1·In order to preserve the relative intensity in - formation in raw seismic data, we can consider the sea-bottom reflection as reference layer to estimate the compensation value of target stratum.
为了保持原始地震记录的相对强度，可以稳定的海底反射波作参考层，估算目的层的补偿值。
2·Some elementary anomalies of indium and other elements have been found at the bottom of the stratum, it can be used as the evidence to separate geological era.
前人在该套地层底部发现了铱等元素异常，认为可作为划分其地质时代的依据。
3·The model stratums mainly included miscellaneous filling soil surface, interaction stratum of silty clay, silt and fine sand and pebble round gravel at the bottom of station tunnel.
模型介质材料分别模拟地表杂填土层，粉质黏土、粉土、粉细砂互层和车站隧道底部的卵石圆砾层；
