罗马鼻：罗马鼻侧面是凸起的并且以鼻梁的额外突出为特征。

Neither is the nasal bone concave, resulting in a "dish-faced" profile; nor convex, giving the dog a Roman nose.

For compact hypersurfaces and highcodimension compact submanifolds initial data respectively, we prove that the flow hasa smooth solution for all time under almost optimal conditions. Those conditions arethat the second fundamental form on the initial submanifolds is not too large, the exter-nal force field, with its any order derivatives, is bounded, and the field is convex with itseigenvalues satisfying a pinch inequality.

由凸集分离定理及终端时间阈值函数方程，我们获得了最大值原理及最优控制时间的确定方法。

Instead of the classical Hahn-Banach separation theorem, we applythe separation results of Gerstewitzs functional to scalarizations of efficient points, so weneed not require that the feasible sets are convex sets.

由于本文是利用Gerstewitz's泛函的分离结果取代经典的Hahn-Banach分离定理，故我们不必要求可行集是凸集。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
