美国《国家地理杂志》发表文章解 释了地球磁场“南北颠倒”的原因。 1845年德国数学家卡尔·高斯开 始记录地球磁场数据,与那时相比,今 天的磁场强度减弱了近10％左右。而 且这种势头还将继续。电脑模拟系统 “助阵”科学家说,这种现象并不罕 见。在过去的数十亿年中,地球磁场曾 多次发生翻转,这可以在地球岩石中 找到大量证据。而他们在最近几十年 中发展的电脑模拟系统,可以很好地 演示这个翻转过程。
An article published by the National Geographic magazine in the United States explains the reason why the earth’s magnetic field is “inverted north-south.” In 1845, the German mathematician Carl Gauss began recording Earth’s magnetic field data. Compared with that time, today’s magnetic field strength has been reduced by nearly 10%. And this momentum will continue. Computer simulation system “to help out” scientists said that this phenomenon is not uncommon. In the past billions of years, the Earth’s magnetic field has been flipped many times, which can find a lot of evidence in the Earth’s rocks. The computer simulation system that they have developed in recent decades can demonstrate this flip process well.
