In this paper, conventional testing methods were summarized. An interferometer was designed based on the schematic of zone-plate with a total optical path for testing aspheric surfaces.

本文针对非球面高精度检测，在总结现有检测方法的基础上，设计了基于波带板干涉法的共光路干涉系统。

The quake happened along a seam in the planet's surface where the Pacific Ocean floor is diving beneath the tectonic plate carrying northern Japan (see 'Collision zone').

这次地震是沿着地球表面的一条缝隙发生的。 在这条缝隙处，太平洋板块正俯冲入另一地壳板块下部，而这块地壳板块正承载着日本的北部地区（见”碰撞带“）。

This is called a subduction zone when one plate subducts beneath another.

当一个板块向另一个板块下俯冲时，那里就被称为俯冲带。

Euro-zone policy makers should consider whether they don't have enough problems on their plate without adding to them.

Where the Pacific plate collides with the Indo-Australian plate, it is forced downwards into the trench, a subduction zone, and the volcanoes are carried with it.
