| 10 | Geological conditions, reservoir evolution and favorable exploration directions of marine ultra-deep oil and gas in China显示文摘By analyzing the structural background,petroleum geological conditions,and typical regional(paleo) oil and gas reservoirs in marine ultra-deep oil and gas regions in China,this paper reveals the evolution processes of the marine ultra-deep oil and gas reservoirs and the key controlling factors of accumulation.The marine ultra-deep oil and gas resources in China are buried at depth of greater than 6000 m,and are mainly distributed in the Precambrian and Lower Paleozoic strata in the Sichuan,Tarim and Ordos cratonic basins.The development of marine ultra-deep source rocks in China is controlled by cratonic rifts and cratonic depressions with the background of global supercontinent breakup-convergence cycles.The source rocks in Sichuan Basin have the most developed strata,followed by Tarim Basin,and the development strata and scale of Ordos Basin needs to be further confirmed.The marine ultra-deep reservoir in China is dominated by carbonate rocks,and the reservoir performance is controlled by high-energy sedimentary environment in the early stage,superimposed corrosion and fracture in the later stage.The regional caprocks are dominated by gypsum salt rocks,shale,and tight carbonate rock.The ultra-deep oil and gas fields in China have generally experienced two stages of oil-reservoir forming,cracking(or partial cracking) of paleo-oil reservoirs,and late finalization of cracked gas(or highly mature to over mature oil and gas).The oil and gas accumulation is controlled by static and dynamic geological elements jointly.Major hydrocarbon generation center,high quality and large-scale reservoir resulted from karstification of high energy facies belt,thick gypsum rock or shale caprock,and stable trapping and preservation conditions are the key factors for accumulation of ultra-deep oil and gas.We propose three favorable exploration directions,i.e.the areas around intracratonic rift and intracratonic depression,and craton margin. | LI Jianzhong TAO Xiaowan BAI Bin HUANG Shipeng JIANG Qingchun ZHAO Zhenyu CHEN Yanyan MA Debo ZHANG Liping LI Ningxi SONG Wei | 2021 | Petroleum Exploration and Development2021，48，1： | 0 |
| 11 | Drought Tolerance Identification and Eevluation of Maize during Flowering Stage in Guangxi显示文摘Total 20 maize varieties were subjected to drought stress at flowering stage,and then the relative water content,soluble sugar content,chlorophyll content,malondialdehyde( MDA) content and superoxide dismutase( SOD) activity in their leaves,as well as their yields were determined. The drought tolerance of the physiological and biochemical indexes was scored by five-level scoring method,and the drought tolerance index was calculated by the yield index to comprehensively evaluate the drought tolerance of maize during flowering stage. The results showed that the scores of drought tolerance of the maize varieties ranged from 1. 929 3 to 5. 659 5. Among them,the scores of Zhengda 619,Guidan 162 and Guidan 0810 were greater than 5. 0,followed by Dika 008,Xianyu 30 T60,Xianzhengda 901,Qingnong 68,South America No. 1 and Wanchuan 1306 of which the scores were in the range of 4. 0-5. 0. The drought tolerance indexes were in the range of 0. 410 4-1. 096 3. Among the test maize varieties,the drought tolerance indexes of Guidan 0810,Pacific 99 and Zhengda 619 were greater than 1. 0,and those of Xianyu 30 T60,Dika 008 and South America No. 1 were in the range of 0. 9-1. 0. The correlation between the two kinds of evaluation results was 0. 588 7 and was extremely significant. The five-level scoring method and the drought tolerance index can be used simultaneously for the evaluation of drought tolerance of maize during flowering stage. The two aspects of evaluation results showed that Guidan 0810,Zhengda 619,Xianyu 30 T60,Dika 008 and South America No. 1 were drought-tolerant varieties,among which Guidan 0810 and Zhengda 619 were extremely highly drought-tolerant varieties. | Chenglin ZOU Hua TAN Debo ZHENG Ruining ZHAI Aihua HUANG Runxiu MO Xinxing WEI Kaijian HUANG | 2019 | Asian Agricultural Research2019，11，6： | 0 |
| 12 | Effect of Foliar Application of Selenium Fertilizer on Yield,Selenium Content and Heavy Metal Contents of Waxy Maize显示文摘[Objectives]This study aimed to explore the effect of different concentrations of selenium fertilizer on the yield,selenium content and heavy metal contents of waxy maize,thereby providing reference for the scientific application of selenium fertilizer on waxy maize.[Methods]Different varieties of waxy maize(Guitiannuo 611,Guinuo 615 and Guiheinuo 609)were used as test materials.They were sprayed with different concentrations(0,0.5,1.0,1.5 and 2.0 g/L)of water-soluble selenium fertilizer(Xinxibao)at the big flare stage,and the effect on the yield,selenium content and heavy metal contents of the waxy maize was analyzed.[Results]Foliar application of different concentrations of selenium fertilizer showed no significant effect on the yield and yield components of waxy maize.As the concentration of selenium fertilizer increased,the grain selenium content of different varieties of waxy maize increased.Among them,the increase of Guinuo 615 was the largest,of which the selenium content reached 0.265 mg/kg,2.82 times that of the control(water).The cadmium and arsenic contents of different varieties of waxy maize decreased with the increase of the concentration of selenium fertilizer sprayed.Among the waxy maize varieties,the cadmium and arsenic contents of Guitiannuo 611 dropped the most significantly,up to 52.94%and 77.78%.In waxy maize,the correlation coefficients between selenium content and cadmium,arsenic contents were-0.5509(P<0.05)and-0.8530(P<0.01),respectively.[Conclusions]Spraying exogenous selenium fertilizer had no obvious effect on the yield of waxy maize.However,the increase of the concentration of exogenous selenium fertilizer could significantly increase the selenium content and reduce the cadmium and arsenic contents in grains of different varieties of waxy maize. | Chenglin ZOU Ruining ZHAI Kaijian HUANG Hua TAN Debo ZHENG Aihua HUANG Xinxing WEI Runxiu MO Faqian XIONG Hui WEI Shanzhu WEI | 2020 | Asian Agricultural Research2020，12，8： | 0 |
| 13 | Effect of Drought Stress on Proteome of Maize Grain during Grain Filling显示文摘Based on isobaric tags for relative and absolute quantification(iTRAQ)technology,the proteome of grains of a maize cultivar Huangzao 4 under drought stress at grain filling stage was analyzed.The results show that under drought stress,438 proteins were differentially expressed in the maize grains during grain filling.Among them,200 were up-regulated and 238 were down-regulated.The gene ontology(GO)analysis shows that the biological processes in which differential proteins are more involved are cellular processes,metabolic processes and single biological processes;proteins in the cell component category are mainly distributed in cells,cell parts and organelles;and the proteins the molecular function category mainly possess catalytic activity and binding function.Differentially expressed proteins classified by COG are mainly involved in protein post-translational modification and transport,molecular chaperones,general functional genes,translation,ribosomal structure,biosynthesis,energy production and transformation,carbohydrate transport and metabolism,amino acid transport and metabolism,etc.The subcellular structure of the differentially expressed proteins is mainly located in the cell chloroplast and cytosol.The proportions are 35.01%and 30.21%respectively.KEGG metabolic pathway enrichment analysis shows that the differentially expressed proteins are mostly involved in antibiotic biosynthesis,microbial metabolism in different environments,and endoplasmic reticulum protein processing;the metabolic pathways with higher enrichment are the carbon fixation pathway and estrogen signaling pathway of prokaryotes;and the higher enrichment and greater significance are in the tricarboxylic acid cycle,carbon fixation of photosynthetic organisms and proteasome.The results of this study preliminarily reveal the adaptive mechanism of maize grains in response to drought stress during grain filling,providing a theoretical reference for maize drought-resistant molecular breeding. | Chenglin ZOU Debo ZHENG Hua TAN Kaijian HUANG Aihua HUANG Xinxing WEI Runxiu MO Ruining ZHAI | 2021 | Asian Agricultural Research2021，13，1： | 0 |
| 14 | Study on the Distribution of Frictional Forces on Z-yarn Continuous Implanted Preforms and Their Applications显示文摘To improve the quality and efciency of Z-directional 3D preform forming,the Z-yarn frictional force distribution model of the preform and its wear mechanism were investigated.In this study,a tensile force measuring device was designed to measure the force required to replace the guide sleeve,which is equivalent to the Z-yarn frictional forces.The frictional force is proportional to the number of preform layers and is applied to the preform decreased from the corner,edge,sub-edge,and middle in order.A back propagation neural network model was established to predict the friction at diferent positions of the preform with diferent layers,and the error was within 1.9%.The wear of Z-yarn was studied at diferent frictional positions and after diferent times of successive implantation into the preform.The results showed that with an increase in the number of Z-yarn implantations and frictional forces,the amount of carbon fber bundle hairiness gradually increased,and the tensile fracture strength damage of the fber was increasingly afected by the frictional forces.In the corner position of the preform,when the number of implantations was 25,the fber fracture strength decreased non-linearly and substantially;in order to avoid fber fracturing in the implantation process,the Z-yarn needs to be replaced in time after 20–25 cycles of continuous implantation.This study solves the problem of difculty in measuring the force required for individual replacements owing to the excessive number of guide sleeves,puts forward the relationship between fber wear,preform position,and implantation times,solves the phenomenon of fracture in the preform during Z-direction fber implantation,and realizes the continuous implantation of fbers. | Zitong Guo Zhongde Shan Jihua Huang Debo Xue | 2022 | Chinese Journal of Mechanical Engineering2022，35，4： | 0 |
