| 1 | The characteristics of atmospheric CO_2 concentration variation of four national background stations in China显示文摘Atmospheric carbon dioxide is an important kind of greenhouse gas which influences global temperature. Its concentration variation could indicate the distribution of human and natural activities in various regions. Through the non-dispersive infrared method, flask sampling of atmospheric CO2 concen- tration was measured weekly at four national background stations including Waliguan, Shangdianzi, Lin’an, and Longfengshan. Based on the data collected from September 2006 to August 2007, along with the Waliguan station’s experience on in situ observational data processing, the selection methods for sampling data through the atmospheric background CO2 concentration analysis were preliminarily discussed. On the basis of this result, the variation features of the four typical regions’ atmospheric background CO2 concentration was analyzed for the first time. The results show that the atmospheric CO2 concentration at Waliguan, Shangdianzi, Lin’an, and Longfengshan is 383.5, 385.9, 387.8, and 384.3 ppm, respectively. During the research period, CO2 concentration at the Waliguan station changed slightly. However, the CO2 concentration changed sharply at the Shangdianzi and the Lin’an stations due to the great influence of human activities in the Jingjinji and the Changjiang Delta economic zones, and changed regularly with seasons at Longfengshan station under dual influences of human activities and plant photosynthesis. The results from this study can lay the foundation for more profound studies on atmospheric CO2 concentration level of different areas in China, and could be used to improve the understanding of carbon source and sink distribution. | LIU LiXin, ZHOU LingXi, ZHANG XiaoChun, WEN Min, ZHANG Fang, YAO Bo & FANG ShuangXi Key Laboratory for Atmospheric Chemistry, Centre for Atmosphere Watch and Services (CAWAS), Chinese Academy of Meteoro- logical Sciences (CAMS), China Meteorological Administration (CMA), Beijing 100081, China | 2009 | Science China Earth Sciences2009，52，11： | 26 |

| 4 | 从“园丁式监管”走向“大数据监管”——对互联网金融生态体系特征与监管模式创新的思考显示文摘互联网和金融的融合已成趋势。在互联网金融中,尽管金融的功能属性和风险属性依旧存在,但一些有别于传统金融的现象已经呈现,诸如货币去纸化、金融平台数据化、金融服务分子化和碎片化,以及金融系统去中心化等,而这一切都可以归纳为互联网金融生态系统的蜕变性、多样性和进化性等特征。有鉴于此,目前以'产品逻辑+机构逻辑+分业监管'为核心的监管模式,迫切需要做出调整。我们认为,监管机构需要与行业组织、互联网金融企业、消费者及其他利益相关者一道,共同构建一个良性监管机制。我们建议监管机构采取'园丁式监管'模式,以'包容性'和'底线思维'来防范风险、以'自然选择'来促进效率提升、以'适时修剪'来规范行业运作,逐步过渡到'大数据监管'模式,即围绕数据的生成、传输和使用等环节,采取实时和互动方式,实现对互联网金融的有效监管。 | Researching Center, Small and Micro Financial Services Group | 2014 | 新金融评论2014，，2： | 13 |

| 7 | 提前返乡流动人口调查报告显示文摘The global financial crisis resulted in a large number of earlier return migrants in China at the end of 2008. The National Population and Family Planning Commission conducted a sample survey of the earlier return migrants in six large migrant sending provinces (Anhui,Jiangxi,Henan,Hubei,Hunan,and Chongqing) in November to December 2008. The sample includes 1177 migrant households and 81 village committees. Estimates based on the sample survey show that the number of earlier return migrants stood at 13.6 million by 20 December 2008,accounting for only 9% of the total migrant population. The majority of the earlier return migrants came from the Pearl River Delta and the Yangtze River Delta where they were largely employed in manufacturing and construction industries,however,were mostly not covered by basic public services and social security. Most of the earlier return migrants had strong desires to go back to the cities after the Spring Festival. Policy implications are discussed in the report. | Department of Floating Population Service and Management National Population and Family Planning Commission of China | 2009 | 人口研究2009，33，2： | 10 |

| 10 | Environmental Implications of Excessive Selenium: A Review显示文摘Selenium is a naturally occurring trace element that is nutritionally required in smallamounts but it can become toxic at concentrations only twice those required. The narrow mar-gin between beneficial and harmful levels has important implications for human activities thatincrease the amount of selenium in the environment. Two of these activities, disposal of fbssilfuel wastes and agricultural irrigation of arid, seleniferous soils, have poisoned fish andwildlife, and threatened public health at several locations in the United States. Research stud-ies of these episodes have generated a data base that clearly illustrates the environmental hazardof excessive selenium. It is strongly bioaccumulated by aquatic organisms and even slight in-creases in waterborne concentrations can quickly result in toxic effects such as deformed em-bryos and reproductive failure in wildlife. The selenium data base has been very beneficial indeveloping hazard assessment procedures and establishing environmentally sound water qualitycriteria. The two faces of selenium, required nutrient and Potent toxin, make it a particularlyimportant trace element in the health of both animals and man. Because of this paradox, envi-ronmental selenium in relation to agriculture, fisheries, and wildlife wiIl continue to raise im-POrtant land and water management issues for decades to come. If these issues are dealt withusing prudence and the available environmental selenium data base, adverse irnpacts to naturalresources andspublic health can be | A.

| 12 | Evaluation of genetic diversity in Chinese indigenous chicken breeds using microsatellite markers显示文摘China is rich in chicken genetic resources, and many indigenous breeds can be found throughout the country. Due to poor productive ability, some of them are threatened by the commercial varieties from domestic and foreign breeding companies. In a large-scale investigation into the current status of Chinese poultry genetic resources, 78 indigenous chicken breeds were surveyed and their blood samples collected. The genomes of these chickens were screened using microsatellite analysis. A total of 2740 individuals were genotyped for 27 microsatellite markers on 13 chromosomes. The number of alleles of the 27 markers ranged from 6 to 51 per locus with a mean of 18.74. Heterozy-gosity (H) values of the 78 chicken breeds were all more than 0.5. The average H value (0.622) and polymorphism information content (PIC, 0.573) of these breeds suggested that the Chinese indige-nous chickens possessed more genetic diversity than that reported in many other countries. The fixa-tion coefficients of subpopulations within the total population (FST) for the 27 loci varied from 0.065 (LEI0166) to 0.209 (MCW0078), with a mean of 0.106. For all detected microsatellite loci, only one (LEI0194) deviated from Hardy-Weinberg equilibrium (HWE) across all the populations. As genetic drift or non-random mating can occur in small populations, breeds kept on conservation farms such as Langshan chicken generally had lower H values, while those kept on large populations within con-servation regions possessed higher polymorphisms. The high genetic diversity in Chinese indigenous breeds is in agreement with great phenotypic variation of these breeds. Using Nei’s genetic distance and the Neighbor-Joining method, the indigenous Chinese chickens were classified into six categories that were generally consistent with their geographic distributions. The molecular information of genetic diversity will play an important role in conservation, supervision, and utilization of the chicken re-sources. | QU Lujiang1, LI Xianyao1, XU Guifang2, CHEN Kuanwei3, YANG Hongjie2, ZHANG Longchao1, WU Guiqin1, HOU Zhuocheng1, XU Guiyun1 & YANG Ning1 1.

| 13 | Threshold quantum secret sharing between multi-party and multi-party显示文摘A threshold quantum secret sharing (TQSS) scheme between multi-party and multi-party was proposed using a sequence of single photons,which is useful and efficient when the parties of communication are not all present. We described the process of this TQSS scheme and discussed its security. It was shown that entan-glement is not necessary for quantum secret sharing. Moreover,the theoretic effi-ciency was improved to approach 100% as almost all the instances can be used for generating the private key,and each photon can carry one bit of information. This protocol is feasible with the present-day technique. | YANG YuGuang1,2,3 & WEN QiaoYan4 1 College of Computer Science and Technology,Beijing University of Technology,Beijing 100124,China 2 State Key Laboratory of Integrated Services Network,Xidian University,Xi’an 710071,China 3 State Key Laboratory of Information Security (Graduate University of Chinese Academy of Sciences),Beijing 100049,China 4 State Key Laboratory of Networking and Switching Technology,Beijing University of Posts and Tele-communications,Beijing 100876,China | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，9： | 8 |
| 14 | Experimental studies on perturbed acoustic resonant spectroscopy by a small rock sample in a cylindrical cavity显示文摘A measurement system for acoustic resonant spectroscopy (ARS) is estab-lished,and the effects of resonant cavity geometry,inner perturbation samples and envi-ronmental temperature on the ARS are investigated. The ARSs of the small samples with various sizes and acoustic properties are measured. The results show that at the normal pressure,the resonant frequency decreases gradually with the increase of liquid tem-perature in the cylindrical cavity,while the resonant amplitude increases. At certain pres-sure and temperature,both the resonant frequency and the amplitude decrease greatly when there exist air bubbles inside the cavity fluid. The ARS is apparently affected by the sample porosity and the sample location in the resonant cavity. At the middle of the cavity,the resonant frequencies reach their maximum values for all of the measurement samples. The resonant frequencies of the porous rock samples are smaller than those of the com-pacted samples if other acoustic parameters are the same. As the sample is moved from the top to the middle of the cavity along its axis,the resonant amplitude increases gradu-ally for the compacted rocks while decreases for the unconsolidated rocks. Furthermore,the resonant amplitude increases firstly and then decreases if the porosity of the rock sample is relatively small. In addition,through the comparisons between the experimental and theoretical results,it is found that the effects of the acoustic parameters and sizes of the samples and the size of the cylindrical cavity on the laboratory results agree well with the theoretical ones qualitatively. These results may provide basic reference for the ex-periment study of rock acoustic properties in a low frequency using ARS. | CHEN Dehua1,2,WANG Xiuming2,3,CONG Jiansheng1,XU Delong1,SONG Yanjie1 & MA Shuilong4 1.

| 16 | Paleotemperature changes over the past 3000 years in eastern Beijing, China: A reconstraction based on Mg/Sr records in a stalagmite显示文摘The Mg/Sr ratio in a stalagmite, which is di-rectly proportional to DMg/Ca, the solid-liquid distribution coefficient of Mg, is proposed as a geochemical thermometer to estimate paleotemperature changes. The paleotempera-ture change in eastern Beijing over the past 3000 years has been reconstructed by using this thermometer in the stalag-mite ZFFS-1 from Jingdong Cave. The records can be di-vided into two periods: 3000—2000 aBP, cool and wet, the air temperature averaging 9.8℃; and 2000 aBP—present, hot and dry, the air temperature being 1℃ higher than the mean value (11.7℃) of the past 3000 years. During 500—200 aBP, the air temperature was about 1.2℃ lower than that of the present, corresponding to the Little Ice Age in Europe. Like d 18O and d 13C, Mg/Sr (or DMg/Ca) reflects an obviously warming trend of the past 200 years. These results are sup-ported by historic records. | MA Zhibang1, LI Hongchun2, XIA Ming1, KU Tehlung2, PENG Zicheng3, CHEN Yushu4 & ZHANG Zhaofeng3 1.

| 19 | An analysis of the wide area differential method of geostationary orbit satellites显示文摘This work aims to obtain a wide area differential method for geostationary orbit (GEO) constellation. A comparison between the dilution of precision (DOP) of four-dimensional (4D) calculation including sa- tellite clock errors and ephemeris errors and that of three-dimensional (3D) calculation only including ephemeris errors with the inverse positioning theory of GPS shows the conclusion that all the 3D PDOPs are greatly reduced. Based on this, a basic idea of correcting satellite clock errors and ephem- eris errors apart is put forward, and moreover, a specific method of separation is proposed. Satellite clock errors are separated in a master station with time synchronization, and all the remaining pseu- do-range errors after the satellite clock errors have been deducted are used to work out ephemeris corrections of all GEO satellites. By a comparative analysis of user positioning accuracy before and after differential, the wide area differential method is verified to be quite valid for GEO constellation. | CAI ChengLin1,2,3?, LI XiaoHui1 & WU HaiTao1 1 National Time Service Center, Chinese Academy of Sciences, Lintong 710600, China 2 Hunan Institute of Humanities, Science and Technology, Loudi 417000, China 3 Graduate University of Chinese Academy of Sciences, Beijing 100049, China | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，2： | 7 |
