The temperature dependences on the resistance in all the thin films show that in the low temperature range the width of eg band level changes the transports , but in the high temperature range the thin films forms the small polarons hopping conductivity . the phase transition induced by the current is explained by the demagnetization and lattice distortion
在高溫部分，材料呈現(xiàn)小極化子跳躍形式輸運特征；實驗研究了不同偏置電流對薄膜的相變影響，表明電場可以引起材料中磁性的變化和晶格畸變，導致相變溫度點向低溫方向移動；材料的光致相變研究表明光子能量、光強和極化方向?qū)斶\性質(zhì)有影響。
To characterize the particle size of the srce03 products , some methods used to determine the crystalline grain size and crystal lattice distortion rate of nanostructured powder based on xrd data were studied . it was found that some methods had their shortage . to rationalize the calculation , a proper treating method was recommended
為了表征所制備的納米srceo3粉體的粒度，本論文對利用粉晶x射線衍射技術表征納米粒于的粒度和晶格畸變的方法進行了研究，發(fā)現(xiàn)已有的某些方法中存在的不合理性，針對表征方法的合理化提出了自己的見解。
