一、引言汉字输入的方法目前可分为二大类,一类是大字盘方法,另一类是代码法.由于大字盘方法缺点很多,而代码输入法可以采用国际通用的电传“打字机”作为输入键盘,所以,现在国内外主要研究汉字代码输入法. 所谓代码法,就是用数字或字母来代表汉字.目前已有的汉字编码法,从原理上讲可分为三类,号码法、拼音法和拆字法. I. INTRODUCTION The method of inputting Chinese characters can be divided into two major categories at present, one is the method of the big dial and the other is the code method.
