摘要:时段、线段的长度具有测不准的性质。线段可以被看作是连接近似点构成的;但不是由理想点构成的,因为理想点没有大小。每一个实数都有它的理想实数,近似实数与全能近似实数(无穷数列)三部分构成。如果要问理想实数√2究竟多大呢,就可以用1.4、 1.414或它的其它近似实数进行近似刻画,但其精确值则是其全能近似实数(无穷数列1.4, 1.41, 1.414, ……)的极限。

Abstract: The length of time segment and line segment possesses the character of which could not accuracy to measure. Line segment may be regard constitution by to link approximation points, but it could not regard constitution by to link ideal points, because ideal points have not the size. Every real number is constituted by its ideal real number, its approximation real number and its omnipotent real number (infinite sequence). If ask the question of that how many the ideal real number √2 is? May be roughly depicted by its approximation real number 1.4, 1.414 or others, but its accurate value is the limit of its omnipotent real number (infinite sequence 1.4,1.41,1.414,……).
