| 1 | Magnetostratigraphy of the late Cenozoic Laojunmiao anticline in the northern Qilian Mountains and its implications for the northern Tibetan Plateau uplift显示文摘Cenozoic sediments in the foreland basin--Jiuquan Basin in west Hexi Corridor recorded tectonic uplift information of the Qilian Mountains. High resolution paleomagnetic dating of the Laojunmiao (LJM) section across the central LJM anticline in the southern Jiuquan Basin reveals ages of the Getanggou Member, Niugetao Member in the Shulehe Formation, the Yumen Conglomerate, Jiuquan Conglomerate and Gobi Formation at >13-8.3 Ma, 8.3-4.9 Ma, 3.66-0.93 Ma, 0.84-0.14 Ma and 0.14-0 Ma, respectively. Sedimentary evolution study suggests that the Qilian Mountains should begin to rise gradually since ~8-6.6 Ma, accompanied by sedimentary environments changing from lacustrine mudstones-sandstones to alluvial conglomerates. Rapid uplift of the Qilian Mountains began at ~3.66 Ma, followed by a series of stepwise or intermittent intensive uplifts at about <1.8-1.23 Ma, 0.93-0.84 Ma and 0.14 Ma, which finally resulted in the present high Qilian Mountains. | FANG Xiaomin1,2, ZHAO Zhijun3,2, LI Jijun2, YAN Maodu2, PAN Baotian2, SONG Chunhui2 & DAI Shuang2 1.

| 2 | A three-dimensional variational ocean data assimilation system:Scheme and preliminary results显示文摘A new 3DVAR-based Ocean Variational Analysis System (OVALS) is developed. OVALS is capable of assimilating in situ sea water temperature and salinity observations and satellite altimetry data. As a component of OVALS, a new variational scheme is proposed to assimilate the sea surface height data. This scheme considers both the vertical correlation of background errors and the nonlinear temperature-salinity relationship which is derived from the generalization of the linear balance constraints to the nonlinear in the 3DVAR. By this scheme, the model temperature and salinity fields are directly adjusted from the altimetry data. Additionally, OVALS can assimilate the temperature and salinity profiles from the ARGO floats which have been implemented in recent years and some temperature and salinity data such as from expendable bathythermograph, moored ocean buoys, etc. A 21-year assimilation experiment is carried out by using OVALS and the Tropical Pacific circulation model. The results show that the assimilation system may effectively improve the estimations of temperature and salinity by assimilating all kinds of observations. Moreover, the root mean square errors of temperature and salinity in the upper depth less than 420 m reach 0.63℃ and 0.34 psu. | ZHU Jiang1,2, ZHOU Guangqing1, YAN Changxiang1, FU Weiwei1 & YOU Xiaobao1,3 1.

| 3 | Discovery of seep carbonate nodules as new evidence for gas venting on the northern continental slope of South China Sea显示文摘Seep carbonate nodules were firstlycollected from the southwestern Dongsha area onnorthern continental slope of South China Sea formineralogical and geochemical studies. The resultsof X-ray diffraction show that carbonate nodules arecomposed of Fe-rich domolite,siderite and a few cal-cite and aragonite, as well as a small quantity ofnon-carbonate minerals such as goethite, quartz andclay minerals. Fe-rich dolomite and siderite charac-terized by euhedral microcrystalline structure weredirectly precipitated at cold seeps. The δ 13C valuesfor Fe-rich dolomite and siderite in the bulk nodulesvary from ?18.24‰ to ?36.07‰, and the δ 18O valuesrange from 0.42 to 2.76‰. Their moderate depleted13C reflects that carbon origin is possibly thermoge- netic gas or mixed gas, which is evidence of gasventings in the seafloor. Moreover, massive wormtube fossils related to cold seeps were found on thesurfaces of carbonate nodules, and the conduitsand/or channels in semi-solidified nodules whichwere not filled by carbonate or sediment were alsoobserved. A preliminary conclusion is that activemicro gas venting with a conduit/channel diameterrange from 200 μm to 600 μm possibly exists inmodern seafloor of the carbonate nodule area. | CHEN Zhong1,2,3, YAN Wen1,2,3, CHEN Muhong1,3, WANG Shuhong1,2,3, LU Jun1,3, ZHANG Fan1,3, XIANG Rong1,3, XIAO Shangbin1,3, YAN Pin1,2,3 & GU Senchang1,2,3 1.

| 4 | Randomization of classical inference patterns and its application显示文摘By means of randomization, the concept of D-randomized truth degree of formulas in two-valued propositional logic is introduced, and it is proved that the set of values of D-randomized truth degree of formulas has no isolated point in [0,1]. The concepts of D-logic pseudo-metric and D-logic metric space are also introduced and it is proved that there is no isolated point in the space. The new built D-randomized concepts are extensions of the corresponding concepts in quantified logic. Moreover, it is proved that the basic logic connectives are continuous operators in D-logic metric space. Lastly, three different types of approximate reasoning patterns are proposed. | WANG GuoJun1,2 & HUI XiaoJing1,31 Institute of Mathematics, Shaanxi Normal University, Xi’an 710062, China 2 Research Center for Science, Xi’an Jiaotong University, Xi’an 710049, China 3 College of Mathematics and Computer Science, Yan’an University, 716000, China | 2007 | Science in China(Series F)2007，50，6： | 26 |

| 7 | Palaeogene fossil Populus leaves from Lanzhou Basin and their palaeoclimatic significance显示文摘An angiosperm compression flora is found in Palaeogene from Lanzhou Basin and the cuticular analysis of Populus davidiana Dode in the flora is carefully made. Fur-thermore, the fossil cuticles are compared with the epidermal structures of extant Populus leaves growing in different en-vironments, i.e. moist, semimoist, and semiarid to arid cli-matic regions. The present experiments indicate that mature leaves of P. davidiana show leaf size from big to small, leaf cuticles from thick to thin and anticlinal walls of epidermal cells from faintness to clarity along with the increase of lati-tudes of the plant distributions, the climatic variation from moist to arid, the annual precipitation from more to less and the annual mean temperature from high to low. The fossil P. davidiana differs from the specimens collected from Shandan in semiarid to arid climatic regions but closely resembles the Wushan leaves in a semi-moist climatic area in a lot of fea-tures. In a word, the new research may reflect that the flora lives in a semi-moist climatic environment. The present dis-covery of compression of Paleogene Populus davidiana is of great significance to studying vegetation types, climatic and environmental changes during the primal uplifting of the Qinghai-Tibet Plateau. | SUN Bainian1,2, YAN Defei1, XIE Sanping1, CONG Peiyun1, XIN Cunlin1 & YUN Fei1 1.

| 8 | Investigation of the effect of berberines alkaloids in Coptis chinensis Franch on Bacillus shigae growthby microcalorimetry显示文摘The inhibitory effects of five berberines alkaloids (BAs) from rhizoma of Coptis chinensis Franch, a traditional Chinese medicinal (TCM) herb, on Bacillus shigae (B. shigae) growth were investigated by microcalorimetry. The power-time curves of B. shigae with and without BAs were acquired; meanwhile, the extent and duration of inhibitory effects on the metabolism were evaluated by growth rate constants (k1, k2), half inhibitory ratio (IC50), maximum heat output (Pmax), and peak time (tp). The values of k1 and k2 of B. shigae in the presence of the five BAs decreased with the increasing concentrations of BAs. Moreover, Pmax was reduced, and the value of tp increased with increasing concentrations of the five drugs. The inhibitory activity varied with different drugs. IC50 of the five BAs was respectively 75 μg/mL for berberine, 90 μg/mL for coptisine, 115 μg/mL for palmatine, 220 μg/mL for epiberberine, and 400 μg/mL for jatrorrhizine. The sequence of antimicrobial activity of the five BAs: berberine > coptisine > palmatine > epiberberine > jatrorrhizine. The functional groups methylenedioxy at C2 and C3 on phenyl ring improve antimicrobial activity more strongly than methoxyl at C2 and C3 on phenyl ring. However, the effect of bacteriostasis is not significant with methylenedioxy or methoxyl at C9 and C10 on phenyl ring. | YAN Dan1,2,3, JIN Cheng1, XIAO XiaoHe1 & DONG XiaoPing2 1 Institute of Chinese Medicine, 302 Hospital of People’s Liberation Army, Beijing 100039, China 2 Chengdu University of Traditional Chinese Medicine, Chengdu 610075, China 3 Chongqing Institute of Technology, Chongqing 400050, China | 2007 | Science China Chemistry2007，50，5： | 20 |
| 9 | A study on environmental aridity over northern and southern to Qinling Mountains under climate warming显示文摘Based on the data up to 1999 from hydroclimatological departments, this paper analyzes the climatic divide implications of the Qinling Mountains in regional response to the process of climate warming, due to which the grades of dryness/wetness (GDW) in 100 years show that the northern region has entered a drought period, while the southern is a humid period. In a course of ten years, the D-value of annual average air temperature over southern Shaanxi (the Hanjiang Valley) and the Central Shaanxi Plain (the Guanzhong Plain) has narrowed, i.e., the former with a slight change and the latter with rapid increase in temperature. Both regions were arid with the decrease in precipitation D-value, namely the plain became warmer while the south was drier. The Qinling Mountains play a pronounced role in the climatic divide. The runoff coefficient (RC) of the Weihe River decreases synchronously with that of the Hanjiang due to climate warming. The RC of Weihe dropped from 0.2 in the 1950s to less than 0.1 in the 1990s. The Weihe Valley (the Guanzhong Plain) is practically an arid area due to shortage of water. The successive 0.5, 1.0 oC temperature anomaly over China marks, perhaps, the important transition period in which the environment becomes more vulnerable than before.The study shows the obvious trend of environmental aridity, which is of help to the understanding of regional response to global climate change. | YAN Jun-ping~1, LIU Yan-sui~2 (1.

| 12 | Quantum secret sharing between multiparty and multiparty with four states显示文摘A protocol of quantum secret sharing between multiparty and multiparty with four states was presented. It was shown that this protocol can nullify the Trojan horse attack with a multi-photon signal, the fake-signal attack with Einstein-Podolsky- Rosen pairs, the attack with single photons, and the attack with invisible photons. In addition, the upper bounds of the average success probabilities were given for dishonest agent eavesdropping encryption using the fake-signal attack with any two-particle entangled states. | YAN FengLi1, GAO Ting2 & LI YouCheng1 1 College of Physics and Information Engineering, Hebei Normal University, Shijiazhuang 050016, China 2 College of Mathematics and Information Science, Hebei Normal University, Shijiazhuang 050016, China | 2007 | Science China(Physics,Mechanics & Astronomy)2007，50，5： | 18 |
| 13 | Land cover changes based on plant successions: Deforestation, rehabilitation and degeneration of forest in the upper Dadu River watershed显示文摘To link regional land use/cover changes with environmental effects, land cover changes are required to reflect vegetation successions, whereas the land cover classification systems commonly used nowadays cannot serve this purpose. In this paper, a new land cover classification system is established in which land covers are classified by the vegetation succes-sions, taking Zamtang County, Barkam County and Jinchuan County in the upper Dadu River watershed as a study area. Using multi-temporal remote sensing images, the land cover data of 1967, 1986 and 2000 are obtained by means of integration of unsupervised classification and visual interpretation methods. The database facilitates the study of land use/cover changes, en-vironmental effects and ecological construction. Land cover changes reflect the main ecological processes in the upper Dadu River watershed. The landscape composed mainly of grasslands, wildwoods and alpine scrubs in 1967 was changed to that of grasslands, secondary forests, al-pine scrubs, fragmentary wildwoods, artificial forests, secondary scrubs in 2000, meanwhile, the landscape got more fragmentized. The total area of the forests decreased by 9.43%. Study results have shown the process of restoration of logged areas in forest centers. From 1967 to 2000, only 6.86 percents of logged areas were converted to shrubs, meadows or crop-lands, and the rest were converted into artificial forests or secondary forests. So the ecological shelter functions will be restored, stage by stage. Firewood collection, charcoal production and overgrazing are the three major triggers for the extensive degradation of alpine oak forests, Sa-bina tibetica forests and meadows. The arid valley grasslands expanded too. The degradation of vegetation in the southern slopes impairs ecological shelter functions and affects livelihood of local residents, so it is essential to find effective measures for ecological restoration and recon-struction. Field investigations have found that the current measures have not concerned with how to keep the livelihood of local farmers and herders. The most important measure for ecological protection and restoration is to help the farmers and herders to raise the living standard, which means that they will never need to rely only on the colonizing of croplands, the logging of forests and the grazing of livestock to make a living. | YAN Jianzhong1,2,3, ZHANG Yili1, BAI Wanqi1, LIU Yanhua4, BAO Weikai5, LIU Linshan1, 2 & ZHENG Du1 1.

| 14 | Association between Serum Homocysteine and Oxidative Stress in Elderly Patients with Obstructive Sleep Apnea/hypopnea Syndrome显示文摘Objective Elderly patients with obstructive sleep apnea/hypopnea syndrome(OSAHS)has a higher risk of cardiovascular and cerebrovascular disease.However,changes of homocysteine(Hcy)as markers of cardiovascular and cerebrovascular disease associated with OSAHS and their mechanism have not been elucidated so far.This study aims to investigate the changes of both serum Hcy and oxidative stress and their possible links with OSAHS in elderly patients.Methods Based on polysomnogram(PSG)and age,83 patients with OSAHS were recruited and divided into elderly-OSAHS(n=32)and non-elderly OSAHS groups(n=51).Fifty two subjects without OSAHS were divided into elderly control(n=29)and non-elderly control groups(n=23).A total of 135 subjects were included in the present study.All subjects were recorded for PSG variables and the contents of homocysteine(Hcy),malonaldehyde(MDA),and glutathione(GSH)which were detected after sleep.Serum homocysteine was measured by cyclophorase.MDA and GSH were measured by spectrophotometer.Results(1)The serum levels of Hcy showed significant difference among the four groups(P<0.05).The concentrations of Hcy in elderly OSAHS patients were higher than in other groups,while those in the elderly control group were higher than in the non-elderly control the concentrations in the non-elderly OSAHS group were higher than in the non-elderly control.(2)The concentrations of MDA and GSH changed at an equal pace with Hcy in the four groups.(3)Multielement linearity regression analysis indicated a statistically significant relationship between Hcy concentration and age,MDA,GSH,and apnea hypopnea index(AHI).Conclusions(1)The concentrations of Hcy and oxidative stress have increased with advancing age.(2)The concentrations of Hcy and oxidative stress have further increased in the elderly patients with OSAHS.(3)Oxidative stress might cause high-level serum Hcy in the elderly patients with OSAHS. | LING WANG,JIE LI 2,YAN XIE,AND XUE-GUANG ZHANG Laboratory of Clinical Immunology,the First Affiliated Hospital of Soochow University,Suzhou 215006,Jiangsu,China | 2010 | Biomedical and Environmental Sciences2010，23，1： | 15 |
| 15 | Quantum secret sharing between m-party and n-party with six states显示文摘A quantum secret sharing scheme between an m-party group and an n-party group is proposed using three conjugate bases.A sequence of single photons,each of which is prepared in one of the six states,is used directly to encode classical information in the quantum secret sharing process.In this scheme,each of all m members in group 1 chooses randomly his/her own secret key individually and independently,and directly encodes his/her respective secret information on the states of single photons via unitary operations,then the last one sends 1/n of the resulting qubits to each member of group 2.By measuring their respective qubits,all members in group 2 share the secret information shared by all members in group 1.It renders impossible a Trojan horse attack with a multi-photon signal,a fake-signal attack with EPR pairs,an attack with single photons,and an attack with invisible photons.We give the upper bounds on the average success probabilities for dishonest agent eavesdropping encryption using the fake-signal attack with any two-particle entangled states. | GAO Ting1,YAN FengLi2,3 & LI YouCheng2,3 1 College of Mathematics and Information Science,Hebei Normal University,Shijiazhuang 050016,China 2 College of Physics and Information Engineering,Hebei Normal University,Shijiazhuang 050016,China 3 Hebei Advanced Thin Films Laboratory,Shijiazhuang 050016,China | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，8： | 15 |
