spectral multiplicity

It is studied the effect of overlapped degree of spectra on the accuracy through the simulated experiment data.

通过模拟实验,对待测物各型体间的波谱重叠程度及待测物与干扰物的分布分数曲线之间的波谱重叠程度对测定准确度的影响进行了研究。

In this paper, the basic principle of the bispectrum is discussed.

阐述重谱（Ｂｉｓｐｅｃｔｒｕｍ）的基本含义和基本原理，介绍重谱估计的常用方法、算法原理及其硬件实现：说明重谱估计的特点及实际应用；指出重谱估计的发展方向。

According to the properties that an object bispectrum corrsponds to the image of the object in speckle masking method, the object bispectrum is adopted as the standard function to test the iterative results.

根据斑点掩模法中目标重谱与目标像间的相互对应的性质 ,用目标重谱作为检验迭代结果的标准函数。

 can avoid the complex phase retrieving process when phase spectrum was recovered from the bispctrum of an observated object image, and so the phase error transmission and accumlation were removed too.

在天文斑点成像技术中 ,Hofmann等提出的迭代最小二乘法———积木法 ,能避免在由被观测目标像的重谱复原相位谱时复杂的相位递推过程 ,因而相位误差的传递和积累也被消除了。

Some actual problems that will be faced when to recover object phase spectrum from the bispctrum with a micro computer are discussed, including the huge information of the bispectrum contradict the limited storage .

讨论了在微机上实现由重谱复原目标相位谱时所面临的实际问题：巨大的重谱信息量和计算机有限存储空间的矛盾；递推相位区域和路径；相位缠绕和误差积累等。

The heavy baryon spectra were studied in the framework of quark model.

在夸克模型的框架下研究了重重子谱,通过高斯展开方法解薛定谔方程求得重重子的夸克模型研究。
