| 1 | Aqueous Chemistry of Typical Geothermal Springs with Deep Faults in Xinyi and Fengshun in Guangdong Province,China显示文摘This paper investigated aqueous chemistry for two geothermal spring groups responsive and sensitive to flow fluctuations induced by earthquakes. Quake monitorings are favored for their being in residential areas with well-preserved natural flow systems in Xinyi City's Xijiang Hot Springs and Fengshun County's Shihu Hot Spring. The hot springs are typical in temperatures and flow rates in southern China's Guangdong Province. Physical and chemical conditions deep down in the heat sources are important constraints on earthquake,fluid flow,reactive solute transport and heat transfer,but remain challenging to address via field observations and numerical experiments. In this paper,we made daily and annual observations on flow rates,temperature,and/or aqueous chemistry. We employed strontium isotopes as tracers for the water sources,equilibrium phase diagram for K-feldspar and albite stability,and Na-K-Mg diagram for heat reservoir temperatures. The abundant sulfite content in Xi- jiang Hot Springs is discussed. Our main finding are that the deep fault springs are characterized by low reduction-oxidation potential at around-200–-150 m V and relatively large daily flow variations. The results provide scientific background features on the field sites regarding earthquake monitoring and predictions and geothermal reservoir. | Guoping Lu Runfang Liu | 2015 | Journal of Earth Science2015，26，1： | 10 |
| 2 | RNA-Seq analysis and development of SSR and KASP markers in lentil(Lens culinaris Medikus subsp. culinaris)显示文摘Lentil(Lens culinaris Medikus subsp.culinaris,2 n=14)is a cool-season legume with high production potential for multiple uses.However,limited molecular research has been conducted in this species owing to its large genome,which impedes the generation of genome sequences and the development of molecular markers.In this study,more than 1.37 billion filtered clean reads were collected by RNA-Seq of six diverse lentil accessions and217,836 transcripts and 161,095 unigenes were de novo assembled,yielding respectively 257.1 and 240.6 million nucleotides.The mean transcript length was 1180 bp and the N50 and N90 lengths were respectively 2075 and 479 bp.The mean length of the unigenes was 1494 bp and their N50 and N90 values were respectively 2203 and 714 bp.The unigenes were annotated against seven databases.The FLOWERING LOCUS T(FT)gene homolog in lentil showed high protein sequence similarity to the FT gene homologs of pea and alfalfa.On the basis of the RNA-Seq analysis,26,449 EST-SSR markers were designed in silico,and 276 preliminarily screened markers were selected to evaluate polymorphism in 94 diverse lentil accessions.In total,125(45.29%)of 276 EST-SSR markers were found to be polymorphic.A total of 130,073 SNP loci were detected and 78(61.41%)of 127 SNPs were successfully converted to KASP markers.Population genetic analyses of the lentil accessions with EST-SSR and KASP markers revealed similar genetic structures,suggesting that the RNA-Seq-generated resources and the developed markers are reliable for use in molecular marker-assisted breeding of lentil. | Dong Wang Tao Yang Rong Liu Nana Li Xiaomu Wang Ashutosh Sarker Xiaodong Zhang Runfang Li Yanyan Pu Guan Li Yuning Huang Yishan Ji Zhaojun Li Qian Tian Xuxiao Zong Hanfeng Ding | 2020 | The Crop Journal2020，8，6： | 1 |
| 3 | Integrated representation of geospatial data,model,and knowledge for digital twin railway显示文摘The real-time accurate description of all spatial features of railway and their spatiotemporal relationships is a crucial factor in realizing comprehensive management and related decision-making within the entire life cycle of railways.Nevertheless,available spatiotemporal data models mainly use static historical sequence data,which are insufficient to support multi-source heterogeneous real-time sensed data;they lack a systematic depiction of the interactive relationships among multiple feature entities,and are limited to low-level descriptive analysis.Therefore,this study proposes a data-model-knowledge integrated representation data model for a digital twin railway,which explicitly describes the spatiotemporal,and interaction relationships among railway features through a conceptual knowledge graph.This study first analyzes the characteristics of railway features from above ground to underground,and then constructs a conceptual model to clearly describe the complex relationships among railway features.Secondly,a logical model is developed to illustrate the basic data structure.Thirdly,an ontology model is constructed as a basic framework for further deepening the domain knowledge graph.Finally,considering the prevention of landslides as an example,it demonstrates the abundant spatiotemporal relationships among railway related features.The results of this study bring more clear understanding of the complex interactive relationships of railway entities. | Hankan Li Qing Zhu Liguo Zhang Yulin Ding Yongxin Guo Haoyu Wu Qiang Wang Runfang Zhou Mingwei Liu Yan Zhou | 2022 | International Journal of Digital Earth2022，15，1： | 1 |
| 4 | Establishment and Operation of Crop Genebank in Shandong Province显示文摘Shandong Province has abundant and diverse crop germplasm resources, but it is in lack of unified and effective preservation and management, leading to the decline and even extinction of many rare germplasm resources. In this study, the necessity for the establishment of crop genebank in Shandong Province was briefly described. In addition, the type, functions and technical indicators, as well as the operation of the crop genebank were introduced comprehensively to provide a reference for the establishment of genebank by other units or organizations. | Dong WANG Runfang LI Shihua LIU Cun'e WANG Lingyun LU Nana LI Hanfeng DING Xiaomu WANG Xiaohong GU Yingjie LIN Xiaodong ZHANG | 2017 | Agricultural Science & Technology2017，18，11： | 0 |
