| 1 | Geochronology and geochemistry of the Fangcheng Neoproterozoic alkali-syenites in East Qinling orogen and its geodynamic implications显示文摘Finding of Neoproterozoic syenites at Fangcheng in the northern Qinling region of the East Qinling orogen provides an important constraint on timing of tectonic transformation to extensional regime. The alkaline pluton consists mainly of nepheline syenite,aegirine syenite,and alkali-feldspar syenite. The syenites are of intermediate (SiO2=54%―62%),rich in alkali (K2O+Na2O=12%―15%),aluminum (Al2O3=16.81%―23.26%) and large ion lithophile elements (LILE),without any obvious Nb,Ta,Zr,and Hf anoma-lies. The Fangcheng syenites are geochemically characterized by relative enrichment of LREE,minor differentiation of HREE,significant negative Eu anomalies (Eu=0.13―0.23),less negative εNd(t) values of -1.37 to -3.90,young Nd model ages of 1364 to 1569 Ma,and high zircon saturation temperatures of 915 to 1044℃. The syenitic magmas probably originated from small proportion melting of upper mantle in an extensional regime of intraplate-anorogenic tectonic setting,and have been slightly contaminated by crustal materials during ascending and/or emplacement. LA-ICP-MS zircon U-Pb dating yields ages of 844.3±1.6 Ma (MSWD=0.86),suggesting that the Fangcheng alkaline syenites formed in the early Neo-proterozoic. They are the oldest Neoproterozoic alkaline rocks ever recognized in the Qinling orogen as well as in South China. This implies that the tectonic regime of the Qinling region would have transformed from post-collisional stretch to intraplate-anorogenic extension no later than 844 Ma. | BAO ZhiWei WANG Qiang BAI GuoDian ZHAO ZhenHua SONG YaoWu LIU XiaoMing | 2008 | Chinese Science Bulletin2008，53，13： | 22 |
| 2 | Agricultural development and human diets in Gouwan site,Xichuan,Henan显示文摘This paper undertook the C and N stable isotopic analysis of human bones unearthed at the Gouwan site in Xichuan,Henan,to reveal the human diets and to explore the lifestyle of humans and the development of rice and millet agriculture.The contribution of rice to human diets was almost equal to that of millet in this site though millet agriculture is the traditional economic model for the middle Yellow River Valley.On the other hand,the comparison of C and N stable isotopes in different cultural periods clearly indicates changes in millet and rice agriculture.Humans mainly depended on agriculture and gathering in the Yangshao Culture I. Millet agriculture,livestock rearing,and fishing were enhanced in the Yangshao Culture II.Millet agriculture and animal husbandry developed steadily in the Yangshao Culture III.After that the mixed rice and millet agriculture developed further.In addition,rice agriculture spread to the north in the climate suitable for cultural exchanges between north and south in the Yangshao Culture phases.In the Qujialing Culture period,under a colder climate,the rice farming was not dominant,though the Qujialing Culture played a key role in the site. | FU QiaoMei JIN SongAn HU YaoWu MA Zhao PAN JianCai WANG ChangSui | 2010 | Chinese Science Bulletin2010，55，7： | 13 |
| 3 | Transition of human diets and agricultural economy in Shenmingpu Site, Henan, from the Warring States to Han Dynasties显示文摘Historical records and archaeological remains indicate that the Chinese agricultural economy changed significantly from the Warring States (475-221 BC) to Han Dynasties (206 BC-220 AD), i.e., from rice-millet based agriculture to rice-millet-wheat based agriculture. However, the variation of human diets and the inner relationship between human diets and the agricultural transition during this period remain poorly understood. In this paper, the C and N stable isotopes from human and animal bones at the Shenmingpu site (SMPS), Xichuan County, Henan Province were analyzed. If some outliers (M34, M36, M102) were excluded, the mean 13C value (( 16.7±0.8)‰, n=15) of humans in Han Dynasties was dramatically lower than that in the Warring States (( 12.7±0.8)‰, n=14), indicating that the cultivation of rice and wheat, especially wheat, had been more widely popularized in Han Dynasties. Meanwhile, the range of 15N values of humans (6.6‰-9.3‰) in Han Dynasties was narrower than that of the Warring States (6.2‰-10.4‰), suggesting that the animal protein resources in human foods during Han Dynasties were more concentrated. The transition of human diets and the close relationship with the change of agricultural economy in SMPS were due to more stable society, the carryout of new agricultural policies, and the emergence of new agricultural tools in Han Dynasties. | HOU LiangLiang WANG Ning Lu Peng HU YaoWu SONG GuoDing WANG ChangSui | 2012 | Science China Earth Sciences2012，55，6： | 10 |
| 4 | Tianshanbeilu and the Isotopic Millet Road: reviewing the late Neolithic/Bronze Age radiation of human millet consumption from north China to Europe显示文摘The westward expansion of human millet consumption from north China has important implications for understanding early interactions between the East and West.However,few studies have focused on the Xinjiang Uyghur Autonomous Region,the vast geographical area directly linking the ancient cultures of the Eurasian Steppe and the Gansu Corridor of China.In this study,we present the largest isotopic investigation of Bronze Age China(n=110)on material from the key site of Tianshanbeilu,in eastern Xinjiang.The large range ofδ13C values(–17.6 to–7.2;–15.5±1.2)provides direct evidence of unique dietary diversity and consumption of significant C4 resources(millets).The highδ15N results(10.3 to 16.7;14.7±0.8)likely reflect sheep/goat and wild game consumption and the arid climate of the Taklamakan Desert.Radiocarbon dates from four individuals indicate Tianshanbeilu was in use between 1940 and1215 cal bc.The Tianshanbeilu results are then analysed with respect to 52 Bronze Age sites from across Eurasia,to investigate the spread and chronology of significant human millet consumption and human migration.This isotopic survey finds novel evidence that the second millennium bc was a dynamic period,with significant dietary interconnectivity occurring between north China,Central Asia and Siberia.Further,we argue that this‘Isotopic Millet Road’extended all the way to the Mediterranean and Central Europe,and conclude that these C4 dietary signatures of millet consumption reflect early links(migration and/or resource transfer)between the Bronze Age inhabitants of modern-day China and Europe. | Tingting Wang Dong Wei Xien Chang Zhiyong Yu Xinyu Zhang Changsui Wang Yaowu Hu Benjamin T.Fuller | 2019 | National Science Review2019，6，5： | 8 |
| 5 | Stable carbon and nitrogen isotope evidence of human and pig diets at the Qinglongquan site,China显示文摘Previous studies on the Rice-Millet(foxtail millet and common millet) Blended Zone in Chinese Neolithic have not clearly addressed such questions as the importance of primitive rice-millet mixed agriculture to human lifestyle and livestock managements within this region,the relationship among the development of the agriculture,paleoenvironment,and cultural interactions,and so on.Here stable carbon and nitrogen isotope analysis of human and pig bones from the Qinglongquan site was conducted,covering two cultural phases,namely the Qujialing Culture(3000 BC to 2600 BC) and the Shijiahe Culture(2600 BC to 2200 BC) .Based on this analysis,we further discussed the diets of ancient humans and pigs in the site,investigated the importance of rice-millet mixed agriculture to human and pig diets,and explored the relationship among the primitive rice agriculture and millet agriculture,cultural interactions,and paleoenvironment.The δ13C values of human bone collagen(-16.7‰ to-12.4‰,averaging-14.6‰±1.3‰,n=24) revealed that both C3 and C4 foods were consumed,probably from the contribution of rice(C3 plant) and millets(C4 plants) due to the coexistence of these crops at this site.In addition,the human mean δ13C value suggested that millet agriculture was only minor in human diets.The human δ15N values(6.6‰to 10.8‰,averaging 9.0‰±1.2‰,n=24) showed that animal resources played a significant role in human diets,and varied greatly.The mean δ13C value of the pigs(-14.3‰±2.5‰,n=13) was quite similar to that of the humans,but the mean δ15N value of the pigs was slightly less(1.3‰) .The similar δ13C and δ15N values between humans and pigs suggested that the pigs consumed a lot of humans'food remains.No correlations of the δ13C and δ15N values between humans and pigs showed that both human and pig diets were based mainly on plant foods,which might be related to highly developed rice-millet mixed agriculture at that time. In comparison with the human and pig diets between the two periods,millet agriculture contributed more than 10%in the Shijiahe Culture,if a simple mixing model was used.This apparent dietary shift matched the climatic variation and agricultural development through the time.In warm and humid climate with the expansion of the Qujialing Culture northwards,rice was widely cultivated.However,when the climate was cold and arid,northern culture was expanding southwards.Thus,millet agriculture became more important. | GUO Yi HU YaoWu ZHU JunYing ZHOU Mi WANG ChangSui Michael P.

| 6 | Low-carbon Operation of Combined Heat and Power Integrated Plants Based on Solar-assisted Carbon Capture显示文摘Accelerating the development of renewable energy and reducing CO_(2)emissions have become a general consensus and concerted action of all countries in the world. The electric power industry, especially thermal power industry, is the main source for fossil energy consumption and CO_(2)emissions. Since solvent-based post-combustion carbon capture technology would bring massive extra energy consumption, the application of solar-assisted carbon capture technology has attracted extensive attention. Due to the important role of coal-fired combined heat and power plants for serving residential and industrial heating districts, in this paper, the low-carbon operation benefits of combined heat and power integrated plants based on solar-assisted carbon capture(CHPIP-SACC) are fully evaluated in heat and power integrated energy system with a high proportion of wind power. Based on the selected integration scheme, a linear operation model of CHPIP-SACC is developed considering energy flow characteristics and thermal coupling interaction of its internal modules. From the perspective of system-level operation optimization, the day-ahead economic dispatch problem based on a mix-integer linear programming model is presented to evaluate the low-carbon benefits of CHPIP-SACC during annual operation simulation. The numerical simulations on a modified IEEE 39-bus system demonstrate the effectiveness of CHPIP-SACC for reducing CO_(2)emissions as well as increasing the downward flexibility. The impact of different solar field areas and unit prices of coal on the low-carbon operation benefits of CHPIP-SACC is studied in the section of sensitivity analysis. | Xusheng Guo Suhua Lou Yaowu Wu Yongcan Wang | 2022 | Journal of Modern Power Systems and Clean Energy2022，10，5： | 5 |
| 7 | Palaeodietary study of Sanxingcun Site,Jintan,Jiangsu显示文摘C and N stable isotope ratios of 19 human bones in Sanxingcun Site, Jintan, Jiangsu Province, were measured to explore the lifestyle and social economic structure. Although the bone collagen degraded to different extents, the atomic ratio of C/N was located in the range of 2.9-3.6, indicating that they were preserved very well. Average δ13C value (20.05±0.21‰), average δ 15N value (9.69 ±0.33‰) and poor positive correlation between each other suggested that rice agriculture was dominant with hunt-ing-fishing supplemented in human lifestyle. Poor negative correlation between δ 15N values and C3 percentages of foods implied relative independence of rice agriculture and hunting-fishing. Compared to Hemudu Site and Qingpu Site, rice agriculture was developed further, but hunting-fishing decreased. The mode for people in Sanxingcun Site to get the meat was still in the initial exploitation. | HU YaoWu WANG GenFu CUI YaPing DONG Yu GUAN Li WANG ChangSui | 2007 | Chinese Science Bulletin2007，52，5： | 4 |
| 8 | Key Factors for Efficient Consumption of Renewable Energy in a Provincial Power Grid in Southern China显示文摘The development of renewable energy sources(RES)is important to promote the energy transition and address climate change.Unlike the centralized RES power plants in the north of China,the distributed RES power plants in the south of China for achieving local consumption have become an effective alternative.However,the differences between RES and hydropower consumption have become obvious in some areas.This paper investigates the key factors affecting the abandonment of RES in the south of China.To alleviate the problem of RES consumption,various measures are discussed from the aspects of evaluating the consumption capacity of power grids at different voltage levels,optimizing demand-side management,flexibly for reforming the peak-shaving power sources of thermal power plants and strengthening inter-provincial transactions.The production simulation is used to validate the analysis and discussion. | Ming Wen Yong Li Xintao Xie Yijia Cao Yaowu Wu Weiyu Wang Li He Yu Cao Binkun Xu Limiao Huang | 2020 | CSEE Journal of Power and Energy Systems2020，6，3： | 3 |
| 9 | A Pilot Study of Trophic Level and Human Origins at the Xiaoshuangqiao Site, China(ca. 1400 BC) Using 8D Values of Collagen显示文摘We present here a pilot study to examine trophic level effects and migration patterns at the middle Shang Dynasty site of Xiaoshuangqiao in Henan Province using δD results combined with δ^(13)C and δ^(15)N values. A total of 33 specimens(17 humans, 7 cattle, 5 pigs, 3 sheep, 1 dog) of bone collagen were isotopically analyzed for δ^(13)C, δ^(15)N, and dD values. A strong positive correlation(R^2 = 0.94)between mean δ^(15)N and δD values of herbivores(cattle and sheep), omnivores(pig), carnivores(dog)and humans was observed. The δD results were found to increase by ~10‰ to 20‰ from herbivores to omnivores to carnivorous, evidence that collagen δD results are a useful indicator for the study of trophic levels and dietary patterns at archaeological sites. The δD results were also used to examine the origins of two different groups of individuals buried at Xiaoshuangqiao. Individuals buried in sacrificial pits of district V had mean δD values(-47.0 ± 2.9‰, n = 11) that were significantly(p =0.049) elevated compared to the people buried in the stratigraphy of district IX(-51.3 ± 3.3‰, n = 3),indicating that they were ingesting water from different locations. In addition, the D values of the people buried in the stratigraphy were similar to the pigs(-54.5 ± 4.2‰, n = 5) at Xiaoshuangqiao,suggesting that they were most probably of the local population, and that the individuals buried in the sacrificial pits were most possibly from the coast and prisoners of the Dongyi('东夷')people. Thus,δD results have the potential to examine human origins and migration patterns and should be increasingly used in conjunction with δ^(13)C and δ^(15)N values at archaeological sites. | WANG Ning LI Suting HU Yaowu SONG Guoding | 2017 | Acta Geologica Sinica(English Edition)2017，91，5： | 2 |
| 10 | The subsistence patterns of the Shengedaliang site(-4,000 yr BP)revealed by stable carbon and nitrogen isotopes in northern Shaanxi,China显示文摘In order to explore subsistence patterns in northern Shaanxi Province around 4,000 yr BP,28 human and 24 animal bones from the Shengedaliang site were sampled for stable carbon and nitrogen isotope ratio analysis.The results show that most people primarily subsisted on C_4 resources,e.g.millet and millet-related animal products,despite the fact that there was some intake of C_3 plants by some individuals.Stable nitrogen isotope values indicate that there were differences in meat consumption between individuals at the site.Pigs were mainly foddered with millet and millet byproducts,as well as some cattle,according to their highδ^(13)C values.However,most cattle and the sheep/goats consumed wild C_3 plants at Shengedaliang.Our above findings indicates that subsistence patterns in northern Shaanxi around 4,000 yr BP were characterized by millet farming,while the grassland animal husbandry,e.g.cattle and sheep/goats raising,displayed very little contribution to local economy.The intensive millet farming in northern Shaanxi provided enough food for population growth,ensured the accumulation of wealth,and consequently accelerated social differentiation and complexity. | CHEN XiangLong GUO XiaoNing WANG WeiLin HU SongMei YANG MiaoMiao WU Yan HU YaoWu | 2017 | Science China Earth Sciences2017，60，2： | 2 |

| 20 | Effect of WO3 on Hydration Resistance of CaO Aggregate Prepared by Thermal Decomposition显示文摘The application of CaO refractories was limited due to its poor hydration resistance.Introducing appropriate additive is an effective way to improve its hydration resistance.Additive WO3 was introduced in the preparation of CaO aggregates using calcination method in this study.The introduction of WO3 decreased the apparent porosity of CaO aggregates and promoted the grain growth of CaO by the formation of liquid at high temperatures.The average grain size of the specimens with 0.4 mass%WO3 and treated at 1550℃was increased to 51.6μm comparing to 33.5μm that without WO3 additive.As a result,the hydration resistance of CaO aggregate was significantly improved.Besides,WO3 sublimate easily,therefore,less WO3 was remained after the heat treatment.The further increase of WO3 addition had little effect on the hydration resistance of CaO specimens. | ZHANG Tao WEI Yaowu LI Nan LI Bingrong WANG Jinhu | 2020 | China's Refractories2020，29，3： | 1 |
