双极性脉冲 meaning in English

bipolar pulse

In order to eliminate the influences caused by temperature , electrode - polarization and autoeciousness - capacitance , the traditional instrument has added complicated circuits so that it cause such shortcomings as big error , time - retardation and a relatively small scope . through the problems caused by 2 - probe electrode and ac current source , a new measuring circuit based on the excitation of bi - directional voltage pulse and the sensor of 4 - probe electrode is proposed , using single - chip to achieve auto - temperature compensation
作者在参阅国内外大量相关参考文献的基础上,从电导测试技术的原理性研究出发,分析了采用交流激励源、两电导电极为传感器的传统电导测试系统所面临的种种问题,提出并研制了一种基于双极性脉冲电压激励、以四电导电极为探头、运用单片机进行温度自动补偿的新型电导率测量系统。
