5) Geomagnetic paleointensity
古地球磁场强度
6) paleointensity of the geomagnetic field
地球磁场古强度
1.
It is unveiled that during most of the Mesozoic (200~100 Ma) the paleointensity of the geomagnetic field was very low, only one-third of the mean Cenozoic value, that the geomagnetic field shows no reversals from 124 to 83 Ma, and that the true polar wander (TPW) almost remained a standstill from 170 to 110 Ma.
本文介绍了90年代以来地球物理学在地球磁场方面(地球磁场古强度,地磁场极性反转频率以及真极移)的研究成果,揭示了200～100Ma全球低的地球磁场古强度;124～83Ma低的极性反转频率以及170～110Ma近乎停滞的真极移。
补充资料：球场
1.供打球用的操场，也用于军事操练。古时打球本军中之戏，主要有步马二种。步打者古谓之蹴鞠﹑蹋鞠;马球之戏，则树旗击鼓，无异演武习战。唐以后谓鞠为球，故称球场。 2.今指篮球﹑足球﹑网球等球类运动所用的场地。
