21. :Electrode potentials measure the equilibrium point of the chemical reaction that takes place at the electrode. 22. An equilibrium point is " hyperbolic " if none of the eigenvalues have zero real part. 23. There is an equilibrium point where the two fields cancel, but it is an unstable equilibrium. 24. The market, supply and demand factors will drive the price of an asset at equilibrium point . 25. Its derivative with respect to the reaction coordinate of the system vanishes at the equilibrium point . 26. If one or both of these opposing influences are non-linear, equilibrium point ( s ) result. 27. Since vibration means mechanical oscillations about an equilibrium point , the string would vibrate back and forth. 28. So a policy measure might just worsen the condition by taking, the economy, past the equilibrium point . 29. They slowly librate around their respective equilibrium points , periodically moving closer to Jupiter or farther from it. 30. Thus, the conceptual and technical complications regrding the existence of Nash equilibrium point are not pertinent here.
