4 感想

“有理数”这一名称不免叫人费解 ，歪单词大悟有理数并不比别的看完数更“有道理” 。事实上，有理英文这似乎是数被一个翻译上的失误
。有理数一词是翻译二四六天好彩(944cc)免费资料大全从西方传来  ，在英语中是歪单词大悟rational number，而rational通常的看完意义是“理性的”。中国在近代翻译西方科学著作，依据日语中的翻译方法 ，以讹传讹 ，把它译成了“有理数”。但是，这个词来源于古希腊，其英文词根为ratio，就是比率的意思（这里的词根是英语中的，希腊语意义与之相同）。所以这个词的意义也很显豁，就是整数的“比”。与之相对，“无理数”就是不能精确表示为两个整数之比的数，而并非没有道理 。
