The continental margin in the Bellingshausen Basin off West Antarctica was geologically and geophysically surveyed.The paleo-trench, which has been inferred from the seafloor magnetic anomalies, is found out in the 3-fold seismic reflection profiles.In addition, the paleo-trench-lower-slope-sedimentary-complex on the oceanic basement, sediments DUC
The catch-words of DUCKBILL CLIP Russian politicians that Russia will be plunged into a severe economic depression if GDP is not being doubled at any price are the truth just in part in the judgment of the author.Firstly, the social problems of indigence and problems of pollution of the environment should be settled rapidly as having the top priori
In order to improve the accuracy of shield tunneling parameter matching under the limited data, the matching model based on support vector machine (SVM) and exponential adjustment inertia weight immune particle swarm optimization (EAIW-IPSO) is proposed.The nonlinear relationship model between the tunneling parameters and the Hair Brush ground sett
