地磁场变化的群阵观测线起自男鹿,通过宫古,横跨日本海沟。测量资料的陆地部分由地壳电阻率研究组提供,而海底部分则由加利福尼亚大学和东京大学提供。研究中,首先对每个测点求其周期为60分钟以及15分钟的地磁变换函数,尔后进一步考虑能对于上述函数作出解释的二维电阻率模型。这次研究的独到之处是把以往计算中所忽略 Geomagnetic field changes in the array of observation lines from the male deer, through the Miyako, across the Japanese trench. The terrestrial portion of the survey data is provided by the Crust Resistivity Study Group, while the seabed portion is provided by the University of California and the University of Tokyo. In the study, first, for each measuring point, find the geomagnetic transform function whose period is 60 minutes and 15 minutes, and further consider the two-dimensional resistivity model that can explain the above function. The uniqueness of this study is neglected in the past calculations
