| 1 | SCC Behaviour of X-70 Pipeline Steel in Near-Neutral pH Solutions显示文摘The stress corrosion cracking (SCC) behaviour of X-70 pipeline steel in near-neutral pH solutions was studied via slow strain rate testing (SSRT). The results showed that the cracking mode of X-70 pipeline steel in near-neutral pH solutions was transgranular at different temperatures and applied potentials with the feature of quasi-cleavage. The pH value of the solution decreased with increasing the addition of CO2, which increased the susceptibility to SCC.SCC susceptibility increased as the applied potential moved towards the cathodic direction, suggesting that hydrogen induced cracking (HIC) dominated the cracking process at cathodic potentials. The slight decrease of pH values with decreasing temperature of the solution increased the susceptibility to SCC, which attributed to the change of solubility of CO2 in the solution at different temperatures. The propagating directions of SCC cracks were different at different potentials. At rather negative cathodic potentials, the cracks were almost perpendicular to the tensile axis, while at free corrosion potential and near anodic potentials, cracks were nearly at 45 degree, and in the range of moderate cathodic potentials both propagating directions could be observed. | HaoGUO GuangfuLI XunCAI JianjiangZHOU WuYANG | 2005 | Journal of Materials Science & Technology2005，21，1： | 2 |
| 2 | Modeling the ocean circulation in the Bering Sea显示文摘With parameterized wave mixing,the circulation and the tidal current in the Bering Sea were simulated simultaneously using the three-dimensional Princeton Ocean Model.The simulated circulation pattern in the deep basin is relatively stable, cyclonic,and has little seasonal change.The Bering Slope Current between 200-1000 m isobaths was estimated to be 5 Sv in volume transport.The Kamchatka Current was estimated to be 20 Sv off the Kamchatka Peninsula.The Bering shelf circulations vary with season,driven mainly by wind.These features are consistent with historical estimates .A counter current was captured flowing southeastward approximately along the 200 m isobath of the Bering Slope,opposite to the northwestward Bering Slope Current ,which needs to be validated by observations.An upwelling current is located in the shelf break(120-1000 m) area,which may imply the vertical advection of nutrients for supporting the Bering Sea Green Belt seasonal plankton blooms in the break-slope area.The Bering Slope Current is located in a downwelling area. | Hu Haoguo Wang Jia | 2008 | Chinese Journal of Polar Science2008，19，2： | 1 |

| 6 | Observations and modeling of the ice-ocean conditions in the coastal Chukchi and Beaufort Seas显示文摘The Chukchi and Beaufort Seas include several important hydrological features:inflow of the Pacific water,Alaska coast current(ACC),the seasonal to perennial sea ice cover,and landfast ice along the Alaskan coast.The dynamics of this coupled ice-ocean system is important for both regional scale oceanography and large-scale global climate change research.A number of moorings were deployed in the area by JAMSTEC since 1992,and the data revealed highly variable characteristics of the hydrological environment.A regional high-resolution coupled ice-ocean model of the Chukchi and Beaufort Seas was established to simulate the ice-ocean environment and unique seasonal landfast ice in the coastal Beaufort Sea.The model results reproduced the Beaufort gyre and the ACC.The depth-averaged annual mean ocean currents along the Beaufort Sea coast and shelf break compared well with data from four moored ADCPs,but the simulated velocity had smaller standard deviations,which indicate small-scale eddies were frequent in the region.The model results captured the seasonal variations of sea ice area as compared with remote sensing data,and the simulated sea ice velocity showed an almost stationary area along the Beaufort Sea coast that was similar to the observed landfast ice extent.It is the combined effects of the weak oceanic current near the coast,a prevailing wind with an onshore component,the opposite direction of the ocean current,and the blocking by the coastline that make the Beaufort Sea coastal areas prone to the formation of landfast ice. | JIN Meibing WANG Jia MIZOBATA Kohei HU Haoguo SHIMADA Koji | 2008 | Acta Oceanologica Sinica2008，27，3： | 1 |

| 8 | A classification method of building structures based on multi-feature fusion of UAV remote sensing images显示文摘In order to improve the accuracy of building structure identification using remote sensing images,a building structure classification method based on multi-feature fusion of UAV remote sensing image is proposed in this paper.Three identification approaches of remote sensing images are integrated in this method:object-oriented,texture feature,and digital elevation based on DSM and DEM.So RGB threshold classification method is used to classify the identification results.The accuracy of building structure classification based on each feature and the multi-feature fusion are compared and analyzed.The results show that the building structure classification method is feasible and can accurately identify the structures in large-area remote sensing images. | Haoguo Du Yanbo Cao Fanghao Zhang Jiangli Lv Shurong Deng Yongkun Lu Shifang He Yuanshuo Zhang Qinkun Yu | 2021 | Earthquake Research Advances2021，1，4： | 0 |
| 9 | Modeling seasonal variations of ocean and sea ice circulation in the Beaufort and Chukchi Seas:A model-data fusion study显示文摘A 3.8-km Coupled Ice-Ocean Model(CIOM) was implemented to successfully reproduce many observed phenomena in the Beaufort and Chukchi seas,including the Bering-inflow-originated coastal current that splits into three branches: Alaska Coastal Water(ACW),Central Channel,and Herald Valley branches.Other modeled phenomena include the Beaufort Slope Current(BSC),the Beaufort Gyre, the East Siberian Current(ESC),mesoscale eddies,seasonal landfast ice,sea ice ridging,shear,and deformation.Many of these downscaling processes can only be captured by using a high-resolution CIOM,nested in a global climate model.The seasonal cycles for sea ice concentration,thickness,velocity,and other variables are well reproduced with solid validation by satellite measurements.The seasonal cycles for upper ocean dynamics and thermodynamics are also well reproduced,which include the formation of the cold saline layer due to the injection of salt during sea ice formation,the BSC,and the subsurface upwelling in winter that brings up warm,even more saline Atlantic Water along the shelfbreak and shelf along the Beaufort coast. | Wang Jia Kohei Mizobata Hu Haoguo Jin Meibing Zhang Sheng Walter John-son Koji Shimada Moto Ikeda | 2008 | Chinese Journal of Polar Science2008，19，2： | 0 |
