After the numerical calculation, the schematic phase diagram is discussed with an emphasis on the role of impurity. When n10 = n20, the phase boundaries coincide with each other; when n10 【 n20 and U12 【 0, the phase boundaries do not intersect at all; when n10 【 n20 and U12 】 0, the phase boundaries may or may not intersect, depending on the values of U12, n10 and n20.展开更多
