1·A kind of piezoelectric motor with nano-step, based on the principle of inchworm motion, is introduced in this paper, then a newly developed driving power is presented in detail.

介绍了一种基于尺蠖运动原理的纳米级步距压电电动机，提出了一种新型的压电陶瓷驱动电源，并给出了详细的电路原理图。

2·The authors proposed that the motor USES a similar inchworm mechanism to package the DNA into the virus.

作者假象马达也应用类似“尺蠖”的机制把DNA包装进病毒。
