Abstract

The disturbance amplitude of ion line spectra can reach 1~600 in the heating experiment, and the enhancement structure almost continues all the heating time, which can´t be explained by parameter instability, though it can give an explanation for enhancement structure qualitatively in very short time. Almost all the abnormity spectra structure are double-humped anisomerous composed by coherent echo single-humped and incoherent echo double-humped. Through extracting and dealing with the coherent structure, we get the coherent echo single-humped, and find that the coherent echo is dominating.
