摘　　要：The discrepancies that if there is any amphidromic point of S2 constituent and its location if there is around the Natuna Islands in the southern South China Sea have suspended for a long time, however, there is always no convincing research to settle them up to now. The TOPEX/Poseidon and Jason-1 altimeters have been providing a long-term sea surface height data, which can be used to calculate the constants of tidal constituents along the satellite footprint with the harmonic analysis method. Based on more than 12 years altimetry data from T/P and Jason-1, the character of phase lags from harmonic analysis is used to identify if there is a S2 am-phidromic point around the Natuna Islands. The result shows that there is no S2 amphidromic point instead of a nodal line of a standing wave, and the amplitude of S2 constituent is close to zero along the nodal line.The discrepancies that if there is any amphidromic point of S2 constituent and its location if there is around the Natuna Islands in the southem South China Sea have suspended for a long time, however, there is always no convincing research to settle them up to now.
