For example, you are probably familiar with the number called "pi". This irrational number is so important that we give it a name and a special symbol!

The Greek mathematician merely regarded that number as an interesting irrational number, in connection with the middle and extreme ratios.

一书中，希腊数学家仅仅是把这个数当成一个与外比和中比相关的有趣无理数。

First, let's consider the number seven: In mathematical terms, it is an irrational number, i.e., a number that cannot be represented as a simple fraction, a number that is "uncountable." To the mind of the symbolic thinker, the number is associated with all that is strange and unusual.

首先，让我们认识一下数字7；在数学上，它是一个无理数，也即除以它的结果不能得到一个单一的数字，除以这一数字将得到一个无穷数列，对一个符号象征思想家的内心来说，这个数字会让人联想到所有古怪的，不寻常的事物。

The decimal form of an irrational number is a non-repeating and non-terminating decimal number.

More than two thousand years ago, when greek found that there existed another kind of number likewhich is totally different from rational number. they can't accept this weird fact and thought this new kind of number was unreasonable, so people called it "irrational number".

两千多年前，当希腊人发现这类数与有理数不同时，人们难以接受这个事实，认为这个怪物的出现是不合情理的，于是给它扣上一顶无理的帽子，原有的数自然是有理的。

At last, a method on creation and calculation of a kind of irrational number is researched. The digit number of the extension of this irrational number is random on certain basis. Therefore, a stream cipher is designed, which uses the extension digit of the irrational number as the key stream.

最后本文在研究一种无理数的生成方法和计算方法的基础上，利用该类无理数在某基底的展开序列中各个位的数字具有良好的随机统计特性的特点，提出了一种以这类无理数的展开数字流作为密钥流的序列密码设计方法，并对生成的密钥流的统计特性进行了分析和测试。

Moreover, by discussing the role of geometrical proof in Ars Magna and Cardano's attitude on irrational number, negative number and imaginary number, the paper points out that the role of geometry in Renaissance algebra had been tending weaker.

同时，通过考察几何证明在《大术》中所起的作用以及卡尔达诺对无理数、负数和虚数的处理，指出在文艺复兴时几何在代数学中的作用己逐渐减弱。
