ionic activityの例文

• The value of the mean ionic activity coefficient " ? " ?of ions in solution can also be estimated with the Debye H點kel equation, the Davies equation or the Pitzer equations.
• Since spontaneous potential is a measure of electrochemical potential and the ionic activity of a solution is inversely proportional to its resistivity, the above equation can be simplified as SP = " E " " C " = " K " log 10 ( " R " mfe / " R " we ), where " R " mfe and " R " we are equivalent mud filtrate resistivity and equivalent formation water resistivity respectively.
