工作学习 / IT技术讨论 / 请问各位DX一个技术问题：集肤效应(Skin effect)和频率是什么关系？

这不是IT问题。GOOGLE是个好东西。

频率越高越明显。

Follow this link: http://signalintegrity.com/pubs/news/skineffect.htm or borrow any textbook in E.M. theory.

Thank you! Who said that this is not an IT problem? The question was written by an engieer of Intel Corp.

安沦落风尘作了IT还要被你无端纠缠好惨！

俺也一样惨，集肤效应刚刚搞明白一点，又看见了临近效应。:((

正解：δ=1.98(ρ/fμ)1/2 mm
1/2为开平方。
δ:standard depth of penetration(mm)
ρ:material resistivity(μohm-cm)
f:test frequency(hertz)
μ:relative permeability(a dimensionless quantity and equal to 1 for non-ferromagnetic material)

谢谢楼下的自由人。这篇文章刚读完，怎么没说是什么温度的公式用2.61？不同温度的电阻值相差很大。:((

集肤效应和频率的关系是，使用名牌化妆品，使用频率越高，皮肤吸收得越快，也就是集肤效应越好。
