focal depth

基本解釋

The local horizontal dislocation reaches about 4 km in the medium at the focal depth, where the upper mantle rises.
在震源深度附近的介質(zhì)中，局部水平錯(cuò)動(dòng)可達(dá)4公里左右，上地幔頂部在此隆起。
The research result shows the location accuracy by the method is better and improves more than original location result in residual error, evaluated error, epicenter distribution and focal depth.
研究結(jié)果初步表明該方法定位精度比較高，無(wú)論在殘差、測(cè)定誤差、震中分布還是震源深度方面，都比原來(lái)定位結(jié)果有較大改進(jìn)。
