查询词典 uncertain

This paper considers a absolute stability problem for a class of uncertain systems that the linear part is the convex combination of finite vertex models ,and the nonlinear part is a nonlinear sector.

本文考虑一类不确定系统的绝对稳定性问题，系统的线性部分乃顶点模型的凸组合，非线性部分是一个非线性扇区如通常绝对稳定性问题中那样。

For an uncertain system described by convex combination of interval polynomials, its Hurwitz-stability can be guaranteed by certain subset composed of vertices and edges.

对于由区间多项式的凸组合描述的不确定系统，它的Hurwitz稳定性可由某个仅由顶点和棱边构成的子集来保证，且此集合的大小与系统的维数无

As to problem of time varying delay existing in NCSs, a time-varying model including certain system and uncertain system are constructed firstly, and then stability and stabilization of these systems are discussed based on time-delay system theory, cone convex optimization theory and free weighting matrices approach. Conditions of time-dependent stability and stabilization with less conservative are given in the form of linear matrix inequalities.

针对网络时滞问题建立了时变时滞NCSs的模型(包括确定系统和不确定系统)，然后利用时滞系统理论、锥补线性化方法和自由权矩阵方法研究了NCSs的稳定性和镇定性问题，并基于LMIs形式给出具有较小保守性的时滞相关稳定和镇定条件。

This paper mainly discusses a novel non probabilistic convex set method used to estimate the eigenvalue bounds of structures with uncertain parameters.

讨论了在不确定参数的影响下估算结构特征值变化界限的一种新型非概率凸集合方法。

In this paper, interval models in the convex models are used to describe the parameters having uncertain but boundary limits such as stress and load. The shortest distance from coordinate origin to failure surface in the expand space of standardized interval variables is chosen as the non－ probabilistic reliability index.

将具有不确定且有边界限制的应力、载荷等用凸模型中的区间模型来描述，取在标准化区间变量的扩展空间中，从坐标原点到失效面的最短距离作为非概率可靠性指标。

I am a reluctant shopper (probably because of my dubious and uncertain aesthetic judgment), but, as a matter of principle, I love this country's commercial cornucopia.

我不愿购物（这可能是源于我不确定的审美判断），但从原则上来说，我喜欢这个国家在商业上的繁荣。

In addition,a negotiation-enabled solution is proposed for the verification with uncertain and incomplete model based on the counter example guided abstract refinement method.

造成不确定的因素，有可能是设计人员缺乏对系统细节的足够了解而无法给出精确的信息，也可能是系统中一些无法预计的行为造成的

When the War of Liberation had begun, a counteroffensive had not been put on the agenda , because we were uncertain of the timing.

解放战争开始时没有提出反攻的问题，那时反攻时间还捉摸不定。这件事我们要反复研究之后再把它列入议事日程。

When the War of Liberation had begun, a counteroffensive had not been put on the agenda, because we were uncertain of the timing.

解放战争开始时没有提出反攻的问题，那时反攻时间还捉摸不定。
