%X This paper explores the potential of combating the decoherence by associating quantum generalized measurement with decoherence-free subspaces(DFS).It is demonstrated that associating quantum generalized subspace projector measurement (QGSPM)and quantum generalized case-projector measurement(QGCPM)with the operator conditions for DFS will enhance the capability of suppressing the decoherence for both Markovian and non-Markovian open quantum systems.It is emphasized that quantum measurement can be regarded as a means to manipulate quantum states.This method is advantageous because the coherent control Hamilton can be constructively designed.
