In this paper, we calculate the k-th moments of △a1 and △a2 in mixed superposition states, discuss the higher-order squeezing in these states with Bloch vector. We also describe and calculate squeeze zones, and squeeze conditions in higher-order squeezing, discuss some optimum squeeze conditions. We conclude that two quadrature components a1 and a1 can be squeezed to higher-order at the same time under some conditions. Finally, we try to discuss the nature of squeeze in superposition states.
