It will occupy a lot of time to overlay ship trajectories,especially long ship motion trajectory,so as to decrease the display speed of system on electronic chart significantly.

The possible origins and immigrant pathways of the white-backed planthopper (WPH) Sogatella furcifera (Horvth) in the middle reaches of the Yangtze River were investigated with trajectory analysis.

The possible sources and immigrant pathways of the brown planthopper (BPH),Nilaparvata lugens(St*[l), in the middle reaches of the Yangtze River were investigated by the means of trajectory analysis.

The meteorological data on the mid-and small-size population source regions (such as Nanning and Shaoguan) which were determined or found out by trajectory analysis were used to predict the peek date of immigration and the adult number about one or two months ahaed of the practical occurrence in seven representative counties in Huaihe and Changjiang rice areas.

This paper proposes an algorithm for the sensitivity of stable index to assesse the generator active power output based on trajectory analysis method and trajectory sensitivity.
