n45

From 1986 to 1990 the principal compressive stress axis had rotated toward north , to N45 ° - 60 ° E.

1986－1990年其主压应力方向向北偏转，约为N5°－60°E；

Noise traders , the fourth group , act irrationally and follow differing methods of investment either as individuals or as a group ( n45 ) .

谣言交易者（散户）是第四个族群。表现出不理性和遵循不同的投资方法。

According to the company , " each layer is made up of powerful N45 magnets that are strategically placed so the north poles face each other . This creates a repellant force , which leaves you light on your feet and happy as an astronaut . "

据该公司介绍，“每层材料里都有强力N45磁铁，嵌入的位置正好使上下两层磁铁的N极相对，产生的互斥力使人们脚步变轻，可以像宇航员一样轻松愉快地行走。”

Speaking to Live Science , mechanical engineer Patrick Jreijiri , the brains behind MoonWalker , explained that the strength of a magnet depends on its composition - a mix of neodymium , iron , and boron . So he chose N45 , which is not only the strongest but also cheaper than most magnets .

“月球漫步者”运动鞋的创意来自机械工程师帕特里克·杰吉里。在接受生命科学网采访时，他解释说磁铁的磁力由磁铁的构成决定，包括钕、铁和硼，因此他选择使用N45磁铁，既有最强磁力，也比多数磁铁便宜。
