使用仪器

Maria taught them to use the sextant , an instrument measuring the height of the sun from the horizon, and then to calculate the position of a ship through the use of mathematics and celestial navigation .

玛丽亚教他们使用六分仪，这是一种测量太阳离开水平线高度的仪器，后来又教他们通过数学和天体导航法的应用来推算船只的位置。

For example, the high-power speaker subwoofer will have a strong magnetic field, has repeatedly said that even though manufacturers are Magnetically shielded, but as long as you use detection equipment to detect you will know, this Antimagnetic small water or not, and the speaker in the use of the process or the opportunity to vent some magnetic.

例如音箱中的大功率的低音炮就会产生较强的磁场，尽管厂商一再宣称是防磁设计，但是只要你拿检测仪器去检测一下就会知道，这个防磁的水份还是不小的，而且音箱在使用过程泄磁的机会还是有的。
