对于无自旋的一维费米子系统，两体相互作用的非零短程极限导致波函数不连续。我们证明了这个费米子系统和玻色子粒子系统的等价性与两体$\ensuremath{\delta}$-函数相互作用的强弱耦合的逆转的作用。
For a system of spinless one-dimensional fermions, the nonvanishing short-range limit of a two-body interaction is shown to induce the wave-function discontinuity. We prove the equivalence of this fermionic system and the bosonic particle system with a two-body $\ensuremath{\delta}$-function interaction with the reversed role of strong and weak couplings.
