压敏效应 meaning in English

voltage-sensitive effect

Strain gauges work in accordance with the principle of piezoresistive effect : elongation increases , compression reduces the electrical resistance
应变测量元件根据压敏效应原理工作：当拉伸增加时，压缩力会使电阻减小。
The result shows are as following , first , using a . c . impedance measurement to measure the compression sensibility of cfrc can eliminate the polarization effect at the electrode of cfrc specimen and the thermoelectric force of the electrode effectively ; the thermo sensitive effect can be avoided by using little electric current , so the a . c
结果表明：采用交流阻抗法测试cfrc试块的压敏效应可以有效地消除cfrc试块的电极处的极化效应和电极界面的热电动势；采用小电流供电可避免温敏效应，因此交流阻抗法要比直流电阻法稳定性好。
