本文证明了的大小是由结构决定的。与原点无关,在这种认识的基础上,提出了用归一化结构振幅|E|估量它的三种模式。特别是通过四位相结构不变量的二级Noighborhood原理解决三位相不变量间的匹配问题而算出的,这是在没有位相数据的情况下对它的理想的估量。予期它能改进系统试差法中位相超解方程的功能,提高测得位相的准确性。 The size of this paper is determined by the structure. Regardless of the origin, on the basis of this understanding, we propose to estimate its three modes by normalized structure amplitude | E |. In particular, it is calculated by solving the problem of matching between the three phase invariants by the two-phase Noighborhood principle of invariant phase structure, which is an ideal estimation of the phase without phase data. In the meantime, it can improve the function of the phase super-resolution equation in the system trial-and-error method and improve the accuracy of the measured phase.
