That is the barest minimum, but $50,000 provides a much safer flyingaltitude.
这是最低的要求了,50000元会保证更安全的飞行高度。
2
The first is to interpret the time-domain airborne electromagnetic data measured at different flyingaltitude so that the earth resistivity will be provided.
其一是解释在不同飞行高度测得的时间域航空电磁法资料,从而提供大地电阻率;
3
The second is to estimate the time-domain airborne E. M. response, if the earth resistivity is given; therefore the pseudo-anomalies caused by the change of the flyingaltitude will be corrected.
