摘　　要：An entangled state is prepared using nuclear magnetic resonance (NMR). And its attribute is shown in NMR spectra. The relation between quantum entanglement and coherence is discussed by studying the evolution of entangled state under decoherence.An entangled state is prepared using nuclear magnetic resonance (NMR).
