摘要：

A nonlinear ballooning mode formulation in general magnetic coordinates is developed for the cold ion electrostatic drift wave problem in stellarators. It is shown that local ripple shear, not global average shear, radially localizes microturbulent modes which are located along the field lines by local ripple curvature wells. It is argued that microturbulence in stellarators depends dominantly on local ripple shear and curvature and may be rather insensitive to global (or average) shear and curvature.
