| 1 | UPLC-MS metabolomics provides insights into the diff erences between black- and white-shelled Pacifi c oysters Crassostrea gigas显示文摘A variety of shell colors are one of the most fundamental characteristics of molluscs,which have importantly ecological and economic signifi cance.The Pacifi c oyster Crassostrea gigas is distributed in many sea areas around the world and also an aquacultured mollusc with high nutritional value.In this study,the whole soft body and the mantle tissue of black-shelled Pacifi c oyster(BSO)and white-shelled Pacifi c oyster(WSO)with starkly diff erent melanin contents were compared,and the diff erences in physiology and metabolism between BSO and WSO were analyzed.The results of physiological indicators suggested BSO show more melanin,more dry matter,more crude lipid content,and stronger ability to scavenge free radicals than WSO.The altered metabolites of glycerophospholipids,fatty acyls,and steroids revealed diff erent regulatory mechanisms of lipids.The correlation analysis of metabolomics and previously published RNAseq data suggested that BSO and WSO mainly diff ered in the basal metabolic processes,such as lipid,amino acid and purine metabolisms.This study provides insights into the changes in the physiological indictors and the metabolites of oysters with varying melanin content. | Xi CHEN Qiuyun JIANG Hongce SONG Lingling LI Chaoyi XIE Baoyu HUANG Yaqiong LIU Meiwei ZHANG Lei WEI Xiaotong WANG | 2021 | Journal of Oceanology and Limnology2021，39，1： | 2 |
| 2 | Present Situation of Core Mercury Injection Technology of Unconventional Oil and Gas Reservoir显示文摘Unconventional oil and gas step into a new area of global oil and gas exploration due to the success of the development of shale gas of America.Unconventional tight reservoir has huge differents with conventional reservoirs,including cell aggregation,migration patterns,source configuration storage,reservoir characteristics,flow mechanism and so on,which | GU Meiwei LU Shuangfang XIAO Dianshi GUO Siqi ZHANG Luchuan | 2015 | Acta Geologica Sinica(English Edition)2015，89，A01： | 1 |
| 3 | Prediction of Total Organic Carbon Content Based on Geostatistical Inversion:A Case of Qingshankou Formation in Wangfu Depression,Songliao Basin显示文摘Currently,there are two main methods to obtain total organic carbon(TOC)content in mud shale:geochemical analysis andΔlg R model.Geochemical analysis can obtain accurate TOC content,but it has the problem of higher cost and less samples.TheΔlg R model can obtain TOC content variable values in well profile conveniently and quickly,but it can’t predict TOC content in mud shale in | ZHANG Luchuan LU Shuangfang XIAO Dianshi GUO Siqi GU Meiwei | 2015 | Acta Geologica Sinica(English Edition)2015，89，A01： | 0 |
| 4 | Application of NMR on Quantificational Characterization of Tight Glutenite Reservoirs Pore Size显示文摘Quantificational characterization of the microscopic pore structure is the key to evaluating tight reservoirs.Since tight reservoirs mainly develop nano-pores which are difficult to fully characterize pore throats’distribution by single conventional experimental method,there’s an urgent need to establish a characterization method by jointing several conventional experimental methods.The tight gas of Shahezi Formation in Xujiaweizi | GUO Siqi LU Shuangfang XIAO Dianshi ZHANG Luchuan GU Meiwei | 2015 | Acta Geologica Sinica(English Edition)2015，89，A01： | 0 |
| 5 | Reliability Modeling and Evaluation of Complex Multi-State System Based on Bayesian Networks Considering Fuzzy Dynamic of Faults显示文摘In the traditional reliability evaluation based on the Bayesian method,the failure probability of nodes is usually expressed by the average failure rate within a period of time.Aiming at the shortcomings of traditional Bayesian network reliability evaluation methods,this paper proposes a Bayesian network reliability evaluation method considering dynamics and fuzziness.The fuzzy theory and the dynamic of component failure probability are introduced to construct the dynamic fuzzy set function.Based on the solving characteristics of the dynamic fuzzy set and Bayesian network,the fuzzy dynamic probability and fuzzy dynamic importance degree of the fault state of leaf nodes are solved.Finally,through the dynamic fuzzy reliability analysis of CNC machine tool hydraulic system balance circuit,the application of this method in system reliability evaluation is verified,which provides support for fault diagnosis of CNC machine tools. | Fangjun Zuo Meiwei Jia Guang Wen Huijie Zhang Pingping Liu | 2021 | Computer Modeling in Engineering & Sciences2021，，11： | 0 |
