| 单词 | transport coefficients |
| 释义 | transport coefficients Quantities that characterize transport in a system. Examples of transport coefficients include electrical and thermal conductivity. One of the main purposes of nonequilibrium statistical mechanics is to calculate such coefficients from first principles. It is difficult to calculate transport coefficients exactly for noninteracting systems and it is therefore necessary to use approximation techniques and/or model systems. A transport coefficient gives a measure for flow in a system. An inverse transport coefficient gives a measure of resistance to flow in a system. An example of an inverse transport coefficient is resistivity |
