Summary:According to the magnetic resonance spectrum fitting method and system and the terminal, the real part data of the frequency domain spectrum is obtained by performing Fourier transform on the collected spectrum data, the limited frequency range of the interested spectrum is selected, the frequency coordinate index data relative to the whole spectrum is determined, and the corresponding limited spectrum is generated from the real part data; based on the set spectrum baseline extension value and the frequency coordinate index data, performing frequency extension on the limited spectrum, setting the sampling interval time and the acquisition point number of a time domain and frequency domain spectrum fitting function, and finally fitting the extended spectrum. According to the method, the time-domain and frequency-domain spectrum fitting function is constructed by using the sampling interval time which is the same as the acquired data, so that the minimization of a base line is ensured; before fitting, artificia
