| 1 | Distribution of Pacific-origin water in the region of the Chukchi Plateau in the Arctic Ocean in the summer of 2003显示文摘The upper ocean thermohaline structures in the region of the Chukchi Plateau are analyzed with the hydrographic data collected by the Chinese National Arctic Research Expedition in the summer of 2003. Three types of the Pacific-origin water were found in the upper ocean, Alaska Coastal Water (ACW), summer Bering Sea Water (sBSW) and winter Bering Sea Water (wBSW) are indicated by two maximums temperature and one minimum temperature, piling up from the upper to the lower respectively. The extreme warm ACW with a maximum temperature of 1.62 ℃ was found in the southwestern Canada Basin at a depth of about 50 m. A pathway of the ACW into the basin from its adjacent area did not existed in the expedition period. So it is speculated that the extreme warm feature of the ACW was formed locally in 2003. The relative weak ACW occurred to the east of the Chukchi Cap and in the southern Chukchi Abyssal Plain. The latter one might originate from a warm downwelling that existed in a small canyon at the shelf break of the Chukchi Sea. The sBSW without the ACW was found only at the southwestern flank of the Chukchi Cap. The ACW and the sBSW were not found in the northernmost station at 81°N,which indicates the north boundary of the upper Pacific-origin water in the Canada Basin. The wBSW, which existed in all deep stations,was exactly uniform at temperature. The difference of the core potential temperature of the wBSW in the deep regions is only 0.08 ℃. | SHI Jiuxin CAO Yong ZHAO Jinping GAO Guoping JIAO Yutian LI Shujiang | 2005 | Acta Oceanologica Sinica2005，24，6： | 15 |

| 3 | Distributed modeling of monthly air temperatures over the rugged terrain of the Yellow River Basin显示文摘Our analyses of the monthly mean air temperature of meteorological stations show that altitude,global solar radiation and surface effective radiation have a significant impact on air temperature.We set up a physically-based empirical model for monthly air temperature simulation.Combined the proposed model with the distributed modeling results of global solar radiation and routine meteorological observation data,we also developed a method for the distributed simulation of monthly air temperatures over rugged terrain.Spatial distribution maps are generated at a resolution of 1 km×1 km for the monthly mean,the monthly mean maximum and the monthly mean minimum air temperatures for the Yellow River Basin.Analysis shows that the simulation results reflect to a considerable extent the macro and local distribution characteristics of air temperature.Cross-validation shows that the proposed model displays good stability with mean absolute bias errors of 0.19℃-0.35℃.Tests carried out on local meteorological station data and case year data show that the model has good spatial and temporal simulation capacity.The proposed model solely uses routine meteorological data and can be applied easily to other regions. | ZENG Yan QIU XinFa HE YongJian SHI GuoPing LIU ChangMing | 2009 | Science China Earth Sciences2009，52，5： | 11 |
| 4 | Effect of dry density on ^(125)I diffusion in GMZ bentonite显示文摘Gaomiaozi(GMZ) bentonite is regarded as the favorable candidate backfilling material for a potential repository in China.It is important to understand the diffusion behavior of 125 I in GMZ bentonite and compare the diffusion behavior in GMZ and other types of bentonite like MX-80,Avonlea,etc.Therefore,through-and out-diffusion experiments were conducted to obtain the effective diffusion coefficient(D e) and distribution coefficient(K d).A computer code named Fitting for diffusion coefficient(FDP) was used for the experimental data processing and theoretical modeling.At the dry density of GMZ bentonite from 1600-2000 kg/m 3,the D e values of 125 I were(2.4-20.4) × 10-12 m 2 /s and K d values were constants.At dry density above 1800 kg/m 3,the diffusion behaviors were almost the same,indicating that the anion exclusion was ineffective.Out-diffusion results showed that the species of 125 I may be changed during the diffusion processing.It was probably caused by some organic matters or reducing substances in GMZ bentonite.Since the main composition of bentonite is montmorillonite,similar diffusion parameters were obtained in GMZ and other types of bentonite.The relationship of D e and accessible porosity(acc) could be described by Archie's law with exponent n = 1.2-2.8 for 125 I diffusion in bentonite,whereas n = 2.0 in GMZ bentonite.Furthermore,bentonite with the dry density of 1800 kg/m 3 was proposed as the backfilling materials used in the construction of high level radioactivity waste repository. | WU Tao LI JinYing DAI Wei XIAO GuoPing SHU FuJun YAO Jun SU YuLan SHI Lei | 2012 | Science China Chemistry2012，55，9： | 11 |
| 5 | Water mass of the northward throughflow in the Bering Strait in the summer of 2003显示文摘The temperature and salinity data obtained by the Chinese national arctic research expedition (CHINARE2003) are used to study the water structure in the Bering Strait and ambient regions. Four water masses appeared in the research region: the intermediate Bering Sea water mass (IBWM), the Alaska coastal water (ACW), the Anadyr water (AW) and the Bering shelf water (BSW). The AW originates from the IBWM, but the upper layer water has been greatly altered. In the cruise on 28/29 July 2003, there were only the BSW and ACW in a section across the Bering Strait (BS section), but in the September 12/13 cruise, the AW, BSW and ACW flowed parallelly into the Bering Strait. The upper waters of these water masses were all altered due to ice melting, runoff, solar radiation, and wind mixing. The waters in the central and northern parts of Bering Strait stratified by two uniform layers,were expressed as the typical feature of the water masses originating from the pacific. A two-layer structure also dominated the vertical stratification in most part of the Chukchi Sea. An obvious subseasonal variation was observed in the BS section, which caused varying transportation of fresh water, heat, and substance, and produced a long-term and extensive impact on the Arctic Ocean. | ZHAO Jinping SHI Jiuxin GAO Guoping JIAO Yutian ZHANG Hongxin | 2006 | Acta Oceanologica Sinica2006，25，2： | 10 |

| 8 | Combined community ecology and floristics,a synthetic study on the upper montane evergreen broad-leaved forests in Yunnan,southwestern China显示文摘The upper montane evergreen broad-leaved forest in Yunnan occurs mainly in the zone of persistent cloud and has a discontinuous,island-like,distribution.It is diverse,rich in endemic species,and likely to be sensitive to climate change.Six 1-ha sampling plots were established across the main distribution area of the upper montane evergreen broad-leaved forest in Yunnan.All trees with d.b.h.>1 cm in each plot were identified.Patterns of seed plant distributions were quantified at the specific,generic and family levels.The forests are dominated by the families Fagaceae,Lauraceae,Theaceae and Magnoliaceae,but are very diverse with only a few species shared between sites.Floristic similarities at the family and generic level were high,but they were low at the specific level,with species complementarity between plots.Diversity varied greatly among sites,with greater species richness and more rare species in western Yunnan than central Yunnan.The flora is dominated by tropical biogeographical elements,mainly the pantropic and the tropical Asian distributions at the family and genus levels.In contrast,at the species level,the flora is dominated by the southwest or the southeast China distributions,including Yunnan endemics.This suggests that the flora of the upper montane forest in Yunnan could have a tropical floristic origin,and has adapted to cooler temperatures with the uplift of the Himalayas.Due to great sensitivity to climate,high endemism and species complementarity,as well as the discontinuous,island-like,distribution patterns of the upper montane forest in Yunnan,the regional conservation of the forest is especially needed. | Hua Zhu Yong Chai Shisun Zhou Lichun Yan Jipu Shi Guoping Yang | 2016 | Plant Diversity2016，38，6： | 6 |
| 9 | Pathological changes in the lungs and lymphatic organs of 12 COVID-19 autopsy cases显示文摘Systematic autopsy and comprehensive pathological analyses of COVID-19 decedents should provide insights into the disease characteristics and facilitate the development of novel therapeutics.In this study,we report the autopsy findings from the lungs and lymphatic organs of 12 COVID-19 decedents—findings that evaluated histopathological changes;immune cell signature and inflammatory factor expression in the lungs,spleen and lymph nodes.Here we show that the major pulmonary alterations included diffuse alveolar damage,interstitial fibrosis and exudative inflammation featured with extensive serous and fibrin exudates,macrophage infiltration and abundant production of inflammatory factors(IL-6,IP-10,TNFo?and IL-I f).The spleen and hilar lymph nodes contained lesions with tissue structure disruption and immune cell dysregulation,including lymphopenia and macrophage accumulation.These findings provide pathological evidence that links injuries of the lungs and lymphatic organs with the fatal systematic respiratory and immune malfunction in critically ill COVID-19 patients. | Qian Liu Yu Shi Jun Cai Yaqi Duan Rongshuai Wang Hongyan Zhang Qiurong Ruan Jiansha Li Lei Zhao Yifang Ping Rong Chen Liang Ren Xiaochun Fei Heng Zhang Rui Tang Xi Wang Tao Luo Xindong Liu Xuequan Huang Zhenhua Liu Qilin Ao Yong Ren Jing Xiong Zhicheng He Haibo Wu Wenjuan Fu Pengnan Zhao Xinwei Chen Guoqiang Qu Yunyun Wang Xi Wang Jia Liu Dongfang Xiang Sanpeng Xu Xiaowei Zhou Qingrui Li Jinghong Ma Heng Li Jie Zhang Sizhe Huang Xiaohong Yao Yiwu Zhou Chaofu Wang Dingyu Zhang Guoping Wang Liang Liu Xiu-Wu Bian | 2020 | National Science Review2020，7，12： | 6 |
| 10 | Nutrient maximums related to low oxygen concentrations in the southern Canada Basin显示文摘The phenomenon of nutrient maximums at 70~200 m occurred only in the region of the Canada Basin among the world oceans. The prevailing hypothesis was that the direct injection of the low-temperature high-nutrient brines from the Chukchi Sea shelf (<50 m) in winter provided the nutrient maximums. However, we found that there are five problems in the direct injection process. Formerly Jin et al. considered that the formation of nutrient maximums can be a process of locally long-term regeneration. Here we propose a regeneration-mixture process. Data of temperature, salinity, oxygen and nutrients were collected at three stations in the southern Canada Basin during the summer 1999 cruise. We identified the cores of the surface, near-surface, potential temperature maximum waters and Arctic Bottom Water by the diagrams and vertical profiles of salinity, potential temperature, oxygen and nutrients. The historical 129I data indicated that the surface and near-surface waters were Pacific-origin, but the waters below the potential temperature maximum core depth was Atlantic-origin. Along with the correlation of nutrient maximums and very low oxygen contents in the near-surface water, we hypothesize that, the putative organic matter was decomposed to inorganic nutrients; and the Pacific water was mixed with the Atlantic water in the transition zone. The idea of the regeneration-mixture process agrees with the historical observations of no apparent seasonal changes, the smooth nutrient profiles, the lowest saturation of CaCO3 above 400 m, low rate of CFC-11 ventilation and 3H-3He ages of 8~18 a around the nutrient maximum depths. | JIN Ming-ming SHI Jiuxin LU Yong CHEN Jianfang GAO Guoping WU Jingfeng ZHANG Haisheng | 2005 | Acta Oceanologica Sinica2005，24，6： | 5 |
| 11 | A botanical medicine dragon’s blood exhibited clinical antithrombosis efficacy similar to low molecular weight heparin显示文摘Deep vein thrombosis(DVT)is a common complication following traumatic fracture with a 0.5%–1%annual incidence.Low molecular weight heparin(LMWH)is the most commonly used anticoagulation drug for DVT prevention,but treatment with LMWH is invasive.Our aim is to compare the antithrombotic effect of dragon’s blood,an oral botanical anticoagulant medicine approved by the Chinese FDA,with LMWH in patients undergoing hip fracture surgery and to explore the molecular mechanisms of anticoagulation treatment.Our study recruited patients and divided them into LMWH and dragon’s blood treatment group.Coagulation index tests,Doppler ultrasound and mRNA sequencing were performed before and after anticoagulation therapy.There was no significant difference in postoperative DVT incidence between the two groups(23.1%versus 15.4%,P=0.694).D-dimer(D-D)and fibrinogen degradation product(FDP)showed significant reductions in both groups after anticoagulation treatments.We identified SLC4A1,PROS1,PRKAR2B and seven other genes as being differentially expressed during anticoagulation therapy in both groups.Genes correlated with coagulation indexes were also identified.Dragon’s blood and LMWH showed similar effects on DVT and produced similar gene expression changes in patients undergoing hip fracture surgery,indicating that dragon’s blood is a more convenient antithrombosis medicine(oral)than LMWH(hypodermic injection). | Jiangbin Liang Song Mei Xiangyu Qiao Wei Pan Yan Zhao Shaohui Shi Yaling Zhai Haizhao Wen Guoping Wu Chengyu Jiang | 2021 | Science China(Life Sciences)2021，64，10： | 4 |

| 13 | Hearing analysis in heterozygous and homozygous klotho gene deficient mice显示文摘Objective: To understand the crucial role of the klotho gene in hearing development in mouse models.Methods: PCR was used to identify CBA mice with different genotypes, i.e. WT, heterozygous(klotho +/-)or homozygous(klotho-/-). Mice phenotype and weight were recorded postnatal 25 days(P-25) and auditory brainstem responses(ABR) were used to determine auditory function at P-60.Results: klotho-/-mice tended to have smaller size, lighter weight and higher ABR thresholds at P-60,showing early onset age-related hearing loss(ARHL).Conclusion: Heterozygous and homozygous klotho deficient mice exhibit different degrees of hearing loss at young age, with homozygous mice(klotho-/-) showing more severe hearing loss. Our results indicate that persisted expression of klotho protein in the inner ear may potentially delay the onset of ARHL and play an important role in the protection of auditory function. | Na Yuan Shiwei Qiu Qian Wang Wei Zhuang Guoping Li Tiantian Sun Shiming Yang Yuehua Qiao Xi Shi | 2018 | Journal of Otology2018，13，4： | 2 |

| 15 | SHOCK INITIATION OF EXPLOSIVES INVESTIGATED WITH SMALL PARTITION EXPERIMENT AND NUMERICAL SIMULATION显示文摘In order to investigate the shock ignition of high energy solid explosives by shock waves,we carry out Lagrangian experiments with 2-D Lagrangian technique which uses composite manganin-constantan(CMC).The efects of the shock sensitivity of pressed solid high explosives,TNT,and the efect of the lateral rarefaction wave were studied.Based on the measured pressure histories and the radial displacements,we formulate the Ignition and Growth reactive flow models for the pressed TNT.The shock initiation process simulated by Ignition and Growth model agreed well with experimental data.This pressed TNT model can be applied to shock initiation scenarios which are highly unpredictable and have not been or cannot be tested experimentally. | Weijun Tao Shi Huan Fenglei Huang Guoping Jiang | 2013 | Acta Mechanica Solida Sinica2013，26，4： | 2 |
| 16 | New Method for Estimating Daily Global Solar Radiation over Sloped Topography in China显示文摘A new scheme for the estimation of daily global solar radiation over sloped topography in China is developed based on the Iqbal model C and MODIS cloud fraction. The effects of topography are determined using a digital elevation model. The scheme is tested using observations of solar radiation at 98 stations in China, and the results show that the mean absolute bias error is 1.51 MJ m^(-2) d^(-1) and the mean relative absolute bias error is 10.57%. Based on calculations using this scheme,the distribution of daily global solar radiation over slopes in China on four days in the middle of each season(15 January,15 April, 15 July and 15 October 2003) at a spatial resolution of 1 km × 1 km are analyzed. To investigate the effects of topography on global solar radiation, the results determined in four mountains areas(Tianshan, Kunlun Mountains, Qinling,and Nanling) are discussed, and the typical characteristics of solar radiation over sloped surfaces revealed. In general, the new scheme can produce reasonable characteristics of solar radiation distribution at a high spatial resolution in mountain areas,which will be useful in analyses of mountain climate and planning for agricultural production. | Guoping SHI Xinfa QIU Yan ZENG | 2018 | Advances in Atmospheric Sciences2018，35，3： | 2 |

| 19 | Behavior of steel fiber-reinforced high-strength concrete at medium strain rate显示文摘Impact compression experiments for the steel fiber-reinforced high-strength concrete(SFRHSC)at medium strain rate were conducted using the split Hopkinson press bar(SHPB)testing method.The volume fractions of steel fibers of SFRHSC were between 0 and 3%.The experimental results showed that,when the strain rate increased from threshold value to 90 s^(-1),the maximum stress of SFRHSC increased about 30%,the elastic modulus of SFRHSC increased about 50%,and the increase in the peak strain of SFRHSC was 2-3 times of that in the matrix specimen.The strength and toughness of the matrix were improved remarkably because of the superposition effect of the aggregate high-strength matrix and steel fiber high-strength matrix.As a result,under impact loading,cracks developed in the SFRHSC specimen,but the overall shape of the specimen remained virtually unchanged.However,under similar impact loading,the matrix specimens were almost broken into small pieces. | Chujie JIAO Wei SUN Shi HUAN Guoping JIANG | 2009 | Frontiers of Structural and Civil Engineering2009，3，2： | 1 |
