| 1 | Strontium and boron isotopic constraint on the marine origin of the Khammuane potash deposits in southeastern Laos显示文摘Since 2006,we have conducted a geological exploration of the Khammuane area in southeastern Laos.Several thick sequences of potash deposits containing sylvite and carnallite were discovered from drilling Paleocene strata of the Thangon Formation(E1tg).To constrain the origin of the brine that formed thick sequences of salt mineral deposits,we measured the strontium and boron isotope composition of some salt minerals in the potash deposit.Boron isotope composition of halite-and potash-associated minerals in the Khammuane potash deposit varied from 19.91%to 31.01‰,which differs significantly from continental evaporates(-6.83‰--5.79‰)but is very close to that of salts precipitated from evapo-concentrated seawater(10‰-36‰).The 87Sr/86Sr ratios(0.707542 to 0.709461)of salts were also close to the values of Paleocene seawater(0.70772 to 0.707830).The content of Br-(0.01%-0.25%)and Br×103/Cl ratios(0.10-0.52)of halite were>10 times higher than that of common continental salts.These characteristics indicate clearly that the Laos potash deposits were deposited from seawater.The small variation in boron and strontium isotopes in all salt sedimentary sequences(gypsum-halite-potash-halite)also suggests that the recharge source should be stable and the effects of other continental water mixing are negligible.Large-scale potash deposits are commonly precipitated from seawater.Hence,the results of recent regional drilling work and geochemical research suggest extensive potash resources could occur in the Thangon Formation of southeastern Laos. | TAN HongBing MA HaiZhou LI BinKai ZHANG XiYing XIAO YingKai | 2010 | Chinese Science Bulletin2010，55，27： | 37 |
| 2 | The growth mechanism of the basic magnesium chloride whisker显示文摘Based on the theoretical model of anion coordination polyhedron growth units, the growth mechanism of the basic magnesium chloride whisker was discussed in this paper.It was found that the basic magnesium chloride whisker habits were related to the different environments in which anion coordination polyhedra grew. The growth units of basic magnesium chloride whiskers are [Mg - (OH) 4]2 -and [Mg - Cl 4]2 -. The growth process is the incorporation process of growth units. Growth units will have different incorporations and orientations caused by different system characters or heating. Furthermore, the formation mechanism of basic magnesium chloride whiskers was also interpreted using anion coordination polyhedron growth units. | WU JianSong XIAO YingKai SU JingYun DENG TingTing FENG JieRong MO YuYing ZENG Mei | 2011 | Science China(Technological Sciences)2011，54，3： | 18 |
| 3 | The growth mechanism of hydrotalcite crystal显示文摘From the point of growth units, the growth mechanism of hydrotalcite (HT) crystal is investigated in this paper. Results show that the growth morphology of HT is consistent with the model of anion coordination polyhedron growth units. The Raman shift of growth solutions of HT, Cu-HTlc, and Cu-Zn-HTlc are monitored using Raman spectroscopy. In the experiment, the growth units of Mg-Al-hydrotalcite are [Mg-(OH)6]4- and [Al-(OH)6]3-, and the growth units of Cu-Htlc and Cu-Zn-HTlc are [Mg-(OH)6]4- and [Al-(OH)6]3-, respectively. The growth process of hydrotalcite is as follows: growth units first incorpo- rate into metal layers, then metal layers adsorb An- and H2O, and the growth units incorporate into layer compounds according to this rule. Growth units will have different incorporations and growth morphologies caused by different growth surroundings. Furthermore, the reason why Cu-HTlc is difficult to synthesize is also interpreted in this paper. | WU JianSong XIAO YingKai WAN JianYu WEN LiRong | 2012 | Science China(Technological Sciences)2012，55，4： | 15 |
| 4 | In situ boron isotope measurements of natural geological materials by LA-MC-ICP-MS显示文摘There are two main methods to determine boron isotopic composition.One is the solution method,in which boron is purified after the samples are dissolved in solution and the boron isotope ratios are determined by thermal ionization mass spectrometry(P-TIMS and N-TIMS) or multicollector inductively coupled plasma mass spectrometry(MC-ICP-MS).The other is an in-situ analysis method,in which the in-situ boron isotopic ratios in minerals are analyzed directly using secondary ion mass spectrometry(SIMS) or laser ablation multicollector inductively coupled plasma mass spectrometry(LA-MC-ICP-MS).In the in-situ analysis method for boron isotopes,the multifarious chemical purification and separation processes of the solution method are avoided,with increased work efficiency.In addition,the microzones and microbeddings of minerals can be analyzed in-situ to reveal the fine processes and conditions of mineral formation.In this study,using the standard-sample-bracketing(SSB) method,mass bias of the instrument and the fractionation of isotopes were calibrated,and the in-situ determination method of LA-MC-ICP-MS for boron isotopes was established.Through detailed analyses on a series of boron isotope standards and samples,a matrix effect was assessed but not detected,and the analysis results were in accordance with the formerly reported values or P-TIMS determined values,within the error range.The analytical results for IAEA B4 and IMR RB1 with relatively high boron contents were δ 11B =-(8.36±0.58)‰(2σ,n=50) and δ 11B =-(12.96±0.97)‰(2σ,n=57),respectively;the analytical result for IAEA B6 with rela-tively low boron content was δ 11B =-(3.29±1.12)‰(2σ,n=35).In-situ measurements for B isotopes were performed on geo-logical samples such as tourmaline,ulexite,ludwigite,inyoite and ascharite,with the results consistent with those determined by P-TIMS,within the error range. | HOU KeJun LI YanHe XIAO YingKai LIU Feng TIAN YouRong | 2010 | Chinese Science Bulletin2010，55，29： | 13 |
| 5 | Content analysis of systematic reviews on effectiveness ofTraditional Chinese Medicine显示文摘OBJECTIVE:To evaluate evidence for the efficacy of Traditional Chinese Medicine(TCM) in systematic reviews.METHODS:Chinese(TCM Periodical Literature Database,Chinese Biological Medicine database,Chinese Medical Current Contents,China Hospital Knowledge Database journal fulltext database,Virtual Machining and Inspection System,and Wanfang) and English(Cochrane Database of Systematic Reviews,PubMed and Embase) databases were searched.RESULTS:Three thousand,nine hundred and fifty-five articles were initially identified,606 of which met the inclusion criteria,including 251 in English(83 from the Cochrane Database) and 355 in Chinese.The number of articles published each year increased between 1989 and 2009.Cardiocerebrovascular disease was the most studied target disease.Intervention measures included TCM preparations(177 articles),acupuncture(133 articles) and combinations of TCM and Western Medicine(38 articles).Control measures included positive medical(177 articles),basic treatment(100 articles),placebo(219 articles),and blank and mutual(107 articles).All articles included at least one reference;the greatest number was 268.Six of 10 articles with high quality references demonstrated curative effectsagainst target diseases including upper respiratory tract infection,dementia and depression.Interventions that were not recommended were tripterygium for rheumatoid arthritis and TCM syndrome differentiation for pediatric nocturia.In 10.4% of the studies,the authors concluded that the intervention had a curative effect.The assessors agreed with the authors' conclusions in 88.32% of cases,but rejected 8.94%(54 articles).CONCLUSION:1) Training in systematic review methods,including topic selection,study design,methods and technology,should be improved.2) Upper respiratory tract infection,dementia and depression may become the predominant diseases treated by TCM,and the corresponding interventions could be developed into practical applications.3) Use of non-recommended interventions should be controlled,and there should be more research on side effects. | Junwen Wang Meng Cui Hongguan Jiao Yuanyuan Tong Jun Xu Yingkai Zhao Mei Han Jianping Liu | 2013 | Journal of Traditional Chinese Medicine2013，33，2： | 7 |

| 7 | Boron isotopic fractionation during incorporation of boron into Mg(OH)_2显示文摘Experiments of boron incorporated into Mg(OH)2 from magnesium-free synthetic seawater were carried out at various pH values, in order to investigate the adsorption species and the variation of isotopic fractionation of boron on Mg(OH)2. The results showed that the incorporation of boron into Mg(OH)2 was very rapid and reached the equilibrium after 4 h. The [B]s and the partition coefficient Kd between Mg(OH)2 and final solution decreased with the increasing pH. The maximum values of [B]s and Kd were much higher than that of boron adsorbed on metal oxide or clay minerals, indicating that the incorporation capability of boron into Mg(OH)2 was very strong. When the adsorption reached the equilibrium, the δ 11Bfsw was lower than δ 11Bisw. The boron isotopic fractionation αs-fsw was between 1.0186 and 1.0220 with an average of 1.0203. All these indicated that 11B incorporated into Mg(OH)2 preferentially due to B(OH)3 incorporation into Mg(OH)2 preferentially. The deposition reaction of B(OH)3 with Mg(OH)2 was the direct reason for B(OH)3 incorporation into Mg(OH)2. During the boron incorporation into Mg(OH)2, the isotopic fractionation characteristic of boron was decided by the simultaneous existence of adsorption of boron on Mg(OH)2 and the deposition reaction of H3BO3 with Mg(OH)2. Different from the fact that only B(OH)4-species incorporated into bio-carbonate, B(OH)3 and B(OH)4 incorporated into Mg(OH)2 simultaneously, and B(OH)3 incorporated into it preferentially. The lower pH is, the more incorporated fraction of B(OH)3 will be. Mg(OH)2 exists widely in madrepore, which influences the quantitative correspondence of the boron isotopic composition δ 11Bcarb of corals on the pH of the seawater badly, and brings serious uncertainty to the δ 11Bcarb as the indicator of the ancient seawater pH. | XIAO Jun XIAO YingKai LIU CongQiang ZHAO ZhiQi HE MaoYong LIANG ChongShan | 2009 | Chinese Science Bulletin2009，54，17： | 7 |
| 8 | Stable isotope fractionation of chlorine during evaporation of brine from a saline lake显示文摘Brine from the saline Qarhan Lake was evaporated at 28±2°C in a clean environment.Two groups of experiments were conducted;one with complete separation of precipitate and brine at different stages of evaporation,and the other with continuous precipitation during the evaporation.Seventy-nine precipitate and brine samples were collected during the experiments,and the δ37 Cl values were determined using an improved thermal ionization mass spectrometry procedure for precise measurement of chlorine isotopes based on Cs2Cl+ ions.Based on the concentrations of Na+,K+,and Mg2+,evaporation was divided into three main precipitation stages as follows:halite dominant,carnallite dominant,and bischofite dominant.The δ37 Clsolid and δ37 Clliquid values of the precipitate and coexisting brine samples at different stages showed the following characteristics.The precipitates were enriched with 37 Cl relative to the coexisting brine samples,and the δ37 Cl of both the precipitate and brine samples decreased gradually during evaporation.The fractionation factors(αh) between halite and brine were the highest,followed by that(αc) between carnallite and brine,and then that(αb) between bischofite and brine.The αc and αb values of less than one,which indicate the precipitate is enriched in 35 Cl,were found when the evaporation process entered a new stage.However,the δ37 Cl values of carnallite,bischofite,and the coexisting brine samples decreased during evaporation.The residual brine is a 35 Cl reservoir.The experimental phenomena were consistent with the δ37 Cl values in saline deposits in the literature.δ37 Cl can be used as an indicator of brine evaporation processes,which is important in the exploration of sylvinite deposits. | LUO ChongGuang XIAO YingKai MA HaiZhou MA YunQi ZHANG YanLing HE MaoYong | 2012 | Chinese Science Bulletin2012，57，15： | 6 |
| 9 | Alterations in cecal microbiota of Jinhua piglets fostered by a Yorkshire sow显示文摘Gut microbiota play important roles in host health and diseases.Several factors,in particular antibiotics,affect the gut microbiota of pigs.Cross-fostering has been applied as a regular practice to equalize litter size,reduce pre-weaning mortality and increase body weight.However,the effect of cross-fostering on cecal microbiota is unclear.In this study,we fostered three Jinhua pigs to a Yorkshire sow.The fostered Jinhua piglets grew significantly faster than their biological siblings.To explore whether the cecal microbiota of piglets will alter during fostering,we characterized the cecal microbiota of allpiglets by examining the V3 hypervariable region of 16S rDNA.We observed altered cecal microbiota in these piglets using the Illumina HiSeq 2000 platform,and this was accompanied with an increase in growth rate after fostering.The relative abundance of Bacteroidetes in the fostered Jinhua piglets was decreased compared with their biological siblings,although still higher in comparison with their new littermates.Beta-diversity analysis also showed that the cecal microbiota of the adopted Jinhua piglets differed from their biological siblings with a shift toward their step-siblings.Our data show that cecal microbiota of piglets were altered after cross-fostering while the growth rate increased. | Lingjin Xian Ying Li Zhi Jiang Jideng Ma Long Jin Lei Chen Chaowei Zhou Jie Zhang Yingkai Liu Li Zhu An-an Jiang Guoqing Tang Jian Xiao Jinyong Wang Bo Zeng Mingzhou Li Xuewei Li | 2014 | Chinese Science Bulletin2014，59，32： | 4 |

| 11 | Fintech,regtech,and financial development:evidence from China显示文摘This study investigates the influence of fintech on developments in China’s financial sector across 290 cities and 31 provinces between 2011 and 2018.Using a two-stage least squares instrumental variable regression approach and correcting for cross-sectional dependency,simultaneity,and endogeneity of regressors,the results establish a positive link between fintech and financial development.Our findings show that fintech supports financial sector development by enhancing access(loans),depth(deposits),and savings within China’s financial institutions.We also show that the emergence of fintech in the area of financial regulation(regulatory technology:regtech)can significantly improve financial development outcomes.Therefore,it is imperative for regulators to pursue policies that balance growth in the fintech sector while mitigating the associated risks.In addition,we use the difference-in-differences approach to show that policy measures such as interest rates liberalization also positively impacted finan-cial development during the analysis period.In our conclusion,we suggest a policy framework for balanced fintech sector growth in developing countries. | Tadiwanashe Muganyi Linnan Yan Yingkai Yin Huaping Sun Xiangbin Gong Farhad Taghizadeh-Hesary | 2022 | Financial Innovation2022，8，1： | 3 |

| 13 | The nonmarine environment of Quaternary foraminifers in Yanghuzhuang, China: Evidence from boron and strontium isotopes显示文摘The concentrations and isotopic compositions of boron and strontium of Quaternary foraminifers and bivalve fossils collected in the Yanghuzhuang section of Yanqing, Beijing and of modern gastropods living in the Guishui River and of river water were measured. The concentrations and isotopic compo- sitions of Quaternary foraminifers and bivalve fossils differed from those of modern marine fo- raminifers and were similar to those of modern terrestrial gastropods from the Guishui River. These results indicate that early Quaternary foraminifers in the Yanghuzhuang section inhabited a nonmarine environment and that these foraminifers were not the result of a transgression or sea flooding. The foraminifers were not special halobios and can survive in the terrestrial condition that resembled those of the ocean. | XIAO YingKai XIAO Jun ZHAO ZhiQi HE MaoYong LI ShiZhen | 2008 | Chinese Science Bulletin2008，53，14： | 3 |
| 14 | Review of controlled clinical trials on acupuncture versus sham acupuncture in Germany显示文摘OBJECTIVE: To examine German controlled clinical trials on the therapeutic effects of acupuncture vs sham acupuncture, and to find whether there are problems with the conclusion that sham acupuncture has no significant deviation from acupuncture. METHODS: We focused on literature from the last ten years (2002-2011) included in PubMed about controlled clinical trials on acupuncture vs sham acupuncture carried out in Germany. The methods applied in sham acupuncture are summarized, and the difference between the acupuncture and sham groups were analyzed. We measured effects based on the following criteria: acupuncture is effective and superior to sham, acupuncture is effective but similar to sham, both of them have uncertainty regarding treatment effect, or no significant effect. Finally, we reviewed the hypotheses of different scholars on sham acupuncture and analyzed their results.RESULTS: Four types of controlled clinical trials including sham acupuncture on non-Traditional Chinese Medicine acupoints, minimal acupuncture on non-acupoints, placebo needle and sham laser acupuncture had varying results in the 57 articles analyzed. Some showed that acupuncture had a better effect than sham, while some suggest acupuncture and sham had similar effects. In all studies using sham acupuncture on non-therapeutic points, sham electrodes, and sham electro-acupuncture, the therapeutic effect was better than sham. Of the trials, 37 demonstrated that acupuncture had a better effect than sham acupuncture. Only nine trials found no significant difference between acupuncture and sham. Two controlled trials for the same condition (neck pain) conducted by two different German research institutes used the same control method, but reached contradictory conclusions. CONCLUSION: We found problems in conclusions based on results of controlled clinical trials of sham acupuncture in Germany. Therefore, there is still not enough evidence to support the statements that 'acupuncture and sham acupuncture have no difference in treatment effect' and 'acupuncture is just a placebo effect.' The control methods of sham acupuncture used in Germany may not be standardized and may not be suitable for acupuncture clinical trial research. We suggest that research on the methodology of sham acupuncture should be given priority in the design of acupuncture trials in the future. | Wei He Yuanyuan Tong Yingkai Zhao Li Zhang Hui Ben Qingguang Qin Feng Huang Peijing Rong | 2013 | Journal of Traditional Chinese Medicine2013，33，3： | 2 |
| 15 | Sample preparation for isotopic determination of boron in clay sediments显示文摘The procedures of sample preparation for isotopic determination of boron in clay sediments is very cumbersome, by far, there haven't been relevant reports on that. In order to establish an effective method for sample preparation, a series of experiments were carried out. In this paper, boron in clay sediments was extracted with HCl solution and purified by two-step ion exchange method. Extracted HCl solution should be adjusted to alkalescency before passing through the Amberlite IRA 743 resin column due to the fact that Amberlite IRA 743 resin absorbs boron only from alkalescent solution. However, a mass of hydroxides of Al and Fe will be precipitated when the extracted HCl solution becomes alkalescent. Hydroxides of Al and Fe have a strong adsorption capacity for boron, which can cause boron isotope fractionation. To treat precipitated hydroxides of Al and Fe, four procedures, namely direct ion exchange (DRIE), decationizing ion exchange (DCIE), once sedimentation ion exchange (OSIE) and repeated sedimentation ion exchange (RSIE) were used and assessed. The influences of the four procedures on separation and extraction and isotopic composition of boron in experimental solutions and clay sediments were also discussed. According to the results, the DRIE, DCIE and OSIE are improper. The result of sample determination indicates that when extracting boron via RSIE, with the increase of precipitation times, there's an obvious decrease in boron content in the precipitated hydroxides while a sharp increase in recovery of boron and it is favorable for weakening the influence of boron isotope fractionation. But the process of RSIE is time consuming and it may introduce boron. It needs further research to establish a more effective sample preparation method for isotopic deter- mination of boron in clay sediments. | ZHANG Yanling XIAO Yingkai MA Yunqi ZHUGE Qin LIU Zhiqi HE Maoyong LUO Chongguang MA Haizhou | 2013 | Chinese Journal Of Geochemistry2013，32，2： | 2 |

| 19 | Impact analysis of human factors on power system operation reliability显示文摘Along with the improvement of electrical equipment reliability,people’s unsafe behaviors and human errors have become one of main sources of risks in power systems.However,there is no comprehensive study on human factors and human reliability analysis in power systems.In allusion to this situation,this paper attempts to analyze the impact of human factors on power system reliability.First,this paper introduces current situation of human factors in power systems and the latest research progress in this field.Several analysis methods are proposed according to specified situations,and these methods are verified by some power system practical cases.On this base,this paper illustrates how human factors affect power system operation reliability from 2 typical aspects:imperfect maintenance caused by human errors,and impact of human factors on emergency dispatch operation and power system cascading failure.Finally,based on information decision and action in crew(IDAC),a novel dispatcher training evaluation simulation system(DTESS)is established,which can incorporate all influencing factors.Once fully developed,DTESS can be used to simulate dispatchers’response when encountering an initial event,and improve power system dispatching reliability. | Yingkai BAO Chuangxin GUO Jinjiang ZHANG Jiaxin WU Suhong PANG Zhiping ZHANG | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，1： | 1 |
| 20 | QoE-Aware Proportional Fair Scheduling for Multiuser Multiservice Wireless Networks显示文摘The effective radio resource allocation algorithms,which satisfy diversiform requirements of mobile multimedia services in wireless cellular networks,have recently attracted more and more attention.This paper proposes a service-aware scheduling algorithm,in which the Mean Opinion Score (MOS) is chosen as the unified metric of the Quality of Experience (QoE).As the network needs to provide satisfactory services to all the users,the fairness of QoE should be considered.The Proportional Fair (PF) principle is adopted to achieve the trade-off between the network performance and user fairness.Then,an integer programming problem is formed and the QoE-aware PF scheduling principle is derived by solving the relaxed problem.Simulation results show that the proposed scheduling principle can perform better in terms of user fairness than the previous principle maximizing the sum of MOS.It also outperforms the max-min scheduling principle in terms of average MOS. | Wu Wenjun Zhang Yingkai Zhang Yueying Zheng Karl Wang Wenbo | 2012 | China Communications2012，9，9： | 1 |
