In the history of chinese linguistics, Shuo Wen Jie Zi of Xu Shen is the first Chinese characters Dictionary. This book analyzes the shape of Chinese characters, and reveals the meaning of Chinese characters, and expressed the sounds of Chinese characters. To young scholars so far one of the most influential classics. Among those reasons are the achievements of the initiatives the system of radicals. 'The system of 214 radicals' which we use today is due to the shape classification. In contrast, Xu Shen's 'The system of 540 radicals' classification is based on the meaning of Chinese characters. The first cause of change to 'the system of 214 radicals' is due to the change in shape of Chinese characters, and the second reason is in order to conveniently search Chinese characters. However, At the same time, 'The system of 214 radicals' has also contradicts away from the system of radicals's original purpose. To overcome the contradictions and to raise rational and scientific alternative, I want to track and analyze radicals disappeared from Xu Shen's 'The system of 540 radicals'. Based on the Xin Hua Zi Dian, the number of lost radicals is 333 radicals. In the first step of the study to achieve the ultimate purpose, this paper is a study of 36 radicals without Any Connected Characters in Shuo Wen Jie Zi. Through analyzing the changes and belonging, I want to stand out the principles for the alternative in it.
