An Evaluation Method for the Roundness Error Based on Curvature;

Study of contact force between drill string and borehole wall in constant-curvature wellbores;

Curvature line and curvature characteristics of developable surface;

The practice of predicting natural fracture zones in deep formation in An Peng oilfield indicates that the extremum main curvity method has definite reliability in predicting pull apart fractures of homogeneous terranes.

The experimental data has proved that the method can be fit for the shaft with small curvity, especially in straightening the axis in auto′s gearbox.

A computing method is presented for studying the bending moment, axial force and curvity relationship at the section of prestressed concrete beam.
