Through experiment, KNO3 is thought a better electro-polymer medium, Moreover. the good parameters of scanning number. Scanning rate and scanningvoltage range were determined.
通过实验，确定KNO3为较好的电聚合介质，以及较好的扫描速率、扫描次数、扫描电压范围。

Scanning tunneling microscope (STM) work by the voltage added to the microscope probe tip and the ends of the scanned object and then detect current changes.
扫描隧道显微镜(STM)的工作方式是把电压加到显微镜探头尖端与被扫描物体这两端，然后检测电流变化。

An STM works by applying a voltage between the microscope's tip and the material it is scanning, and then monitoring the change in current.
