查询词典 prime number

In additive prime number theory,a classical result of Hua states that,every suffi-ciently large odd number N can be represented as 〓,where 〓 is aninteger and 〓 are primes,which can be regarded as an extension of Goldbach-Vinogradov Theorem.

堆垒素数论中一个经典的结果是华罗庚教授证明的：任一个充分大的奇数N都可以表为N=〓+〓+〓，其中λ是一正整数，p1，p2，p3是素数，这一结果可以看作著名的Goldbach-Vinogradov定理的推广。

This essay has applied the characteristics of sine functions of Goth function, and according to Kronecher function, it has set up a new function to represent composite number and thus come out with a more accurate function of prime number distribution .

本文根据表哥德巴赫猜想定义了卷和函数，并依照素数分布的函数得到了表哥德巴赫猜想的函数形式。

Or for short: A prime number is a natural number with exactly two natural divisors. A natural number that is greater than one and is not a prime is called a composite number.

用通俗的话说，就是大偶数=素数+素数*素数或大偶数=素数+素数（注：组成大偶数的素数不可能是偶素数，只能是奇素数。

Every integer can be written uniquely as a product of prime factors, and that because the Fermat number are co-prime, each prime number can appear in at most one Fermat number.

每个整数都可以被独特得分解质因数，而且因为费马数是互质的，每一个质数最多只能在一个费马数中出现。

A second subnumber is calculated for the second number as the multiplicative inverse of the first number with respect to a second submodule (120) that equals the second prime number minus 1, the first submodule and the second submodule being relatively prime.

计算该第二数的一个第二子数做为该第一数的相对于一个第二子模数(120)的一个倍数逆数，该第二子模数等于第二质数减1，第一子模数与第二子模数互质。

In prime number distributed research process,and through established one kind of new sieve method and the stair theory,this article obtained about three group of prime number distribution recurrence formula: The 1st is not bigger than x the prime number integer recurrence formula;The 2nd is not bigger than x the twin prime integer recurrence formula;The(3rd Recurrence) formula.

在研究素数分布过程中，通过创立一种新的筛法与台阶理论，得到关于素数分布的三组递推公式：不大于x的素数个数与孪生素数对数量的递推公式；不大于x的孪生素数个数的递推公式；任意偶数x≥6表为两个奇素数之和与孪生素数对数量对数的递推公式。

It is very difficult to discrimnate a natural number to be a prime number by J Wilson s theorem This paper presents another method for discriminating prime number .

本文给出关于质数一个判定准则：数P为质数，当且仅当P不能表示为四个自然数之和，使其中的两数之积等于其余两数之积

What is the largest prime number less than 2007 Prime number have only 2 positive factors, e.g.

请问少于2007的最大质数是多少？质数只有两个正因子，例子：2、3

Two years ago, at the age of 18, Rytis Slatkevicius launched a project called PrimeGrid, which has since assembled possibly the largest database of prime numbers in the world, and has broken several records: last August, for example, it found the biggest known example of a special kind of prime number called a Woodall prime.

两年前，18岁的瑞希斯·斯拉特科维西尔斯启动了一个叫做PrimeGrid的项目，从那开始，这个项目就尽可能地收集着世界上存在的质数，从而成就最大型的数据库，而且该项目还打破了好几项记录：比如说2006年8月，该项目发现了一种特别类型质数（称为Woodall prime）的最大的已知样本。

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子："据报道，美国利用转基因技术，将一种病毒的DNA分离出来，与另外一种DNA进行结合，拼结成一种剧毒的"热毒素"生物战剂，且私下有人透露，这种生物战剂只需20克，就可以导致全球60亿人全部感染死亡。"
