摘要
我们表明，非相对论历法理论中两种时间平移的相对论类比是存在两个不同的 Poincaré 群。`内部' Poincaré 群类似于标准正规量化方案中产生的群；`外部' Poincaré 群类似于标准理论的拉格朗日描述中产生的群。特别是，它对标准正规场论中隐含假设的时空层析进行显式变换。

备注
32 pages, Latex. In a non-relativistic history theory there exist two distinct Poincare' groups. The `internal' Poincare' group is analogous to the one that arises in standard canonical quantisation scheme; the `external' Poincare' group performs explicit changes of the spacetime foliation that is implicitly assumed in standard canonical field theory
