The most active area of the earth surface is plate boundary, where most earthquakes and volcanic distribute on, while the region within the plate is relatively stable.
板块边界是地球表面最活动的地带，绝大多数地震、火山分布于活动带上，而板块内部则是相对稳定的地区。

Taking into account the scale and boundary condition effects of the model, the numerical results have been proved to be a relatively conservative reliable valuation.
考虑模型尺寸效应及模型边界条件的影响，计算结果为相对保守的可靠估计。

Sharp boundary inversion is a relatively difficult problem in magnetotelluric and other geophysical inversion , which has been studied by many researchers.
