This paper introduces the general methods of calculating the optimal flight trajectories of vertical navigation, including the selection of motion equations, control variables, cost functions and the optimal calculation by the variational method. 本文首先叙述垂直剖面内优化飞行轨迹的一般计算方法,从确定飞行运动方程、选择控制变量、建立成本函数到变分法优化运算。
An introduction to the ALgorithms of Optimal Trajectories for Vertical Navigation(VNAV) 垂直导航(VNAV)优化轨迹算法概述
Therefore, the application didn't loose any of it's features, but they were better grouped and incorporated on the site, by introducing a unified sidebar with a vertical tabbed navigation. 由此,我们设计了一个垂直的导航侧栏,在不丧失功能的情况下,把它们更好的排列组合。
The sample template uses a vertical bar for page navigation. 这个样例模版用一个竖线进行页面导航。
This paper makes an analysis of the difference and relationship between vertical search engine and vertical web sites, vertical search engine and meta search engine, vertical search engine and internet resources navigation, finally, two vertical search engines are introduced. 分析了垂直搜索引擎与垂直网站、垂直搜索引擎与综合搜索引擎、垂直搜索引擎与网络学科资源导航之间的区别与联系,并对国内的两种垂直搜索引擎做了介绍。
