形如2λpα+1的质数模原根的直接算法

东北师范大学学报自然科学版1979年第一期和1980年第二期上，李复中教授给出了部分质数模全部原根的求法，今天我们称它为间接求法。近年来，国内外没有这方面的论述。作者通过大量的数据推演和论证，做出了形如2^λP^α＋1的质数模全部原根的直接算法（定理），并给出了这类质数模全部原根的递推公式。这种直接算法对于求2^λP^α＋1的原根更具有灵活性，并减少了计算原根一半的计算量。

Direct Algorithm of Original Root Like Prime Number Mould

On the first volume of 1979 and the second volume of 1980 of the gournal of North-east Teacher's Unirersity,Professor Li Fuzhong stated all kinds of ways to work out some of prime number mould original roots.Now we call it indirect algorithm.By looking for information,the author found out that there is no such state ments about it at home and abroad.The author has found out the direct algorithm of all original roots like prime number mould by lost of data inferences,mathematical calculations and demonstrations and gives out the recurrence formula.This method is very flexible for culculating the original roots of,and it can save half of the work..
