查询词典 weakly bounded set

The reference domain is assumed to be a bounded open set of R~N with boundary Γ of class C~2. We investigate in this paper the null controllability for the semilinear parabolic equations in non-cylindrical domains. The fixed point method is used in the proof.

本文讨论了定义在上述非柱形区域中的半线性抛物方程零能控性，我们使用的方法主要是通过同胚映射将非柱形区域中的抛物方程转化为柱形区域中的抛物方程，再利用不动点方法得到半线性抛物方程的有关结果。

Considering the uncertainties of peak acceleration and frequency characteristics by using a bounded convex set model,the bounds of shear forces are derived from the Chinese seismic code,and then a new lateral bound load method for pushover analysis is proposed.

动力弹塑性时程分析法是一种较理想的结构抗震性能评估方法，但由于地震动的选取对其结果影响较为显著，而且目前尚无关于地震动选取的统一标准，从而严重地阻碍了动力弹塑性时程分析法的应用。

This indicates that it is impossible to design a Clarke-Gawthroptype self-tuning controller or an adaptive pole placement controller for unknown nonminimumphase plants to track arbitrary bounded set point sequences asymptotically.

这表明对未知离散非最小相位系统，不可能设计Clarke－Gawthrop型自校正控制器或自适应极点配置控制器去渐近跟踪任意有界设定序列。

2，研究了在完备度量空间中一对模糊映象满足一些特定不等式条件，以及当其截集是中非空有界闭集时，该对模糊映象的公共不动点的存在性问题。

Different from the case of strict minimal siphons in a net system, the number of elementary ones is bounded by the smaller of place count and transition count. Based on the ideas mentioned above, this thesis proves that the set of elementary siphons is not unique, while different ones may lead to different control results.

本文在此研究的基础上，论证了网系统中的基本信标的不唯一性，控制不同的基本信标可以得到不同的控制效果，进而提出了最优基本信标的概念并给出了相应的计算方法，应用这一计算方法可以在多项式时间内求得一组最优基本信标，也就是说，控制该组基本信标相对于其他的基本信标可以使得系统Petri网模型具有最多的可达状态，这在实际中，意味着系统具有更大的灵活性。
