下扫描 meaning in English

down sweep

The paper currency sorter developed by designer plays an important role in bank area . due to the reason of low resolution of paper currency image and high speed of paper currency sorter , so how to recognize paper currency under these conditions is a key problem
在进行纸币图像识别时,由于采集到的图像是在低分辨率下扫描得到的,如何在这种低分辨率条件下实现对纸币进行识别,并且识别速度要满足清分机的要求,是纸币识别的核心问题。
In chapter three , the mechanism responsible for scanning probe field - induced oxidation in ambient air is attributed to an electrochemical process , i . e . , anodic oxidation or anodization , after the analyses is given of a surface of a sample exposed to air . the effects of biases , tip speeds on morphology of field - induced oxidation , are introduced and deduced in the form of kinetics formula of oxidation growth
第三章首先通过分析大气环境下扫描探针场致氧化加工的基本特性，得出扫描探针场致氧化的加工机理为电化学阳极氧化反应；引进大气状态下场致氧化的动力学方程，推导出偏置电压与场致氧化物的几何形态两者之间的关系、扫描探针移动速度与场致氧化物的几何形态两者之间的关系。
