本文给出了八顶点模型在临界温度以下的自发极化率P0的函数形式，并考虑了三种特殊情况，给出了其精确表达式。结果与低温级数展开式的四阶近似一致。这意味着临界指数β e随pi /$Gm线性变化，与先前获得的其他指数一样。
A functional form of the spontaneous polarization P0 of the eight-vertex model below the critical temperature is conjectured, and an exact expression then determined by considering three special cases. The result agrees to fourth order with the low-temperature series expansion. It implies that the critical exponent beta e varies linearly with pi /$Gm, as do the other exponents previously obtained.
