无独有偶，ZJ-3型压电测试仪投入东华大学使用！

    这是东华大学再次购买ZJ-3型压电测试仪，而且学院还采购了ZKF-1型石英真空封管装置。相信在材料学研究上东华大学会带来一片新的天地。

Coincidentally, the ZJ-3 piezoelectric tester was put into use at Donghua University!
This is the re-purchase of the ZJ-3 piezoelectric tester by Donghua University, and the college also purchased the ZKF-1 quartz vacuum sealing device. I believe that in the study of materials science, Donghua University will bring a new world.
