磁場倒轉 的英文怎麼說
中文拼音 [cíchǎngdǎozhuǎn]
磁場倒轉
英文
magnetic reversal-
Only on rare occasions do the thermodynamics work ; the fluid motions and the magnetic field all evolve in a compatible manner, so the new dipole polarity can diffuse in and establish a reversed magnetic field
只有在很少的情況下熱力學才發揮作用,此時流體運動和磁場都會以相互訪調的方式演化,這樣新的偶極性就會散開並建立一個倒轉的磁場。The magnetic reversal of the poles
磁場磁極的倒轉Occasionally, however, the dipole part of the field reverses, causing the locations of the north and south magnetic poles to switch
不過,有時候磁場的偶極部分會倒轉,導致了北磁極和南磁極的位置轉換。So the rare field reversals are most likely caused by larger changes in the flow in the outer core, or in the way in which the field lines are wound into the flow by diffusion
這樣,不經常發生的磁場倒轉,很可能是由外核流體或磁場曲線通過擴散宛然進人流體方式發生較大的變化而引起的。This paper introduces the formation of magnetic field, polarity reversal, secular variation and the use of geomagnetic polarity reversal or susceptibility in stratigraphic study
摘要本文介紹了地球磁場的成因、極性變化以及運用極性倒轉劃分對比地層和指示環境。Fluid motions try to reverse the field on a few thousand years timescale, but the solid inner core tries to prevent reversals because the field cannot change ( diffuse ) within the inner core as quickly as in the fluid, outer core
盡管流體運動會在幾千年的時間尺度上使磁場倒轉,但因為磁場的變化(擴散)在內核里不能與在外核的流體中一樣快,所以固體的內核會盡力阻止倒轉。We know from magnetic records locked in rocks that the earth ' s magnetic field has reversed many times in the past
我們從鎖定在巖石中的磁記錄中知道,地球磁場在過去倒轉了很多次。In order for a reversal to take place there must be a brief time during which the field is non - existent
為了發生一次倒轉,必須有一個很短的時間沒有磁場存在。We also know that the magnetic field of the sun reverses as well every 11 years, whereas the earth ' s reverses irregularly
我們還知道太陽的磁場也發生倒轉? ?每們年一次,而地球磁場的倒轉並無規律。分享友人
