摘　　要：依据宏观现象与量子物理现象之间的相类似之处,利用干涉原理解释了和频场强度随着传输距离发生类似于原子系统中的Rabi振荡的物理机理,从Landau-Zener遂穿(LZT)的角度揭示了光学参量转换过程中的能量转移机理,以渐进解、解析解的形式详细展示出和频产生过程中的能量转移过程.to an analogy of the macroscopic phenomena to quantum physics, the physical mechanism that the sum frequency field intensity oscillate with the transmission distance, which is similar Rabi oscillation of the atom transition process in the two-level system, is explained with the interference theory. The energy transfer mechanism of the optics parametric conversion process is revealed from the points of Landau-Zener tunneling （LZT）, and the producing process of sum frequency signal is showed detailedly with asymptotic, analytical solution.
