asymptotic value meaning in Chinese

渐近植
渐近值, 近似值

It is found that in the absence of dissipation and average photon number of the reservoir the linear entropies of the atom and the field varies with time periodically , going to zero at the disentanglement times , and the period is the same as that of bell function and the linear entropy of the total system is zero at any time . if the cavity dissipation and the average photon number of the reservoir is taken into account , the linear entropies of the atom and the field present local maxima and minima and the difference between them diminishes with time , tending to asymptotic values
结果表明，在忽略腔损耗和热库的平均光子数时，原子和场的线性熵有周期性的变化，在没有纠缠的时刻，值为0 ，此时的周期与bell函数相同，而系统的线性熵在任何时刻都为0 ；如果考虑到腔场的损耗和热库的平均光子数，原子和场的线性熵有局部的最大值和最小值，它们之间的差距随时间逐渐减小，趋向一个渐进值。
