contact potential difference meaning in English

接触电势差
接触电势位差
接触电位差
接触势差

To achieve accurate detection of surface potential , the measurement of the contact potential difference of the zno / si step was also carried out . polarization - related surface properties of ferroelectric thin films were investigated by kelvin probe force microscopy ( kpfm ) , leading to the discovery of asymmetric charge writing on the surface of pb ( zr _ ( 0 . 55 ) ti _ ( 0 . 45 ) ) o _ 3 ( pzt ) thin film
为了优化仪器的检测灵敏度和稳定性,选用氧化锌薄膜上的zno / si台阶作为测试对象,检测了zno / si的接触电势差;通过改变仪器系统参数,发现针尖-样品距离和扫描速度对接触电势差的检测结果影响显著。
The effects of contact potential differences ( cpd ) in the experiments for testing coulomb ' s inverse square law and detecting the photon rest mass based on the concentric metal spheres were discussed , and the ultimate restrictions on hte experimental sensitivities due to cpd were presented for static experiments and dynamic ones respectively
摘要分析基于同心导体球壳方法检验库仑反平方定律和光子静止质量的实验中接触势的影响，并分别给出了静态和动态实验中接触势对实验灵敏度的限制。
