Other AbstractA typical substorm p rocess in t he night-side near-Eart h magnetotail company wit h t he pile-up and depolarization p rocess explored by TC-1 on sep 17,2004.We analyzed t he FGM and HIA data (4s resolutio n) wit h wavelet and FFT analysis met hod to under stand t he low-f requency wave in t he pile-up and dipolarization p rocess.The analysis result s showed t hat t here are distinctly irregular low-f requency wave in t he pile-up and dipolarizatio n p rocess,t he main range of t he wave f requency is 4-15 mHz , coincident wit h t he Pi22 p ul se. The L F wave of t he each magnetic field component in t he dipoarization p rocess is distinctly different wit h t hat in t he pile-up p rocess. During t he pileup and dipolarization p rocess,t he wave of t he temperat ure and velocity in t he direction parallel to t he magnetic field is distinctly wit h t hat in t he directio n perpendicular to the magnetic field. It seems t he wave of t he temperat ure and velocity in t he direction parallel to t he magnetic field has good correlation,and t he wave of t he ions density has good correlation wit h t he wave in t he direction parallel to t he magnetic field ,which means t here exist comp ressive wave in t he direction parallel t he magnetic field. The exploration by t he TC-1 showed that there are distinct increase of t he B y component in t he pile-up p rocess.The UL F wave has clo sely correlation wit h increase By component,and may has important effect of t he substorm onset.
