针对约束矩阵具有与其所对应的零陷个数相同数量的大特征值的性质，应用盖氏圆盘定理比较精确地估计一个零陷情况下约束矩阵特征值的界。

The character of the eigenvalues of the constraint matrix was aimed, and the character is that the matrix has the same number of larger eigenvalues as number of the nulls that the matrix denoted.

用同伦方法分析了可分解映射的零点存在性，并获得它对一类非线性特征值问题的应用。

Using homotopy methods, this paper gives an analysis on the existence of zeros of the decomposable mapping, and finds its application to a class of nonlinear eigenvalue problems.

因此，所有的特征值为零或正。

Hence, all eigenvalues are zero or positive.
