Based on perfect sequences and orthogonal sequence sets, a new class of mutually orthogonal sets of zero correlation zone sequences is presented.

该文基于完备序列和正交序列集，构造出一类相互正交的零相关区序列集。

Through orthogonal experiment, parameter of back zone draft multiple, roller center distance and roving twist factor are selected.

并通过正交试验对后区牵伸倍数、罗拉中心距和粗纱捻系数进行了优选。

The paper highlights the application of the orthogonal finite element method to explore the impact of variable levels and the different parameters on the thickness of the plastic zone.

采用正交有限元方法来考察不同参数、不同水平的变化对塑性带厚度的影响。
