Methods for processing depression and flat areas in extracting drainage networks based on the DEM;

Reservoir space characters of Late Jurassic-Early Cretaceous volcanic rocks from Shengping area of Songliao Basin and their affecting factors;

Based on the observation and study of a large number of cores and thin sections by cathodoluminescence and SEM, this paper expounds in detail the mechanism of the main diagenesis and its action mode and analyzes the diagenesis sequences and porosity evolution of the Permian Pingdiquan Formation in WucaiwanShishugou region of the eastern Junggar Basin.

Associated with the study of lighter hydrocarbon constituent, carbon isotope, biomarker and inclusions, adopted the technique of oil source correlation on whole oil samples, it can be confirmed that the hydrocarbon source of viscous crude in Permian, in the east slope of Jimusaer depression, is Pingdiquan Formation mudstone; Carboniferous oil comes from Carboniferous source rock.

Design of flatland type concentrator for Hanxing iron mine;

),the human knee joint model including femur,tibia,fibula,patella,four main ligaments and muscles was systematically established and used to simulate the dynamic response of the human normal gait in level walking and the influence of the deficiency of anterior cruciate ligament(ACL) on the knee joint contact forces.
