This article makes a wide and common conclusion by studying the divisibility of the prime number,the judgement of the prime number,continual prime number and the prime number array,which brings convenience to further study on the judgement of it and the search of its concerned characters.
质数是整数中一类比较特殊的数,对于质数的某些特殊性质的研究具有广泛的意义,本文通过对质数的整除性、质数的判断、连续质数、质数数列特点的探讨,从而总结出了一般广泛的结论,为我们判断质数以及寻找它的相关性质带来方便。

if m≡1 (mod4), shown properties of Garssin integraldomain R(m~(1/2)) = Z[ω] Structure of quotient rings and critical condition of prime algebraic integral number.
当m≡1(mod4)时,证明了高斯整环R(m~(1/2))=Z[ω]的一些性质:R(m~(1/2))的商环的结构和R(m~(1/2))中质代数整数的判别条件。
补充资料：质数
又称“素数”。在大于1的自然数中，除了1及其本身以外不再含有别的因数的数。如2，[kg*4]3，[kg*4]5，[kg*4]7，11，…。早已证明质数有无穷多个，但一直没找到表达它的通项公式。到1983年为止，已发现的最大质数为mp=2p-1，其中p=86243。大于1的自然数，至少有一个因数是质数。
