摘要
文章简介对数螺线在自然界中的存在性态及其在科学领域中的应用.继而,借助于质点运动学的自然坐标系和极坐标系,相应推演出对数螺线的解析表达式.
This paper introduces the logarithmic spiral curve which exits in the world, and its application in science and technology. Furthermore, by means of the natural and polar coordi-nate systems of particle kinematics, we deduce the analytical expression of the logarithmic spi-ral curve.
