相位分布 meaning in English
phase distribution
Examples
- For designing a transmission computer optical element , it gives a method to improve the traditional gs ( gerchberg - saxton ) algorithm by the method of calculate phase while designing reflecting element , and gains initial data
对在透射式元件的设计过程中,提出利用设计反射式元件时计算相位分布的方法对传统gs算法进行改进,计算出gs算法的迭代初始值,从而有效地改进了gs算法的不足。 - The serpentine feed is the core of a frequency scanning antenna feed system , which produce proper amplitude and phase distribution for the antenna arrays . most of all , it make the beam scanning over a large angle range by means of changing operating frequency
它为天线阵提供要求的幅度、相位分布，更为重要的是当频率发生少许变化时使线源的等相位面产生显著的倾斜，完成波束在空间扫描。 - The test results show that different patterns of pd correspond to different demodulating signal waveforms , the pd phase angle in ac , and spectrum characteristics . therefore the pd patterns can be recognized by the uhf characters of different pd signals in gis
试验结果表明，不同缺陷类型的局部放电在其检波信号波形、局部放电工频相位分布和超高频频谱特征是有所不同的，可以依据这些特征对gis内的局部放电类型进行识别。 - The results of simulated and xperimental fringe patterns are presented to illustrate the processing of the new method . secondly , considering the phase of fringe pattern can be recovered by solution of a equence of linear systems of equations , and the corresponding matrices are quite large and parse , the optimum numerical methods are available to solve this kind of systems
结果表明，用本文的方法，能够有效滤除掉条纹图中的高斯型、均匀分布的随机型噪声，从而由单幅条纹图获得对应于该条纹图的全场相位分布，文中给出了模拟和实验的处理结果。 - This method assumes that each inteferogram has an identical phase shift that can be found out by least - suqares fitting . this algorithm determines any errors of phase shifts deviating from their i ntended values and also suppresses the errors by substituting actual values in subsequent computation . the algorithm can solve the problem of random phase - shifting very accurately , but the algorithm needs a great of iteration number and considerable calculation
In - bokkong等人从同一干涉图中诸象素相移量相等这一认识出发，提出求解各干涉图的相移量的方法， in - bokkong的算法是通过交替求解相位分布和相移量来进行的一种迭代算法，这种方法可以解决随机相移误差问题，且有很高的精度，但迭代次数较多，计算量较大。
