摘要：
We have studied the problem of decoherence of two-level atoms which are put in a thermal reservoir through an external controllable driving field. The non-opposite angle element of two-level atom's reducible density rectangular array is obtained. We discuss the properties of an external driving Field when the atom's decoherence is eliminated.
