摘要
圆锥对数螺线是圆锥面上的斜驶线,它在无线电天线设计中有实际的应用。本文在推导圆锥对数螺线方程的基础上推证了它的一系列性质,揭示了这条曲线的几特征。
The logarithmic spiral of cones is a loxodrome on the cireular conical surface.They find appication in the design in the wireless antenna.On the basis of equation of logarithmic spiral of cones,the author proves a series of its properties,revealing the geomtric features of this curve.
