CURVATURE-BASED INTERACTION POTENTIAL BETWEEN MICRO/NANO PLANAR CURVE AND PARTICLE LOCATED OUTSIDE THE CURVE
《Acta Mechanica Solida Sinica》2015年第4期331-346,共16页Xugui Wang Yajun Yin Jiye Wu Kun Huang Dan Wang Qinshan Fan 
supported by the National Natural Science Foundation of China(Nos.11072125 and 11272175);the NSF of Jiangsu Province(Nos.BK2011075 and BK20130910);the research found for doctor student education
Based on the negative exponential pair-potential (I/R)n, the interaction potential between the micro/nano planar curve and the particle located outside the curve is studied. We verified that, whatever the value of e...
