因其内部通常采用压电陶瓷叠堆和柔性铰链支承的组合一体式机械设计结构，使得压电工作台具有微位移分辨率高、稳定性强等优点。

Its interior usually USES combined integration machine design structure of piezoelectric stack and flexible hinge, which enabling piezo-stage has high position resolution and stability.

结果：电子束ct使用电子束的磁偏转代替球管机械运动，既加快扫描速度，又减少机械磨损，有很高的时间分辨率。

Results EBCT had the advantage of high speed in scanning and high resolving power of time without mechanical abrasion due to the using of electron beam.
