[求助] 一段关于锆酸钡的英文文献请高手翻译

Well-sintered barium zirconate ceramic bodies have been prepared and identified. Extensive measurements have been made on these specimens, including X-ray diffraction, and DC- electrical conductivity as a function of temperature before and after exposure to a gamma- radiation dose and after various periods (radiation decay time) following removal of the specimens, from the radiation field. The resistivity vs. temperature curve showed an abrupt change at around 60 ~ in the reverse direction, indicative of a probable transition from an n- to a
p-type semiconduction mechanism. Finally, all the results are discussed in detail and correlated on the basis of the interactions of temperature, ionizing radiation damage and radiation annihilation with the barium zirconate lattice.

烧结好的锆酸钡陶瓷胚体制备完成并鉴定之后，这些样品做了大量检测，其中包括X-射线衍射，并且在样品暴露于γ-射线前后分别做了DC-电导率和温度的函数关系测试，一段时间（辐射衰变时间）后，样品被移出辐射区。电导率和温度的曲线上显示，在60~左右突然出现相反的变化，可能暗示出从n型向p型转变的半导电机制。最后，在考虑到温度，电离辐射损伤和锆酸钡晶格的辐射湮灭这几个参数的相互作用的基础上，全部的实验结果都进行了详细的讨论并相互关联起来。
