论文摘要
在本文中，我们为所有特征值建立了必要和充分的条件，除了关于Hill方程的最低，周期性和反周期性问题，就复杂价值的潜在$ Q（x）$而言。
In this paper, we establish necessary and sufficient conditions for the doubleness all of the eigenvalues, except the lowest, periodic and anti-periodic problems for Hill's equation in terms of the complex-valued potential $q(x)$.
