缩尺法求解哥古猜想解答

哥德巴赫猜想与古叶猜想合成哥古猜想（Goldbach—Guye’s Conjecture）：任何一个非零偶数（z），都可表达为两个素数（y及x）之‘和’或‘差’；即有z=y-x，或有z=y-x当知4或z时，如何求解y及x配偶成副呢？文章介绍了一种缩尺法（按照‘计算尺原理’利用‘定尺’与‘动尺’间的相对位移，求解哥古猜想解答），并举例说明了缩尺法的应用特点和注意事项。

Method of Contraction Rule in Solution of Goldbach-Guye's Conjecture

Goldbach＇ s conjecture and Guye＇ s conjecture compose the Goldba ch-Guye＇ s conjecture： any non-zero even number（z） can be expressed as the sum or subtraction of two prime （y and x）：that is z＋=y＋x,orz=y-x.When z＋ or z- is known, how to solve the y and x ？ This paper introduces the method of contraction rule （according to the slide rule principle, applying the relative displacement of fixed rule and moved rule ,Goldbach-Guye＇ s conjecture can be solved）,and explains the features and attentions when adopting the contraction the method.
