本章的研究表明：在Born-Oppenheimer近似下，快变的量子系统的运动可以绝热地从慢变的环境的运动中分离出来；当环境的运动满足某种经典极限时，量子系统的不同绝热态分支之间量子退相干。

A detector array target of laser distant-field detect system is designed, and two key factors are analyzed. To determine the size of the array target, the laser diffract effect and the influence of atmospheric turbulence are discussed, three factors that influence the resolution of the array target are analyzed. Three factors are the dimension of laser speckle resulted by atmospheric turbulence, space sampling frequency based on sampling theory and the loss of the frequency spectrum function of the array detector.
