We also derive the sufficient conditions of robust stability by rank-1 decomposition of the matrix under the assumption that uncertainty is matrix polytope structured uncertainty.

假设不确定性为矩阵多胞形结构不确定性，利用矩阵的秩-1分解，得出系统鲁棒稳定的充分条件。

By applying the filter on polytopic uncertain system, the vertex-dependent Lyapunov functions can be adopted to deliver a less conservative result.

当将其应用于具有凸多面体不确定性的网络控制系统时可以得到和系统不确定性相关联的Lyapunov函数，有效降低了设计的保守性。

On the other hand, there are no open sets in riddled basin but there are open sets in wada basin. The further study hints that this complex basin may be caused by riddling bifurcation and local-global riddling bifurcation.

通过比较发现该复杂筛形域的不确定性指数接近于零而Wada域的不确定性指数明显大于零；在该复杂筛形域中不存在开集，而Wada域中则存在着开集。

It is not so, as every player stakes a certainty to gain an uncertainty, and yet he stakes a finite certainty to gain a finite uncertainty, without transgressing against reason.

并不是说，每个赌徒为了得到不确定性而付出确定性；而是说，他要在不违反理性的情况下，为得到有限的不确定性而付出有限的确定性。

Finally the method of simulation model validation based on unascertained number analysis is presented.

文中首先指出了仿真模型确认中出现的不确定性问题，针对模型的不确定性引出了未确知有理数的相关概念及其信息处理方法。

The characteristics and unascertained qualities of existing structural information are analyzed in detail, and statistical methods of the unascertained information are established.

详细分析了在役结构的信息特点及其不确定性，提出了信息的不确定性的统计方法。

The parametric uncertainty is considered to denote the uncertainty in structure,and both parametric form and unmodeled dynamics are used to represent the influences and mechanism of uncertainty in unsteady aerodynamic forces.

将结构的不确定性考虑为参数形式，非定常气动力的不确定性考虑为参数和未建模动态两种形式，建立了不确定系统的线性分式变换模型。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
