| 1 | K-bentonite beds and high-resolution integrated strati- graphy of the uppermost Ordovician Wufeng and the lowest Silurian Longmaxi formations in South China显示文摘More than 20 K-bentonite beds were discovered from the Wufeng Formation and the lowest Longmaxi Formation in two sections, both adjacent to the Ordovician-Silurian (O-S) bound-ary and located in Tongzi, Guizhou Province and Yichang, Hubei Province, some 500 km apart from each other in South China. This indicates that many volcanic eruptions occurred near the southeast margin of the Yangtze Platform between the latest Ordovician and the earliest Silurian. Mainly through biostratigraphic and sequence stratigraphic studies, it was found that almost all these far-apart K-bentonite beds may be correlated with each other. This is the first time that a succession of volcanic ash deposits with high potential of correlation was discovered within a strata interval on the main platforms of China. Therefore, these K-bentonite beds may afford ex-cellent event-marker beds helpful to high-resolution research in integrated stratigraphy as well as other lines of research on the O-S boundary in South China. | 苏文博 何龙清 王永标 龚淑云 周湖云 | 2003 | Science China Earth Sciences2003，46，11： | 39 |
| 2 | Coordinated optimal dispatch and market equilibrium of integrated electric power and natural gas networks with P2G embedded显示文摘As power to gas(P2 G) technology gradually matures, the coupling between electricity networks and natural gas networks should ideally evolve synergistically.With the intent of characterizing market behaviors of integrated electric power and natural gas networks(IPGNs)with P2 G facilities, this paper establishes a steady-state model of P2 G and constructs optimal dispatch models of an electricity network and a natural gas network separately. In addition, a concept of slack energy flow(SEF) is proposed as a tool for coordinated optimal dispatch between the two networks. To study how the market pricing mechanism affects coordinated optimal dispatch in an IPGN, a market equilibrium-solving model for an IPGN is constructed according to game theory, with a solution based on the Nikaido-Isoda function. Case studies are conducted on a joint model that combines the modified IEEE 118-node electricity network and the Belgian 20-node gas network.The results show that if the game between an electric power company and a natural gas company reaches market equilibrium, not only can both companies maximize their profits, but also the coordinated operation of the coupling units, i.e., gas turbines and P2 G facilities, will contribute more to renewable energy utilization and carbon emission reduction. | Zexing CHEN Yongjun ZHANG Tianyao JI Zexiang CAI Licheng LI Zhiheng XU | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，3： | 37 |
| 3 | Optimal operation of electricity, natural gas and heat systems considering integrated demand responses and diversified storage devices显示文摘In recent years, the increasing penetration level of renewable generation and combined heat and power(CHP) technology in power systems is leading to significant changes in energy production and consumption patterns. As a result, the integrated planning and optimal operation of a multi-carrier energy(MCE) system have aroused widespread concern for reasonable utilization of multiple energy resources and efficient accommodation of renewable energy sources. In this context, an integrated demand response(IDR) scheme is designed to coordinate the operation of power to gas(P2 G) devices, heat pumps,diversified storage devices and flexible loads within an extended modeling framework of energy hubs. Subsequently, the optimal dispatch of interconnected electricity,natural gas and heat systems is implemented considering the interactions among multiple energy carriers by utilizing the bi-level optimization method. Finally, the proposed method is demonstrated with a 4-bus multi-energy systemand a larger test case comprised of a revised IEEE 118-bus power system and a 20-bus Belgian natural gas system. | Linna NI Weijia LIU Fushuan WEN Yusheng XUE Zhaoyang DONG Yu ZHENG Rui ZHANG | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，3： | 30 |

| 5 | Resilient PNT Concept Frame显示文摘The concept of resilient positioning, navigation and timing (PNT) is described. The definition of resilient PNT is given, the relationship between integrated (or comprehensive) PNT and resilient PNT is analyzed, and it is pointed out that the integrated PNT is the foundation of resilient PNT. Resilient PNT should be divided into resilient sensor integration, resilient functional model and resilient stochastic model. The strategy and principles of resilient integration of sensors are discussed. The resilient integration of sensors should be designed following the optimal, available, compatible and interoperable principles. The concepts of resilient functional model and possible modification strategies of the different functional models are also described. Several possible optimal routes for resilient stochastic model improvements are also set forth. It is pointed out that the optimal improvements of stochastic models for multi PNT sources should follow the same variance scale. At last, the resilient PNT data fusion for state parameters are given based on the resilient functional and stochastic models. | Yuanxi YANG | 2019 | Journal of Geodesy and Geoinformation Science2019，2，3： | 21 |
| 6 | Coordinated Scheduling of Energy Resources for Distributed DHCs in an Integrated Energy Grid显示文摘As more and more distributed renewable energy resources connected to electric power grids,the conventional power system evolves into an integrated energy grid(IEG)in order to satisfy various types of energy demands.This paper proposes a model of the coordinated scheduling of energy resources(CSoERs)for distributed district heating and cooling systems(DHCs)in an IEG.The model takes into consideration both the dispatchable grid-connected generators and distributed renewable energy resources,such as wind energy,solar energy and natural gas.The objective is to minimize the operation costs in the IEG in order to satisfy not only the electrical loads but also the heating loads and cooling loads.Furthermore,an energy storage system for heating loads and cooling loads is also developed in the DHCs to improve the operation reliability in the distributed DHCs.Detailed simulation studies are carried out to verify the effectiveness of the CSoERs under two different operation scenarios:grid-connected scenario and stand-alone scenario.Simulation results demonstrate that the performance of the CSoERs contributes to significant energy saving and reliability operation in both grid-connected scenario and standalone scenario in the IEG. | Qinghua Wu Jiehui Zheng Zhaoxia Jing | 2015 | CSEE Journal of Power and Energy Systems2015，1，1： | 21 |
| 7 | 3D integrated modeling approach to geo-engineering objects of hydraulic and hydroelectric projects显示文摘Aiming at 3D modeling and analyzing problems of hydraulic and hydroelectric en-gineering geology,a complete scheme of solution is presented. The first basis was NURBS-TIN-BRep hybrid data structure. Then,according to the classified thought of the object-oriented technique,the different 3D models of geological and engi-neering objects were realized based on the data structure,including terrain class,strata class,fault class,and limit class;and the modeling mechanism was alterna-tive. Finally,the 3D integrated model was established by Boolean operations be-tween 3D geological objects and engineering objects. On the basis of the 3D model,a series of applied analysis techniques of hydraulic and hydroelectric engineering geology were illustrated. They include the visual modeling of rock-mass quality classification,the arbitrary slicing analysis of the 3D model,the geological analysis of the dam,and underground engineering. They provide powerful theoretical prin-ciples and technical measures for analyzing the geological problems encountered in hydraulic and hydroelectric engineering under complex geological conditions. | ZHONG DengHua LI MingChao LIU Jie | 2007 | Science China(Technological Sciences)2007，50，3： | 20 |

| 9 | Robust optimization for improving resilience of integrated energy systems with electricity and natural gas infrastructures显示文摘The integration of natural gas in electricity network requires a more reliable operating plan for increasing uncertainties in the whole system. In this paper, a threestage robust optimization model is proposed for resilient operation of energy system which integrates electricity and natural gas transmission networks with the objective of minimizing load curtailments caused by attacks. Nonconvex constrains are linearized in order to formulate the dual problem of optimal energy flow. Then, the proposed three-stage problem can be reformulated into a two-stage mixed integer linear program(MILP) and solved by Benders decomposition algorithm. Numerical studies on IEEE30-bus power system with 7-node natural gas network and IEEE 118-bus power system with 14-node natural gas network validate the feasibility of the proposed model for improving resilience of integrated energy system. Energy storage facilities are also considered for the resiliency analysis. | Hao CONG Yang HE Xu WANG Chuanwen JIANG | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，5： | 17 |

| 11 | Advanced technology of high-resolution radar: target detection, tracking, imaging, and recognition显示文摘In recent years, the performances of radar resolution, coverage, and detection accuracy have been significantly improved through the use of ultra-wideband, synthetic aperture and digital signal processing technologies. High-resolution radars(HRRs) utilize wideband signals and synthetic apertures to enhance the range and angular resolutions of tracking, respectively. They also generate one-, two-, and even threedimensional high-resolution images containing the feature information of targets, from which the targets can be precisely classified and identified. Advanced signal processing algorithms in HRRs obtain important information such as range-Doppler imaging, phase-derived ranging, and micro-motion features. However, the advantages and applications of HRRs are restricted by factors such as the reduced signal-to-noise ratio(SNR)of multi-scatter point targets, decreased tracking accuracy of multi-scatter point targets, high demands of motion compensation, and low sensitivity of the target attitude. Focusing on these problems, this paper systematically introduces the novel technologies of HRRs and discusses the issues and solutions relevant to detection, tracking, imaging, and recognition. Finally, it reviews the latest progress and representative results of HRR-based research, and suggests the future development of HRRs. | Teng LONG Zhennan LIANG Quanhua LIU | 2019 | Science China(Information Sciences)2019，62，4： | 17 |
| 12 | Long-term system load forecasting based on data-driven linear clustering method显示文摘In this paper, a data-driven linear clustering(DLC) method is proposed to solve the long-term system load forecasting problem caused by load fluctuation in some developed cities. A large substation load dataset with annual interval is utilized and firstly preprocessed by the proposed linear clustering method to prepare for modelling.Then optimal autoregressive integrated moving average(ARIMA) models are constructed for the sum series of each obtained cluster to forecast their respective future load. Finally, the system load forecasting result is obtained by summing up all the ARIMA forecasts. From error analysis and application results, it is both theoretically and practically proved that the proposed DLC method can reduce random forecasting errors while guaranteeing modelling accuracy, so that a more stable and precise system load forecasting result can be obtained. | Yiyan LI Dong HAN Zheng YAN | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，2： | 16 |
| 13 | Design of integrated radar and communication system based on MIMO-OFDM waveform显示文摘Orthogonal frequency division multiplexing(OFDM)waveform enables radar and communication functions simultaneously, which encounters low angle resolution and poor data rate for traditional single input single output(SISO) systems. To solve these problems, an integrated radar and communication system(IRCS) with multiple input multiple output(MIMO) OFDM waveform is proposed. The different limitations of radar and communication in designing such a system are investigated. Then, an optimization problem is devised to obtain suitable system parameters, including the number of subcarriers, subcarrier spacing, number of symbols,pulse repetition frequency(PRF) and length of cyclic prefix(CP).Finally, to satisfy the requirements of both radar and communication, the IRCS parameters are derived in three typical cases.Several numerical results are presented to illustrate the demands of radar and communication, inconsistent or consistent, for the IRCS parameters and the superiority of the proposed system. | Yongjun Liu Guisheng Liao Zhiwei Yang Jingwei Xu | 2017 | Journal of Systems Engineering and Electronics2017，28，4： | 16 |

| 15 | Spatial heterogeneity of the driving forces of cropland change in China显示文摘By using digital satellite remote sensing data acquired in 1987―1989 and 1999―2000 and GIS combined with the natural and socio-economic data, this paper drew an integrated zonation of the cropland change and its driving forces in China. The results indicated that the cropland change in the study period was constrained by geographical factors and driven by cli-mate change as well as socio-economic system. Moreover, the regional differences of the drivers for cropland change were significant. In the midwest of China, natural condition changes and geographical background were the main constraints and drivers, while in Eastern China, social and economic changes and economic policies were the main driving forces. The cropland loss was nationwide. The dominant factors to cause this decrease included buildup of developing area to attract foreign capital and technologies, changes of industry structure due to urban in-fluence, the change of employment notions thanks to living standard improvement, rapid ur-banization due to the expansion of cities and towns, the diminished farming net income partly because of the global warming effects, and the rapid economic growth stimulated by the con-venient transportation system. These factors interact and interdepend with each other to cause the cropland loss in China recently. The reasons for the increase of cropland were primarily the cultivation and deforestation by the farmers who want to increase income. This study on the mechnism of LUCC relied on the cropland change integrated classification considering the natural or human factors both inside and outside the region, which provides a new approach to study the integrated regionalization and LUCC mechanism. | LIU Xuhua1,2, WANG Jinfeng1, LIU Mingliang4,1 & MENG Bin1,2,3 1.

| 20 | Treatment of irritable bowel syndrome in China:A review显示文摘Irritable bowel syndrome(IBS)is a common,chronic,functional gastrointestinal disorder with a high incidence rate in the general population,and it is common among the Chinese population.The pathophysiology,etiology and pathogenesis of IBS are poorly understood,with no evidence of inflammatory,anatomic,metabolic,or neoplastic factors to explain the symptoms.Treatment approaches are mainly focused on symptommanagement to maintain everyday functioning and to improve quality of life for patients with IBS.However,prescribed medications often result in significant side effects,and many IBS sufferers(particularly Chinese)do not improve.Instead of taking a variety of conventional medications,many have turned to taking traditional Chinese medicine or integrated Chinese and Western medicine for remedy.A number of clinical trials have shown that Chinese herbal,acupuncture or integrative therapies presented improved treatment outcomes and reduced side effects in IBS patients.The purpose of this review article is to examine the treatment approaches of IBS that have been published in recent years,especially in China,to assess the possible differences in treating IBS between China and other countries.This would provide some useful information of unique treatment approach in clinical practice for physicians in the management of IBS in China,thus offering more treatment options for IBS patients with potentially better treatment outcomes while reducing the medical cost burden. | Chun-Yan Li Shu-Chuen Li | 2015 | World Journal of Gastroenterology2015，21，8： | 12 |
