在這篇論文之中, 我們討論一些三元碼的性質.
而某些三元碼的性質已經被發現(見[2]). 在第二章,我們討論一些三元碼在 d-語言 之中.
在第三章,我們討論一些碼的結果在 Fibonacci 語言 之中.

In this paper, we discuss some properties
on codes with three elements. Some characterizations for codes consisting of three
d-words are found in [2].
In Section 2, we discuss the codes with three
elements in d-languages. In Section 3, we present some results of codes
in the Fibonacci languages.
