用程序升温脱附研究Nd_（1－x）Sr_xMnO_3体系氧的吸附、脱附特性

TPD Study on Oxygen Sorption-Desorption Properties of Nd_(1-x)Sr_xMnO_3

用氧的程序升温脱附（ＴＰＤ）技术测试了钙钛矿型复合氧化物Ｎｄ（１－ｘ）ＳｒｘＭｎＯ３（ｘ＝０．０，０．２，０．４，０．６，０．８，１．０）系列试样体相内的缺陷结构．发现随着Ｘ的变化，脱附氧量呈现出不同的变化规律。对此，用晶体化学和固体化学的基本理论进行了解释。

From tests of defect structure of perovskite-type mixed oxides using TPD technology,it is found that the amount of desorption oxygen follows different rules with the change of the x. This is explained by using the basic theory of crystal chemistry and solid chemistry.
