【Abstract】 The coherence of trapped ion being put in a thermal radiation model standing wave field through an external controllable driving field is investigated. The time evolution properties of non-opposite angle element of trapped ion’s reducible density rectangular array is discussed. Coherence properties of trapped ion is studied when the trapped ion interacts with an driving field in the thermal radiation model standing wave field. We obtain the properties of an external driving field when trapped ion’s coherence is maintained.更多还原
