Turbine moving blade

The turbine moving blade comprises a blade body, the blade body is formed by stacking and twisting a plurality of basic two-dimensional blade profiles, each basic two-dimensional blade profile comprises a basic two-dimensional blade profile section, and the basic two-dimensional blade profile section has parameters including the total blade height H and the relative pitch; the change rule of the relative pitch of the basic two-dimensional blade profile section is that the relative pitch of the basic two-dimensional blade profile section is gradually increased from the root section to the middle section in the blade total height H direction, and the relative pitch of the basic two-dimensional blade profile section is gradually decreased from the middle section to the top section. According to the blade body height, the change rule of the outlet geometric angle and the relative pitch in the blade height direction is determined, so that the steam leakage amount of the blade top area is reduced, the inlet and out
