Abstract: In a creation method of a trained model, a reconstructed image (60) obtained by reconstructing three-dimensional X-ray image data (80) is generated. A projection image (61) is generated from a three-dimensional model of an image element (50) by a simulation. The projection image is superimposed on the reconstructed image to generate a superimposed image (67). A trained model (40) is created by performing machine learning using the superimposed image, and the reconstructed image or the projection image.

Abstract: A moving turbine blade is disclosed. When an angle, which a tangent to a dorsal surface portion at a front edge of the moving turbine blade makes with a straight line perpendicular to a rotating shaft of a turbine, is designated as &thgr;, and a geometrical outlet angle of a stationary blade is designated as &agr;n, &thgr; is in the relationship &agr;N+2°<&thgr;<&agr;N+12°. As a result, the shape of the dorsal surface portion, at the front edge and in a portion adjacent thereto, of the moving turbine blade is not parallel to a stationary blade wake. Thus, the moving turbine blade can contribute to increasing the efficiency of the turbine, while suppressing an unsteady sharp increase in flow velocity.
