To make it clear, we propose the method of Fourier series expansion of the matter profile. By using this method, we can take account of both the matter profile effect and its ambiguity. For very long baseline experiment, such as L = 7332 km, in the analysis of the oscillation phenomena we need to introduce a new parameter a(1)-the Fourier coefficient of the matter profile-as a theoretical parameter to deal with the matter profile effects., Copyright notice(c)2001 American Physical Society.
