西北师范大学

Northwest Normal University

       西北师范大学（Northwest Normal University），位于甘肃省兰州市，是甘肃省人民政府和教育部共建的重点大学  。入选国家中西部高校基础能力建设工程、卓越教师培养计划，为国家重点支持的西部地区十四所大学之一。   由北京师范大学对口支援西北师范大学。

      ZT-4A(X)型铁电参数测试仪在本科教学中能够起到很大的辅助作用，包括能画出铁电薄膜的电滞回线，定量得到铁电薄膜材料的饱和极化Ps、剩余极化Pr、矫顽场Ec、漏电流等参数;可以进行铁电薄膜材料的铁电疲劳性能、铁电保持性能的测试，电阻测量，漏电流测量这些重要的参数指标能够得到，能够让学生直观的认识。

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.
