rhumb lines and map wars: a social history of the mercator projection

等方位线与地图战：墨卡托投影的社会史

For quasi-real-time method, the real-values of COG and SOG are calculated by Mid-Latitude, Mercator or Bowring sailing method, the geographic coordinates obtained from DGPS are taken as the original datum of the three sailing method s.

在准实时法中，利用差分卫星定位仪给出的地理坐标，根据中分纬度法、墨卡托法或波林法算得航迹向与对地速度的真值。

But deals over the past two years-which last year hit a record 20 billion euros, or$ 22.4 billion, according to a survey by Rhodium Group and the Mercator Institute-have begun targeting leading-edge companies with crucial technologies and iconic brand names.

但过去两年里的交易开始把目标对准拥有关键技术和标志性品牌的前沿企业。荣鼎集团（Rhodium Group）和墨卡托中心共同进行的一项调查显示，去年这类交易达到了创纪录的200亿欧元。
