| 摘 要： | 研究了沉积在分形基底上的弥散边缘型分形金薄膜的边缘对三次谐波系数以及临界电流的影响．结果表明，该薄膜系统的三次谐波系数、电阻率以及临界电流之间仍存在指数式临界关系．但由于边缘的影响，其临界指数与其它薄膜系统的相应值之间存在着较大差别．还对这些临界规律的普适性问题进行了讨论

| Abstract: | The fringe effect on the third-harmonic coefficient and critical current of the fractal diffuse-fringe Au-film system, deposited on fractal substrates, is studied. We show that both the critical current and the film resistivity as exhibit functions of the third-harmonic coefficient exponential critical behavior. However, the critical exponents in the fractal diffuse-fringe Au-film are obviously different from those of other film systems. A discussion of the universality problem is also presented. |
