Since the number of generalized coordinates is large when using the finite elemen

因为用有限元离散时，柔性薄板的广义坐标规模较大，故仿真计算需要时间较长，所以模态截断法被用来缩减广义坐标数量，提高计算效率。

Since the number of generalized coordinates is large when using the finite element method, MTA is usually used for improving computational efficiency and only lower-order modes are chosen.

因为用有限元离散时，柔性薄板的广义坐标规模较大，故仿真计算需要时间较长，所以模态截断法被用来缩减广义坐标数量，提高计算效率。

Now that we can not change the coordinates of time,occasionally moving about the space coordinates so is a point breathe new life into it?

既然我们无法改变时间的坐标，偶尔移动一下空间的坐标何尝不会得到一个新的生命点呢？

This method has more practical value. First, this article has introduced the research situation of real-time transportation information collection, including the taxi electronic dispatch system as well as the corresponding technology. Analyzed the mothod of map coordinates transformation and the match method of vehicles localization data, then has analyzed the vehicles localization effective sampling with emphasis according to the drivers driving custom to get the tavel time of the road sections. It has filled the transportation blank region data.With the experiments of real data, explained this algorithm could obtain the road section reasonable travel time, int could describe the road network real-time condition.
