西北師范大學(xué)

Northwest Normal University

       西北師范大學(xué)（Northwest Normal University），位于甘肅省蘭州市，是甘肅省人民政府和教育部共建的重點大學(xué)  。入選中西部高?；A(chǔ)能力建設(shè)工程、教師培養(yǎng)計劃，為重點支持的西部地區(qū)十四所大學(xué)之一。   由北京師范大學(xué)對口支援西北師范大學(xué)。

      ZT-4A(X)型鐵電參數(shù)測試儀在本科教學(xué)中能夠起到很大的輔助作用，包括能畫出鐵電薄膜的電滯回線，定量得到鐵電薄膜材料的飽和化Ps、剩余化Pr、矯頑場Ec、漏電流等參數(shù);可以進行鐵電薄膜材料的鐵電疲勞性能、鐵電保持性能的測試，電阻測量，漏電流測量這些重要的參數(shù)指標能夠得到，能夠讓學(xué)生直觀的認識。

Northwest Normal University, located in Lanzhou City, Gansu Province, is a key university jointly built by the Gansu Provincial People's Government and the Ministry of Education. It has been selected as one of the 14 universities in the western region supported by the state in terms of basic capacity building project and outstanding teacher training program of universities in the central and western regions of China. The counterpart of Beijing Normal University supports Northwest Normal University.

ZT-4A(X) ferroelectric parameter tester can play a great assistant role in undergraduate teaching, including drawing hysteresis loop of ferroelectric thin film, quantitatively obtaining saturated polarization Ps, residual polarization Pr, coercive field Ec, leakage current and other parameters of ferroelectric thin film materials; testing ferroelectric fatigue performance, ferroelectric retention performance, resistance measurement, leakage current measurement of ferroelectric thin film materials. Some important parameters can be obtained, which can make students intuitively understand.
