查询词典 navigation radar

The nautical techniques of Zheng He's fleet and Columbus' fleet, including their taking a ship's bearings, celestial navigation, meteorology and knowing wind, manipulating sail and using wind, compass and it's rose, nautical chart and map, log and measuring speed, sounding channel and so on, had reached the highest level in the sail time.

郑和船队和哥伦布船队的航海术，包括测定船位术、天体导航术、气象识风术、操帆驶风术、罗盘罗经术、海图地图术、计程测速术、航道探察术等等，都达到了帆船时代迄当时为止最高的水平。由于哥伦布的远航比郑和远航晚了八十多年，故哥伦布的航海术较之郑和又前进了一步。

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。
