    "abstract": "Due to the phase interference of electromagnetic wave, one can recover the\ntotal image of one object from a small piece of holograph, which records the\ninterference pattern of two laser light reflected from it. Similarly, the\nquantum superposition principle allows us to derive the global phase diagram of\nquantum spin models by investigating a proper local measurement. In the present\npaper, we study the two-site entanglement in the antifferomagnetic spin models\nwith both spin-1/2 and 1. We show that its behaviors reveal some important\ninformation on the global properties and the quantum phase transition of these\nsystems.",
