The study results showed that P ( BA-EHA)/ PVC ( BDDA, ALMA, DCPA crosslinked systems) composite particles have an obvious core-shell morphology.
研究结果表明：P（BA-EHA）/PVC（BDDA、ALMA、DCPA交联体系）复合粒子均具有较清晰的核壳结构；
With the development of Radar technic, ARPA ( Automatic Radar Plotting Aids) can display directly the course and speed of target ship and get the DCPA and the TCPA of the ship, so it is applied widely.
随着雷达技术的发展，ARPA（AutomaticRadarPlottingAids自动雷达标绘仪）由于可以直接显示目标船的航向、航速，同时可以直接得到目标船的DCPA和TCPA，因而得到了广泛的应用。
