河南邦信阴极(ji)(ji)(ji)(ji)(ji)保护参(can)比电(dian)(dian)(dian)(dian)(dian)极(ji)(ji)(ji)(ji)(ji)是(shi)测(ce)量各(ge)种电(dian)(dian)(dian)(dian)(dian)极(ji)(ji)(ji)(ji)(ji)电(dian)(dian)(dian)(dian)(dian)势(shi)时作(zuo)为参(can)照比较的电(dian)(dian)(dian)(dian)(dian)极(ji)(ji)(ji)(ji)(ji)。将被测(ce)定(ding)的电(dian)(dian)(dian)(dian)(dian)极(ji)(ji)(ji)(ji)(ji)与已知(zhi)电(dian)(dian)(dian)(dian)(dian)极(ji)(ji)(ji)(ji)(ji)电(dian)(dian)(dian)(dian)(dian)势(shi)数(shu)(shu)值的参(can)比电(dian)(dian)(dian)(dian)(dian)极(ji)(ji)(ji)(ji)(ji)构成电(dian)(dian)(dian)(dian)(dian)池，测(ce)定(ding)电(dian)(dian)(dian)(dian)(dian)池电(dian)(dian)(dian)(dian)(dian)动势(shi)数(shu)(shu)值，就可计算(suan)出(chu)被测(ce)定(ding)电(dian)(dian)(dian)(dian)(dian)极(ji)(ji)(ji)(ji)(ji)的电(dian)(dian)(dian)(dian)(dian)极(ji)(ji)(ji)(ji)(ji)电(dian)(dian)(dian)(dian)(dian)势(shi)。参(can)比电(dian)(dian)(dian)(dian)(dian)极(ji)(ji)(ji)(ji)(ji)是(shi)电(dian)(dian)(dian)(dian)(dian)极(ji)(ji)(ji)(ji)(ji)反应(ying)为单一的可逆反应(ying)，电(dian)(dian)(dian)(dian)(dian)极(ji)(ji)(ji)(ji)(ji)电(dian)(dian)(dian)(dian)(dian)势(shi)稳定(ding)和重现性好。通常多用微溶盐(yan)电(dian)(dian)(dian)(dian)(dian)极(ji)(ji)(ji)(ji)(ji)作(zuo)为参(can)比电(dian)(dian)(dian)(dian)(dian)极(ji)(ji)(ji)(ji)(ji)，氢电(dian)(dian)(dian)(dian)(dian)极(ji)(ji)(ji)(ji)(ji)只(zhi)是(shi)一个(ge)理想(xiang)的但不易于实现的参(can)比电(dian)(dian)(dian)(dian)(dian)极(ji)(ji)(ji)(ji)(ji)。
