查询词典 eclipsing binary

And another construction methods for perfect and quasi-perfect binary array pairs are presented with the help of the relationships among the perfect, quasi-perfect and double quasi-perfect binary array pairs. On the other hand, a new kind of discrete signal is presented in this paper, which is the punctured binary sequence pair and the punctured binary array pair.

另一方面，本文提出了一种新的离散信号，即屏蔽二进序列偶和阵列偶，建立了完整的屏蔽二进序列偶和阵列偶的理论体系，它包括最佳屏蔽二进序列偶理论、最佳屏蔽二进阵列偶理论、准最佳和双准最佳屏蔽二进阵列偶理论，以及屏蔽二元互补序列偶理论。

With the help of these conditions, computer efficiently searches out many quasi-perfect and double quasi-perfect punctured binary array pairs. The relationships among perfect punctured binary array pair, quasi-perfect and double quasi-perfect punctured binary array pair is presented. Specially, when first and second dimension period of the punctured binary ar

定义了非周期屏蔽二元序列偶的自相关函数、屏蔽二元互补序列偶和最佳屏蔽二元互补序列偶，给出并证明了屏蔽二元互补序列偶的变换性质；和它存在的组合允许条件，用计算机搜索出若干最佳屏蔽二元互补序列偶；给出了屏蔽二元互补序列构造出新的屏蔽二元互补序列偶的四种构造方法；并且，给出了利用不同长度的二元互补序列和屏蔽二元互补序列偶构造出新的屏蔽二元互补序列偶的四种构造方法。
