Abstract：
A theoretical method for testing shell effect is proposed. In the framework of the relativistic mean-field theory with the consideration of the BCS approach, by calculating the fluctuation of the particle-number, we discover that particle number fluctuations are closely related with the nuclear shell structure. As a consequence, the traditional magic number N=28 disappears in the neutron-rich area near the drip-line.
