本文提出了一种确定双谱对称结构的简单而通用的方法。双谱的主域(PD)及其正支撑域的推导方式说明了围绕PD中的三角形的争论，该三角形被Hinich和Wolinsky(1988)称为外三角(OT)，其中对于没有混叠的平稳随机抽样过程，双谱为零。回顾了非零双谱结构检验的基本统计问题。>；
The paper presents a simplifying, yet general approach to determining the symmetry structure of a bispectrum. The principal domain (PD) of the bispectrum and its region of positive support are derived in a way that illuminates the controversy surrounding the triangle in the PD, which is called the outer triangle (OT) by Hinich and Wolinsky (1988), where the bispectrum is zero for a stationary random sampled process that is not aliased. The basic statistical issues of testing for nonzero bispectral structure are reviewed. >
