我们研究了在双谐振场驱动下，量子粒子在Tietz-hua量子势中的响应：低频力和超高频力。响应的特征是在外加电场的影响下，一阶跃迁几率振幅|S|^{2}出现极大值。结果表明，在外场没有高频分量的情况下，|S|^{2}呈现出明显的共振序列，而高频场振幅的增大则导致|S|^{2}的极小值。然而，|S|^{2}极大值出现在低频区域，在单谐振力存在的情况下，它可以被认为是很弱的。
We investigate the response of a quantum particle in the Tietz-Hua quantum potential driven by biharmonic fields: a low-frequency force and a very high frequency force. The response is characterized by the occurrence of a maximum in the first-order transition probability amplitude |s|^{2} under the influence of the applied fields. It is shown that in the absence of the high-frequency component of the applied fields, |s|^{2} shows a distinct sequence of resonances, whereas an increase in the amplitude of the high-frequency field induces minima in |s|^{2}. However, the |s|^{2} maximum occurs in the low-frequency regime where it may be considered otherwise weak in the presence of a single harmonic force.
