这些结构在早些年曾被回声探测器探测到，但是它们从未被钻探过。

These structures had been detected years earlier by echo-sounding instruments, but they had never been penetrated in the course of drilling.

实验采用单光路临界角法，用四象限探测器探测输出信号，物面微位移采用压电陶瓷作为驱动元件。

The experiment came into use single light path critical angle method, output signals were detected by four-quadrant receiver, micro-displacement drive element were piezoelectric ceramics.
