A method is proposed to prepare an effective pure state corresponding to the pure state $|0\rangle$ $|0\rangle$ $\cdots|0\rangle$ for any number of spins on a nuclear magnetic resonance quantum computer, where $|0\rangle$ stands for the spin-up state of a nuclear spin.The method is based on the spatial labeling proposed by Cory et al.
