你想计算湖水的电导率吗？ 你想利用电导率从而计算湖泊盐度（以获得密度）吗？ 那么这是你的工具箱！(Are you a limnologist? Do you want to compute the conductivityNZ waters of lake water (or seawater at salinities less than about 4) from its chemical composition? Do you want to compute lake salinity from conductivity (to get density?). Then THIS is the toolbox for you! Contents are:)
