小比例尺海图 meaning in Chinese

small scale chart
small-scale chart

The traditional solution to the problem is to plot the forecast position of typhoon center and the ship ' s position on the < < typhoon position diagram > > , to pay much attention to the relative position between the ship and typhoon , and the tendency of their movements , to consider the affects of all kinds of factors and leave enough room , to use the plotting method of geometric relative motion to figure out the course which the ship should take to keep away from typhoon on the small scale chart
传统的解决办法是，将台风中心的预报位置和本船的船位点绘在《台风位置标示图》上，研究本船与台风的相对位置以及相互间动态的发展态势，考虑各种因素的影响并留有充分余地，在小比例尺海图上用几何相对运动标绘的方法作图绘算出本船应采取的避台航向。
