本文根据1949年中华人民共和国成立至1956年基本完成社会主义改造时期的有关历史资料,以基础教育(中小学)教科书的编写、编辑、出版、印制、发行等管理事项为内容,通过史料整理分析梳理了新中国基础教育教科书出版经营的独特模式——"租型"经营模式的历史源头与演变过程。发现中小学教材的"租型"经营模式是老一辈出版家根据在国民党统治区和解放区的出版经营实践,基于当时中国一穷二白的经济现状和新中国建设社会主义的愿景,将马克思主义政治经济学与中国实际相结合创造出的、新中国中小学教材出版经营的优秀经济模式。

Microstructure and Properties of Fe-Based Coating on Column Surface Formed by High Frequency Induction Cladding

第43届中国控制会议

作者： Baojia Cui huilong yang Xiaoyuan Luo Xinyu Wang Xiaolei Li School of Electrical Engineering Yanshan University

Meeting low-carbon objectives requires a heightened emphasis on adopting novel energy technologies. Among these,microgrid technology has gained considerable prominence for integrating renewable energy sources into daily life. This paper introduces a novel multi-objective optimal dispatching model tailored for grid-connected microgrids. Initially, a comprehensive microgrid system incorporating photovoltaic(PV), wind turbine(WT), diesel generator(DE), micro gas turbine(MT), and energy storage device(ESS) is thoroughly examined. Subsequently, this paper innovatively applies the Multi-Objective Artificial Hummingbird Optimisation Algorithm(MOAHA) to the field of microgrids, based on which a hybrid microgrid system model is established and processed to solve the optimal scheduling problem of a hybrid microgrid system. Notably, by comparing with the Multi-Objective Particle Swarm Algorithm(MOPSO), the simulation verifies that the proposed optimisation scheme can significantly reduce the operating costs and pollutant emissions, while effectively meeting the crucial environmental and economic objectives of microgrids.

Journal of Surface Engineered Materials and Advanced Technology 2012年第1期2卷 40-43页

作者： huilong yang Yufu Sun Jingjie Shen Sumeng Hu Qing Zhao Xiangcai Jia Jingchao Zhang 不详

The Fe-based coating was produced on the surface of the column substrate with a Al2O3 cylindrical sleeve by high frequency induction cladding, microstructure of the coating was investigated with scanning electron microscope (SEM), the crystal structure was characterized by X-ray diffractometer (XRD), the microhardness and wear resisitance of the coating were evaluated. The results show that a metallurgical bond between coating and substrate was obtained during the rapid solidification, the phases of the coating were composed of austenite and the eutectic of γ-Fe + (Cr, Fe)7(C, B)3. Compared with the substrate, the microhardness and wear resistance of the coating improved apparently, solid-solution strengthening and second-phase particle hardening led to these results.

Fairness Performance Analysis:HSTCP/Drop Tail vs. HSTCP/AQM

第二十四届中国控制会议

作者： Long Chengnian, yang huilong, Zhao Bin, Guan Xinping (Department of Electrical Engineering, Yanshan University, Qinhuangdao, 066004)

＜正＞ A new active queue management （AQM） based on dead-beat control theory, called DBC. is proposed in this paper. DBC can increase link utilization and decrease the packet loss rate through tracking the reference queue length promptly especially under networks with large delay, and shows a satisfactory performance under dynamic traffic load. A simple stability analysis based on control theory was given in this paper. Finally we illustrate that DBC outperforms the recently proposed AQM algorithms in terms of link utilization, packet loss and robust performance through extensive simulation.

Fairness Performance Analysis:HSTCP/Drop Tail vs. HSTCP/AQM

Advances in Graphene‑Based Electrode for Triboelectric Nanogenerator

第25届中国控制会议

作者： Long Chengnian, yang huilong, Liu Zhixin, Guan Xinping Institute of Electrical Engineering, Yanshan University, Qinhuangdao, 066004

＜正＞In this letter we present fairness performance comparison between HSTCP with DropTail router and that with AQM router. With the assumption of synchronous feedback, the RTT unfairness of TCP AIMD congestion avoidance algorithm is obvious. However, the RTT unfairness may be exponential increased in HSTCP with DropTail router. By constructing the duality model of HSTCP with AQM router, we highlight that AQM can improve the fairness performance of HSTCP. Our quantitative result shows that the unfairness of HSTCP/AQM is inverse proportional to its RTT. The insight is validated by NS2 simulation.

四川省生产用水量占总用水量比重在80%以上,生产用水变化趋势直接决定总用水量变化趋势。文章基于扩展的Kaya恒等式将四川省生产用水驱动效应分解为经济水平、产业结构、用水水平和人口规模4类,采用LMDI模型量化不同因素的驱动效应,并利用自然间断点分级法对不同因子驱动效应进行空间分析。结果表明:经济水平效应和人口规模效应是导致四川省生产用水量增加的因素,经济水平效应对生产用水量增加的贡献程度大于人口规模效应贡献程度;产业结构效应和用水水平效应是导致四川省生产用水量降低的因素,用水水平效应对生产用水量减少的贡献程度大于产业结构效应贡献程度;影响四川省生产用水量变化的各驱动效应的强弱空间分布与区域经济水平和人口规模等因素密切相关,强、中驱动主要分布在成都平原经济区,弱驱动分区主要分布在川西北生态经济区和川东北经济区。分析结果对正确理解四川省经济社会发展与生产用水变化之间的关系具有一定参考意义。
