The two-layer Q-ball solutions in the complex scalar field model are studied in this paper, and the Q-ball charge and energy are calculated in an analytical form. Meantime, the energy stability is analyzed, and the perturbative expression of Q-ball is obtained by means of Klein-Gordon equation. Moreover, the physical effect of Q-ball dark matter is also discussed.
