1) weakly periodic ring
弱周期环
2) weakly graded periodic ring
弱分次周期环
3) weak coupling cyclic periodic structure
弱耦合循环周期结构
1.
Satellite structure is typical weak coupling cyclic periodic structure.
星载天线普遍属于弱耦合循环周期结构,其动力学特性非常复杂,且随着口径的增大,天线结构的振动特性及振动主动控制的研究就更加成为一个难题。
4) weakly almost periodic
弱概周期
1.
In this paper, weakly almost periodic of C-semigroup is studied, Let ()uis almost-orbit of a bounded C-semigroup on a Banach space X, assuming that ()u has weakly relatively compact range in X, We obtain that ()Cu is weakly almost periodic.
假设在有界C-半群的概轨道()u的轨迹在Banach空间X中是弱紧的条件下,研究了C-半群的弱概周期性,得到了()Cu是弱概周期的;特别在X是自反的Banach空间的情况下,不用其假设条件也能获得同样的结论;相应获得了有界C-半群点的弱概周期。
6) weak aperiodicity
弱非周期性
补充资料:弱弱联合
弱弱联合是指两个总体实力都不强但都拥有自己独特的某方面优势的企业之间进行联合,以形成较强的实力。弱弱联合,弱企业之间优势互补,可以形成整体实力变强的效应。
