In order to study the popular curve shortening flow in the plane, Gage[3] has shown in 1983 the following inequality, if k is the signed curvature of a closed convex plane curve γ with length L and enclosing area A, then one gets Gage calls it an isoperimetric inequality in [3], but he does not show that the equality holds if and only if the curve γ is a circle, while as an isoperimetric-type inequality, one should prove this kind of result.
Gage称之为等周不等式,但他没有证明其中等号成立当且仅当,γ为圆周,而作为等周型的不等式是应该证明这种结果的,本文我们利用单位速率外法向量流,通过努力证明了这种结果,从而把Gage不等式加强成更加等周的形式。

Rinted-circuit board air-core coils designed by using CAD tools and fabricated by adopting advanced PCB manufacturing technology are good in measurement accuracy and consistence of products parameters. But the characteristics of limited turns-density and large magnetic induction intensity grads on coil cross-section make great influence on the continuous uniform distribution of coil turns along the coil circumference and cause its discrete distribution.
CB空心线圈采用CAD方法设计和先进的PCB加工工艺制造,具有很好的测量精度和参数一致性,但是,线匝密度较小,而且截面上磁感应强度梯度较大,从而影响了线匝沿圆周均匀分布的连续性,使其具有了离散分布特征。
