反素数的定义:对于不论什么正整数,其约数个数记为.比如,假设某个正整数满足:对随意的正整 数.都有,那么称为反素数. 从反素数的定义中能够看出两个性质: (1)一个反素数的全部质因子必定是从2開始的连续若干个质数.由于反素数是保证约数个数为的这个数尽量小 (2)相同的道理,假设,那么必有 个人理解性证明: 对(1)如果不是从2開始,那么如果n的最小素因素是k,把k换成2,2的次数仍等于k的次数,得到N,可知,N<n,而且f(n)==f(N).与n是反素数矛盾 对(2)如果ti<tj   ti,…

WPF中的常用布局   一 写在开头1.1 写在开头微软是一家伟大的公司.评价一门技术的好坏得看具体的需求,没有哪门技术是面面俱到地好,应该抛弃对微软和微软的技术的偏见. 1.2 本文内容本文主要内容为WPF中的常用布局,大部分内容转载至https://blog.csdn.net/woshisunjiale/article/details/54136323,代码片段可能有所不同. 二 WPF中的常用布局因为项目需要,所以得学习WPF开发.WPF使软件界面和逻辑相分离,手写xaml进行程序UI的开…
