评《易》学研究中之“雷氏A—D密码”

《易经》６４个复卦，历来均将之一分为二即分解为两个单卦来说明其规律性，而《１０分钟周易》一书则提出用“雷氏Ａ—Ｄ密码”将之一分为三即分解为三个“四象”予以剖析．数学分析表明“雷氏Ａ—Ｄ密码”关于６４个复卦卦象所呈现的某些规律的一套说法确实符合二进制，但总的来说是失多得少，而用它来破译“敦煌古卦”和“中天八卦”也显得证据不力。

Comments on Let's A-D Code for Use in Deciphering Gua Related to Yi (The Book of Changes)

Unlike the traditional schools who had made use of 8 pieces ofsingle Gua to decipher the 64 double Gua related to Yi (The Book of Changes),Let's A - D Code attempted a new decipherment by using the four Xiang's as units. Though mathematically sound, the interpre tations offered by Let's A-D Code involve more losses than gains in comparison with those presented by the traditional schools. Moreover, Let's A -DCode is found to be inadequate when used to decipher either the ancient Gua'sfound in Dunhuang or the eight Gua's named Zhongtian.
