英文
decay coefficient-
It is found that if the cavity dissipation is losses and the reservoir is in vacuum, the quantum nonlocality appears periodically. when the cavity dissipation and the average photon number of the reservoir are taken into account, the initial quantum nonlocality will be lost. the rapidity of the loss of the initial quantum nonlocality depends on the amplitude of the initial field, the average photon number n and the cavity damping constant k
結果表明，如果腔場無損耗且處于真空庫，則量子態周期性地顯現出一定的非局域性；如果考慮到腔場的損耗和熱庫的平均光子數，那麼，量子態將會喪失它初始的非局域性，初始量子非局域性喪失的速度與初始腔場的幅度、腔的衰減系數以及熱庫的平均光子數有關，場越強、平均光子數和衰減系數越大，量子非局域性喪失得就越快。Based upon the experimental study, the stiffness and its attenuation, bearing capacity, ductility, hysteretic property, energy dissipation and failure phenomena of each shear wall with different design parameters are contrastively analyzed and the seismic mechanism of this new shear wall has been opened out
