| 英文摘要 | The explicit solution for the time evolution of the Nth rank spatial moment ∫□rj¹rj²…rjNd³χ (rj is the jth cartesian component of the position vector r→) of some field □( r→ , t )has been obtained. □ can be any spatially bounded massive field satisfying a relativistic first order linear ("Dirac-like") differential equation, such as the Dirac bi-spinor. The solution for the Nth moment is a "polynomial" in time of degree N, whose coefficients are oscillatory functions with only the frequency ω=me ²/ ћ being present. The spin of the field □ does not affect the form of the solution. |
