| 1 | The Y.D.and climate abrupt events in the early and middle Holocene:Stalagmite oxygen isotope record from Maolan,Guizhou,China显示文摘The isotope records which range from 3.9 kaBP to 15.7 kaBP with an average resolution of 90 a have been obtained from 45 cm to 193.6 cm of the upper part of D4 stalagmite from Dongguo Cave in Libo, Guizhou, by using system TIMS U-series dating and carbon and oxygen stable isotope analyses.The study indicates that the last cold event, the YD (Younger Dryas) event, of the last glacial period was apparently shown in D4 record, which started from 12.80 kaBP and ended in 11.58 kaBP, with a great range of drop in temperature. The end of the last glacial period was consistent with the termination I in oceanic isotope records and was with time limit of 11.3 kaBP. The three most distinct cold events in the early and middle Holocene occurred respectively in 10.91 kaBP, 8.27 kaBP and 4.75 kaBP, with a range of drop in tem- perature reaching 2—5℃. The climate abrupt events in thousand and hundred years scale re- corded in stalagmite δ O can be compared to those in GISP2 ice cores from Greenland in their 18 happening time and the range of their lasting time. The cold events in 8.27 kaBP and 4.75 kaBP can also be compared to CC3 stalagmite records in Ireland, which indicate that climate changes of short range in China monsoon areas, western Europe and polar regions, have the same driv- ing factor. This has a global significance. In addition, the trend of record curves in some time- stages is apparently different, which reflects probably the difference between environment in monsoon climate areas and in polar regions. | QIN Jiaming1, YUAN Daoxian1, CHENG Hai2, LIN Yushi1, ZHANG Meiliang1, WANG Fuxing1, R.

| 2 | Evolution of Sedimentation and Tectonics of the Youjiang Composite Basin, South China显示文摘Located at the southern margin of the South China plate, the Youjiang basin is a closely related to the NW- and NE-trending syndepositional faults in respect to the configuration and structure of the basin. The evolution of the Youjiang basin progressed through two stages. In the Hercynian period, the opening of the Ailaoshan-Honghe ocean basin gave rise to a number of NW-trending rift belts in the Youjiang area. During this period, deep-water sediments were dominant and the basin was possesed of the characteristics of the rift system of passive continental margins. In the early Indosinian after the Dongwu movement, the circum - Pacific tectonism led to a major change in the configuration and structure of the basin. In the meantime, the Ailaoshan ocean basin began to be subducted towards the northeast, thus causing the basin to be split and expand again, and then the basin developed into the stage of the back -arc basin. At the end of the Indosinian period, the basin gradually closed from east to west, | Zeng Yunfu, Liu Wenjun, Cheng Hongde, Zheng Rongcai, Zhang Jinquan Chengdu Institute of Technology, Chengdu, SichuanLi Xiaoquan and Jiang Tingcao Regional Geological Survey Party of Guangxi,Guilin,Guangxi Jiang M inxi | 1995 | Acta Geologica Sinica(English Edition)1995，69，4： | 18 |
| 3 | The record of paleoclimatic change from stalagmites and the determination of termination II in the south of Guizhou Province, China显示文摘A high-resolution climate record from 163.00 kaBP to 113.80 kaBP has been obtained through TIMS-U series dating and carbon and oxygen isotope analysis of the three large stalagmites from two caves in the south of Guizhou Province, China. The record of the oxygen isotopes from the stalagmites reveals that the undulation characteristics between the cooling event of the glacial period and the warming event of the interglacial period in the research area can compare well to those of ice cores, lake sediments, loess and deep sea sediments on the scale of ten-thousand years or millennium time scale. The climate undulation provided by the record of the stalagmites has a coherence with the global changes and a tele-connection to the paleoclimate changes in the north polar region. Our results suggest that the direct dynamics of paleo-monsoon circulation changes reflected in the record of the stalagmites might be caused by changes of the global ice volume, and in turn related to various factors, including the solar radiation strength at the mid-latitudes in the Northern Hemisphere, the southern extension of the ice-rafted event in the North Atlantic, and changes of the equatorial Pacific sea surface temperature at the low-latitudes. Using δ18O values, we have calculated the temperatures and the results show that the temperature difference between the penultimate glacial period (with an average temperature of 8.1℃, and a minimum temperature range from 0.65℃ to -1.43℃ at stage 6 ) and the last interglacial period (with an average temperature of 18.24℃ at sub-stage 5e ) was about 10℃. This temperature difference from the record of the stalagmites corresponds in general to the record temperature variation (about 10℃) of measured ice cores. The climate records from the three stalagmites in the two caves have shown that the circulation strength of the Asian summer monsoon and the winter monsoon in the penultimate glacial period and the last interglacial period had a clear change. With the TIMS-U series method, termination II of the penultimate glacial period has been precisely dated at an age of (129.28±1.10) kaBP for the three stalagmites in the south of Guizhou Province, China. This borderline age represents the beginning of the last interglacial period or the boundary between the Middle Pleistocene and the Late Pleistocene, and corresponds to the beginning age of the last interglacial period shown by the ice cores and in the SPECMAP curve of the marine oxygen isotopes. The chronology determination of termination II is not only of stratigraphic and chronological significance, but also lays an important foundation for discussing the short time scales of climate oscillation and rapidly changing events of paleoclimate in the circulation region of the East Asian monsoon. | ZHANG Meiliang, YUAN Daoxian1, LIN Yushi, CHENG Hai, QIN Jiaming &ZHANG HuilingKarst Dynamics Laboratory, Institute of Karst Geology, Chinese Academy of Geological Sciences, Guilin 541004, China Geography Department, Minnesota University, MN 55455, USA Correspondence should be addressed to Zhang Meiliang | 2004 | Science China Earth Sciences2004，47，1： | 9 |

| 10 | STGI:a spatio-temporal grid index model for marine big data显示文摘Marine big data are characterized by a large amount and complex structures,which bring great challenges to data management and retrieval.Based on the GeoSOT Grid Code and the composite index structure of the MongoDB database,this paper proposes a spatio-temporal grid index model(STGI)for efficient optimized query of marine big data.A spatio-temporal secondary index is created on the spatial code and time code columns to build a composite index in the MongoDB database used for the storage of massive marine data.Multiple comparative experiments demonstrate that the retrieval efficiency adopting the STGI approach is increased by more than two to three times compared with other index models.Through theoretical analysis and experimental verification,the conclusion could be achieved that the STGI model is quite suitable for retrieving large-scale spatial data with low time frequency,such as marine big data. | Tengteng Qu Lizhe Wang Jian Yu Jining Yan Guilin Xu Meng Li Chengqi Cheng Kaihua Hou Bo Chen | 2020 | Big Earth Data2020，4，4： | 1 |

| 12 | Evaluation of the protective effect of salidroside on arsenic-induced cardiac dysfunction in rats显示文摘Arsenic is a natural metal found in nature.Excessive intake of arsenic in the human body can lead to acute and chronic arsenic poisoning and even induce various diseases,such as cancers[1].According to statistics,approximately 200 million people worldwide are exposed to the toxic effects of arsenic[2].Previous studies showed that in the case of arsenic poisoning,arsenic could induce cells to produce excessive reactive oxygen species(ROs)through oxidative stress pathways,promote inflammatory reactions,and cause myocardial cell damage,leading to dysfunction of the heart[3,4].Salidroside(Sal)has been proven to have various pharmacological activities,such as anti-inflammatory,antioxidant,anticancer,antimetabolic disorders,and neuroprotective effects[5].In recent years,the cardiovascular protective effect of Sal has received attention and has been used to treat various cardiovascular diseases[6]. | Ruimeng Tian Jing Cheng Yanna Wang Chuncui Chen Lei Huang Caiyun Zhang Yifei Zhou Shanshan Dong Guilin Lu Wenjuan Qin | 2024 | Acta Biochimica et Biophysica Sinica2024，56，1： | 0 |

| 16 | Stress compensation based on interfacial nanostructures for stable perovskite solar cells显示文摘The long-term stability issue of halide perovskite solar cells hinders their commercialization.The residual stress-strain affects device stability,which is derived from the mismatched thermophysical and mechanical properties between adjacent layers.In this work,we introduced the Rb_(2)CO_(3)layer at the interface of SnO_(2)/perovskite with the hierarchy morphology of snowflake-like microislands and dendritic nanostructures.With a suitable thermal expansion coefficient,the Rb_(2)CO_(3)layer benefits the interfacial stress relaxation and results in a compressive stress-strain in the perovskite layer.Moreover,reduced nonradiative recombination losses and optimized band alignment were achieved.An enhancement of open-circuit voltage from 1.087 to 1.153 V in the resultant device was witnessed,which led to power conversion efficiency(PCE)of 22.7%(active area of 0.08313 cm^(2))and 20.6%(1 cm2).Moreover,these devices retained 95%of its initial PCE under the maximum power point tracking(MPPT)after 2700 h.It suggests inorganic materials with high thermal expansion coefficients and specific nanostructures are promising candidates to optimize interfacial mechanics,which improves the operational stability of perovskite cells. | Cheng Zhu Xi Wang Hangxuan Li Chenyue Wang Ziyan Gao Pengxiang Zhang Xiuxiu Niu Nengxu Li Zipeng Xu Zhenhuang Su Yihua Chen Huachao Zai Haipeng Xie Yizhou Zhao Ning Yang Guilin Liu Xueyun Wang Huanping Zhou Jiawang Hong Xingyu Gao Yang Bai Qi Chen | 2023 | Interdisciplinary Materials2023，2，2： | 0 |

| 18 | Assessment of the alleviating effects of salidroside on myocardial function and perfusion impairment in rats with sepsis显示文摘Sepsis is a systemic inflammatory response syndrome caused by infection that affects millions of people each year and carries a high risk of death.It has become a global public health problem[1].Sepsis mediates mitochondrial dysfunction,inhibits myocardial function,and directly causes impaired myocardial circulation.When septic cardiac dysfunction occurs,the mortality rate of patients with sepsis increases significantly[2].Salidroside,extracted from the Chinese herb Rhodiola rosea,is a phenolic chemical.Zhao et al.[3]found that salidroside has good biological activity against various cardiovascular diseases.These effects include reducing myocardial injury,enhancing myocardial contractility and improving myocardial perfusion,thus promoting recovery of cardiac function[4].In this study,we aimed to investigate the protective effect of salidroside on septic cardiotoxicity in rats. | Wenjuan Qin Wenrong Shi Ruimeng Tian Yanna Wang Jia Feng Yifei Zhou Shanshan Dong Jing Cheng Caiyun Zhang Guilin Lu | 2023 | Acta Biochimica et Biophysica Sinica2023，55，5： | 0 |
