinetics of Li-S batteries during the charge/discharge cycle process still need to be resolved urgently.Herein,we prepared a novel sulfur host of SnO_(2)-decorated MoS_(2) hollow microspheres(SnO_(2)-MoS_(2) HMSs).The unique hollow structure provides enough space to accommodate a large amount of sulfur and effectively adapts to its large volume expansion during charge and discharge process.On the other hand,the SnO_(2) nanoparticles that attached to the surface of the MoS_(2) nanosheets will accelerate the catalysis of MoS_(2) and enhance the bonding strength with the polysulfide intermediates through the S-Sn-O chemical bond,which further inhibits the shuttle effect.The newly synthesized SnO_(2)-MoS_(2) HMSs cathode has achieved excellent electrochemical performance.The initial discharge specific capacity of 1326.4 mAh g^(-1) was obtained at 0.2 C,and after 100 cycles,the specific capacity of the SnO_(2)-MoS_(2) HMSs/S cathode only decreased slightly to 1183.8 mAh g^(-1),its capacity retention rate reaching as high as 89.2%.We expect the newly synthesized hollow structured MoS_(2) with SnO_(2) decoration provides a new strategy for the construction of Li-S battery cathode materials.Yun Tian Zhengyu Wei Fan Li Songjie Li Lixiang Shao Mengyuan He Panfei Sun Yuanyuan Li 2022Journal of Materials Science & Technology2022,,5:0

5Review of Research Progress on Concentrated Solar Energy Utilization System显示文摘Solar energy is considered to be one of the most promising renewable and sustainable energy sources.The efficient utilization of solar energy has become a major requirement to build a clean and efficient energy system and achieve the goal of carbon neutrality.The utilization of solar radiation mainly adopts two key technologies:concentrating photovoltaic(PV)and concentrated solar power(CSP).Currently,the cost of CSP with heat storage is about 9c/kWh(same as commercial PV systems)and is expected to drop to 5c/kWh by 2030.From a system level,this paper focuses on analyzing,a system for preparing clean solar fuel based on solar thermal fossil energy,the current mainstream concentrated solar thermal power generation system,the complementary utilization system coupled with multiple energy sources,and the efficient and economical multigeneration system.On the basis of this literature review,the key challenges and future development prospects for the application of concentrating solar energy systems are outlined.A concentrated solar utilization system needs to further improve efficiency and reduce costs in order to expand the scale and promote the market,it has far-reaching significance to achieve the goal of efficient utilization of clean fuel and solar energy.Shunchun Yao Youxing Wei Zhimin Lu Songjie Guo Jinzheng Chen Ziyu Yu 2023Renewables2023,1,4:0
6Analysis of and Theoretical Reflections on China’s“Excessive De-Industrialization”Phenomenon显示文摘Industrialization is a long-term process of spiral transformation and upgrading.In a broad sense,industrialization can be divided into two stages,i.e.shallow industrialization and deep industrialization.The first stage refers to a process of expansive industrialization aiming to increase the proportion of industry,while the second stage refers to a process of contractive industrialization centered on improvements in industrial quality and competitiveness,to which the shallow industrialization is transformed and upgraded.In fact,the industrialization stages divided according to traditional theories,i.e.early stage,middle stage and late stage,are only for achieving the goals of shallow industrialization,instead of ultimately completing the developmental tasks of industrial economy.The transforming and upgrading from shallow industrialization to deep industrialization is an essential stage for a major country to enhance its development quality and competitiveness of industrial economy.So far,China has not fully industrialized.In the context of unbalanced and inadequate industrial development,China has seen a rapid decline in the industrial value-added and employment proportions in recent years,prematurely showing the features of rapid excessive de-industrialization in all respects.China’s current excessive de-industrialization is not only attributed to the impulse of rushing into mass actions in industrial upgrading,but also resulting from the combined effects of multiple factors such as surging factor prices and overcapacity at the current stage,exerting serious negative impacts on China’s economic growth,productivity improvement,development of modern service industry and transfer of agricultural labor force.In a long period of time ahead,considering the need to improve the quality of industrialization and the relationship between industry and services,real economy and virtual economy,the industry dominated by advanced manufacturing industry is still China’s major impetus for driving the medium–high rate of sustained and stable economic growth.Advancing deep industrialization remains a long and arduous task.Therefore,it is required to get rid of the misunderstanding caused by traditional theories and thinking,reconsider the importance of industrialization,implement the strategy of deep industrialization and prevent excessive de-industrialization.The specific measures include:expedite the promotion of deep industrialization in the developed regions of Eastern China,build a group of advanced manufacturing bases in Central and Western China and facilitate an in-depth integrated development of advanced manufacturing industry and modern service industry.WEI Houkai WANG Songji 2019Chinese Journal of Urban and Environmental Studies2019,7,4:0

[Methods] Microscopic identification and thin layer chromatography were used to identify and determine the moisture, total ash and extract contents. [Results] According to the microscopic results, the stem transection is round and has five longitudinal edges at which the cell wall is obviously thickened. Bristles can be observed. A series of collenchyma cells are arranged closely inside the epidermis. There are several rows of parenchyma cells. The vascular bundles are of different sizes;and the ray part is wide, and at the junction of the ray and the cortex, there are often scattered secretory cells. The center is a broad medulla.

The epidermal cells are in the shape of an elongated spindle, in a mosaic arrangement, and the cell wall is slightly thickened. From the thin layer identification chromatograms of tested L. bulbifera, it can be seen that spots were observed at the same positions as the control medicinal material, and the durability of the method was good. The extract content should not be less than 12.00% by hot extraction with water as solvent, and not be less than 3.00% by cold extraction with ethanol as solvent. The moisture content should not be more than 16.50%. The total ash content should not be more than 14.00%. The acid-insoluble ash content should not be more than 2.50%. [Conclusions] The microscopic identification results are reliable and can be used as the identification basis of L. bulbifera. The thin layer identification method and the test results can provide a basis for quality control of L. bulbifera.Wei WEI Huagang LIU Songji WEI Zhonghua DAI Haicheng WEN Chao ZENG 2020Agricultural Biotechnology2020,9,1:0
