Each observation could have been weighted inversely as the distance or as the square root of the frequence.
每次观测可以倒过来加权作为距离或作为频率的平方根。

Both seismological theory and macroseismic observation show that the shape of strong motion response spectrum depends mainly on magnitude, distance of epicenter and engineering site condition.
