液态和超临界水的电导率高温和高压的方程，结合了一些早期观察到的趋势和新发现的还原态关系在这里提出。据信，用该方程计算的温度从0到374/sup 0/C，压力从饱和蒸汽压到1000 MPa（10 kbar）时，液态水的电导率在± 1到± 5%范围内。对于流体密度约为0.3 ~ 1g cm/sup-3/，温度为374 ~ 1000/sup 0/C的超临界水，在最高温度和压力下，不确定度可能从5%增加到15%。
The electrical conductance of liquid and supercritical water to high temperatures and pressures is represented by an equation that incorporates some earlier observed trends and a newly discovered reduced-state relationship presented here. Calculations with the equation are believed to describe within +-1 to +-5% the specific conductance of liquid water at temperatures from 0 to 374/sup 0/C and at pressures from saturated vapor pressure to 1000 MPa (10 kbar). For supercritical water at fluid densities from about 0.3 to 1 g cm/sup -3/ and at temperatures from 374 to 1000/sup 0/C, the uncertainties probably will increase from 5% to perhaps 15% at the highest temperatures and pressures.
