quasi-orthogonal meaning in English

准正交的
准正交线

Then based on the analysis of the constructions of wh , go and ls sequences , the corresponding correlation properties are derived and methods of selecting subsets with good periodic mean - square cross - correlation property or aperiodic mean - square correlation property from the wh set and go sequence set whose go zone z = l are investigated . furthermore , the methods of truncating the go sequences to obtain the quasi - orthogonal ( qo ) set whose family size m is larger than the length l and the quasi - generalized - orthogonal ( qgo ) set whose size m is larger than li2z are discussed , together with the numerical results of the correlation properties
基于这些结果，探讨了如何从wh序列集和广义正交区z = 1的go序列集中，分别按照周期互相关均方特性最优和非周期相关均方特性最优的准则选择性能较好的序列子集；同时讨论了将广义正交序列截短来获得准正交( qo )序列集和广义准正交序列集( gqo )的方法，并给出了这一类序列相关特性的数值计算结果。
