陈景润的”1+2“

陈景润为了能直接阅读外国资料，掌握最新信息，在继续学习英语的同 时，又攻读了俄语、德语、法语、日语、意大利语和西班牙语。
In 1957, Chen jingrun was transferred to work at the sciences institute of Chinese academy . as the new starting point, he becomes more and more hardworking.
这种缩小范围的办法很管用，科学家们于是从（9十9）开始，逐步减少 每个数里所含质数因子的个数，直到最后使每个数里都是一个质数为止， 这样就证明了哥德巴赫猜想
In 1920, Norway's brown proved "9 + 9". In 1924, Germany's pull characteristic Mach proved "7 + 7". In 1932, Britain's ace goodman proved "6 + 6". In 1937, Italy's Tracy has proved that "5 + 7", "4 + 9", "3 + 15" In 1938, Soviet bucher xi too I proved "5 + 5". In 1940, Soviet bucher day proved too I "4 + 4". In 1948, the Hungarian reiny proved "1 + c", which c is a big natural number. In 1956, China's king yuan proof that the "3 + 4". In 1957, China's king yuan has proved that the "3 + 3" and "2 + 3". In 1962, China's PanCheng hole and the Soviet baal baron proved "1 + 5", China's king yuan proved "1 + 4". In 1965, Soviet bucher xi too Bob and small calvino's gravel, and Italian friend Billy proved "1 + 3". 1920年，挪威的布朗证明了“9 + 9”。 1924年，德国的拉特马赫证明了“7 + 7”。 1932年，英国的埃斯特曼证明了“6 + 6”。 1937年，意大利的蕾西先后证明了“5 + 7”, “4 + 9”, “3 + 15” 1938年，苏联的布赫夕太勃证明了“5 + 5”。 1940年，苏联的布赫夕太勃证明了“4 + 4”。 1948年，匈牙利的瑞尼证明了“1 + c”，其中c是一很大的自然数。 1956年，中国的王元证明了“3 + 4”。 1957年，中国的王元先后证明了 “3 + 3”和“2 + 3”。 1962年，中国的潘承洞和苏联的巴尔巴恩证明了“1 + 5”， 中国的王元证明了“1 + 4”。 1965年，苏联的和小维诺格布郝夕太勃拉多夫，及意大利的朋比利证明了“1 + 3 ”。



Natural science is the queen of mathematics, “Goldbach conjecture” is the the pearl of queen's crown .
自然科学的皇后是数学,“哥德巴赫猜想”则是皇后王冠上的明珠！
“Goldbach conjecture ”like a magnet attracts Chen jingrun. From then on, Chen jingrun began to upon the hard journey for the crown's pearl .
哥德巴赫猜想"像磁石一般吸引着陈景润。从此，陈景润开始了摘取皇冠 上明珠的艰辛历程。

学习数论
再筛去不适合哥德巴赫猜想结论的所有那些自然数对之后，如果能够证明 至少还有一对自然数未被筛去，例如记其中的一对为p1和p2，并且p1和p2都 是素数，即得n=p1+p2，这样哥德巴赫猜想就被证明了。
This narrowing range of the way is very useful, so scientists began to (9+9), and gradually reduce the number of each contained which is the number of prime factor, until the each number is a prime numbers , this demonstrates is Goldbach Conjecture.
英国数学家哈伯斯坦和德国数学家黎希特把陈景润的论文写进数 学书中，称为“陈氏定理”，皇后王冠上的明珠也终于被陈景润 所摘取。他站在了科学的顶点
Chen jingrun in addition to conquer the problem outside, and he also in-depth study the combinatorial mathematics and modern economic management, advanced technology and human close relations and so on,get a deep research and discussion. He has been came out more than 70 papers articles in the domestic and foreign newspapers, and have the work of "the mathematics interesting talk about ", "combinatorial mathematics" and so on
1957 年，陈景润被调到中国科学院研究所工作，做为新的起点， 他更加刻苦钻研。
Verification Work : 6 = 3 + 3, 8 = 3 + 5. 10 = 5 + 5 = 3 + 7, 12 = 5 + 7, 14 = 7 + 7 = 3 + 11, 16 = 5 + 11, 18 = 5 + 13,...And so on.
有人对33×108以内且大过6之偶数一一进行验算，哥德巴赫猜想(a)都成立。 但严格的数学证明至今没有人能够给出。
In 1920, Norwagian mathematician Brown come up with a kind of old screen method to prove, and reach a conclusion: each a relatively large even number can be expressed as (9 + 9).
A.每个不小于6的偶数都是两个奇素数之和
B. each not less than 9 the odd Numbers are the suห้องสมุดไป่ตู้ of three odd primes .
b.每个不小于9的奇数都是三个奇素数之和。

In order to directly read the foreign material, and have a good grasp of the latest information, he continues to learn English , he also studies in Russian, German, French, Japanese, Italian and Spanish at the same time.
验证工作: 6 = 3 + 3, 8 = 3 + 5, 10 = 5 + 5 = 3 + 7, 12 = 5 + 7, 14 = 7 + 7 = 3 + 11, 16 = 5 + 11, 18 = 5 + 13, ……等等。
Someone have a checking calculation to 33 x 108 which less than 6 and greater than the one even to check computations; Conclusion prove that "Goldbach conjecture" (a) are established. But strict mathematical proof is so far and no one can be obtained.
1920年挪威数学家布朗用一种古老的筛法证明，得出了一个 结论：每一个比较大的偶数都可以表示为（9+9）。
Brown's screen method train of thought is this:
Any even number (natural number) can write to 2 n, here n is a natural number. 2 n can be expressed as n different forms of a pair of natural number of: 2 n = 1 + (2 n - 1) = 2 + (2 n - 2) = 3 + (2 n - 3) =... =n+n 布朗筛法的思路是这样的： 任一偶数(自然数)可以写为2n，这里n是一个自然 数。2n可以表示为n个不同 形式的一对自然数之和： 2n =1+(2n-1) =2+(2n-2) =3+(2n-3) =… =n+n
In 1966, Chen jingrun proved "1 + 2".
1966年，陈景润证明了 “1+2 ”。
British mathematician Mr Halberstam and German mathematician LiXi specially write the Chen jingrun's thesis writing into math book, called "chans theorem", the queen in the crown of the pearl also be got by Chen jingrun ,he stand in the scientific vertex.

Chen jingrun's character 陈景润的性格 Infatuated with mathematics 小数学迷 Little words 不善言辞 Sincere and good 真诚和善
Then screen out which number is not suitable for goldbach conjecture's conclusion, later, if can prove that there is at least a pair of natural number which is not screen out, for example, to remember one of the pair is p1 and p2, p1 and p2 is prime, vested n = p1 + p2, such goldbach conjecture is proved.

Goldbach conjecture can be roughly divided into two guess:
歌德巴赫猜想大致可以分为两个猜想：
A. each not less than 6 even is the sum of two odd primes
