"Which Way" experiments,possible breaking of wave-particle duality and new duality

Recent some experiments showed many new characters in quantum physics.The Which Way(WW) experiments imply possible breaking of wave-particle duality.From this the effectiveness of quantum-wave should be tested continuously for single particle,an exceedingly small time-space,strong and weak interactions of short-rang,and high energy,etc.These experiments provided some possibilities on developing direction of particle physics.According to the discussion of the statistical foundation of quantum mechanics and total characters of particle physics,it is derived a possible direction of theoretical development: new duality of symmetry and statistics.Since a relation between statistics and quantum field is me-to-one,the new duality corresponds to the general extensive quantum theory.
