摘　　要：A remarkable inconsistency between the calibrated differential time-ordered data (TOD) of the Wilkinson Microwave Anisotropy Probe (WMAP) mission,which is the input for map-making,and the cosmic microwave background (CMB) temperature maps published by the WMAP team is revealed,indicating that there must exist a serious problem in the map making routine of the WMAP team.This inconsistency is easy to be confirmed without the use of WMAP map-making software.In view of the importance of this issue for cosmology study,we invite readers to check it by themselves.A remarkable inconsistency between the calibrated differential time-ordered data （TOD） of the Wilkinson Microwave Anisotropy Probe （WMAP） mission, which is the input for map-making, and the cosmic microwave background （CMB） temperature maps published by the WMAP team is revealed, indicating that there must exist a serious problem in the map making routine of the WMAP team.
