[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.
