关于自然数密度问题的再思考

A question about the natural number's density

借鉴数论方法中的密率论及微积分工具,研究了数论中的首位数问题.探讨了首位数在自然数集合中的对数密度,并给出了证明.最后利用Matlab软件作出其规律图像.

Using the density and the calculus tools in number theory as a reference, the question about first number in number theory is analyzed, the logarithmic density of first number in natural number is proved, and its image of regularity is described by using the Matlab software.
