The ACE-CRIS data are extracted from the ACE Science Center2) ，adopting the same observational period as that of AMS-02（from May 19，2011 to May 26，2016）.The systematical uncertainties of the flux measurements come from the geometry factor（2%），the scintillating optical fiber trajectory efficiency（2%），and the correction for spallation in the instrument（～1%-5%）[34].The total uncertainties are obtained through quadratically adding the statistical ones and the systematical ones together[34].Since the energy ranges of boron and carbon nuclei are different，their fluxes are interpolated to common energy grids as in ref.[34].The ACE-CRIS data about the B/C ratio，the carbon and oxygen fluxes are give in Tables 1 and 2.
