科学家发现,地球磁场正趋于不断减弱,磁场变化将影响地球生物和自然界。 根据德国波茨坦地球物理所科学家的研究,地球自诞生以来,地球磁场强度一直在发生细微变化,但是近300年来,磁场强度减弱了约10％,这种减弱趋势似乎还在加速,尤其南大西洋的磁场强度衰减表现得更为明显,20年里减弱了10％,近地卫星被宇宙高能粒子击穿的事故90％发生在南大西洋上空。 据科学家研究,6000年前地球磁场曾经减弱到现今的水平,后来逐渐恢复,3000年前又出现过一次磁场衰减过程。地球磁场的衰减要持续多久?地球磁场是否会衰竭?对人类和自然界有多大影响?科学家目前还无法对这些疑问作出圆满解释。为此,“德意志研究联合会”实施一项新课题,研究导致地球
Scientists have discovered that the Earth's magnetic field is tending to weaken, and changes in the magnetic field will affect the Earth's biology and nature. According to scientists from the Potsdam Geophysical Institute in Germany, since the birth of the Earth, the strength of the Earth's magnetic field has been changing slightly. However, the intensity of the magnetic field has been reduced by about 10% in the past 300 years. This downward trend seems to be accelerating, especially in the South Atlantic The decay of magnetic field intensity is more obvious, which has been reduced by 10% in 20 years. Over 90% of the near-Earth satellite's breakdown by high-energy cosmic particles occurred over the South Atlantic. According to scientists, the earth's magnetic field weakened to the current level 6,000 years ago, and then gradually recovered. Again, a magnetic field decay process occurred again 3000 years ago. How long will Earth's magnetic field decays, Earth's magnetic field will fail, and humans and nature have any impact? Scientists are not yet able to fully explain these questions. To this end, the “Deutsche Stiftung” carries out a new topic that leads to the Earth
