论文摘要
我们表明，判别物在某些物理问题上的直接应用可能会产生微不足道的无用结果。如果模型矩阵的对称性不随模型参数的变化而变化，则判别物可能会因退化而消失。我们通过简单的$ 6 \ times6 $矩阵代表来说明这个问题。
We show that the straightforward application of the discriminant to some physical problems may yield a trivial useless result. If the symmetry of the model matrix does not change with variations of the model parameter the discriminant may vanish for all values of the parameter due to degeneracy. We illustrate this problem by means of a simple $6\times6$ matrix representation of an Hermitian Hamiltonian operator.
