| 单词 | Dirac equation |
| 释义 | Dirac equation An equation derived by P. A. M. Dirac, which can be regarded as an interpretation of the Schrödinger equation that takes account of relativity. It can be written in the form: iα∇;ψ + (mc/ℏ) ßψ = (i/c)δt . where m is the mass of a free particle, c the speed of light, t the time, ℏ is the Dirac constant. The wave function is ψ and α and ß are square matrices; i is v-1. The Dirac equation, unlike the Klein-Gordon equation, can be used with spin–½ particles, such as the electron; indeed, it predicts that all fermions must have spin–½ it also predicts the existence of antiparticles |
