Dixon method was adopted to construct a 22×22 Dixon matrix and then the greatest common divisor of two columns was extracted. After expanding the determinant of the matrix, a 64 degree univariate polynomial equation was obtained and 6 extraneous roots were canceled in the process of solving the other 3 variables.

结合矢量法和复数法建立了4个几何约束方程式，使用Dixon结式构造22×22的Dixon矩阵，对两列提取公因式后展开矩阵的行列式得到一元64次多项式方程，回代过程中去掉6组增根后得到58组解。

Firstly, four geometric loop equations are set up by using vector method in complex number fields. Secondly, three constraint equations are used to construct the Dixon resultants, which is a 6×6 matrix and contain two variables to be eliminated. Extract the greatest common divisor of two rows and two columns of Dixon matrix and compute its determinant to obtain a new equation. This equation together with the forth constraint equation can be used to construct a Sylvester resultant.

首先使用矢量法和复数法建立4个几何约束方程式；再使用Dixon结式法对3个方程式构造一个含有2个变元的6×6 Dixon矩阵，提取其中2行列元素的公因式，将新矩阵的行列式展开后得到二元高次多项式方程，该方程与剩下一个方程使用Sylvester结式消去一变元，得到一元高次方程。

The basic steps of this method are as follows.The firststep is to derive a necessary condition such that the families of quasipolynomials withone parameter,corresponding to the edges of the polytope,have pure imaginary rootsby using the Dixon's resultant for polynomials.Then to check that the casescorresponding to the parameters obtained in the first step are in fact impossible byusing the generalized Sturm criterion and some stability criteria.

其基本思路是先利用多项式方程组的Dixon结式理论导出使各棱边对应的单参数特征拟多项式有纯虚根时，参数值应满足的一个等式条件，即所谓的Dixon结式等于零，然后由广义Sturm判别法验证对所有参数值，Dixon结式不等于零，或使结式等于零的解不产生特征拟多项式的纯虚根。

Although vitamin D deficiency is believed to be more common in northern states where sunlight is less pronounced and the elderly spend less time out of doors, Dr. Felson advised that it should not be ignored in lower latitudes."We're talking about everybody 60 and over in the United States above the Mason-Dixon line and maybe even below the Mason-Dixon line. The prevalence of vitamin D deficiency is extremely high," he told Medscape in an interview.

维生素D被认为在北部的几个州会比较普遍，因为阳光比较少，而老年人也比较不常在户外；但是，Felson医师建议，低纬度的地区也不应该被忽略；Felson医师在接受Medscape访问时指出，我们所谈的是在美国境内，梅生迪克生(Mason-Dixon)分隔线以上地区内所有60岁以上的人，也可能包含了梅生迪克生(Mason-Dixon)分隔线以下的地区，维生素D缺乏症是很流行的。
