Samples of Sm0.5Sr0.5CoO3–δ were annealed in different atmospheres（Ar,N2,and O2） and temperatures（400 1200 oC）,and changes in their masses,structures,surface transport properties,optical properties,and oxygen nonstoichiometries were investigated using thermogravimetric（TG） analyses,X-ray diffraction...
