英语词汇“chemical potential”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

chemical potential n. (a) a thermodynamic function representing the change in the Gibbs free energy of a component of a system which would result from the addition of an infinitesimal quantity of that component, all other conditions remaining unchanged (see potential n. 5b); usually denoted by the symbol μ; (b) an analogous function variously defined for electrons and other particles.For each of the components present in a particular phase of a thermodynamic system, the chemical potential is equal to the partial derivative of the Gibbs free energy of the phase with respect to the quantity of the component present in the phase (with temperature, pressure, and the quantities of all other components remaining constant). Chemical potential can also be defined in terms of internal energy, enthalpy, or Helmholtz free energy.Used in a somewhat different sense in quot. 1884.
