中文摘要：

当一个单独的分子被镶嵌在一个主体的媒质中时，外加的激光场可以使其中的隧道效应被抑制。外场作用时，形成A型三能级系统，通过缀饰分析法、黑态明态分析法和一些近似，得出结论。明黑态的分析乃是对这一特殊系统发生相干隧穿抑制现象的一种物理解释。在一定的情况下粒子不但可以被定域在各自所处的阱里，而且可以完全定域在较低的势阱里。

英文摘要：

The suppression of Quantum Dynamical tunneling is predicted to occur when a laser field drives a transition in an isolated, single molecule embedded in a host medium. A externalforce having quasiresont frequency drives trasitions between the ground and excited states, which forms a A-type systerm. ThrOugh dressed state analysis, dark and bright representation analysis and some approximation, the solution is gained. Dark and bright representation analysis is a physical interpretation; in some condition, particles can be completely localized in one well or be localized in lower doublet.
