一段關于鋯酸鋇的英文文獻 請高手翻譯
|
|
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. |

Everything is possible
| 燒結(jié)好的鋯酸鋇陶瓷胚體制備完成并鑒定之后,這些樣品做了大量檢測,其中包括X-射線衍射,并且在樣品暴露于γ-射線前后分別做了DC-電導率和溫度的函數(shù)關系測試,一段時間(輻射衰變時間)后,樣品被移出輻射區(qū)。電導率和溫度的曲線上顯示,在60~左右突然出現(xiàn)相反的變化,可能暗示出從n型向p型轉(zhuǎn)變的半導電機制。最后,在考慮到溫度,電離輻射損傷和鋯酸鋇晶格的輻射湮滅這幾個參數(shù)的相互作用的基礎上,全部的實驗結(jié)果都進行了詳細的討論并相互關聯(lián)起來。 |
