摘要
用实数圆建立了一个关于"∞"的几何模型,得到了最小和最大的两个广义实数——左无穷和右无穷,并给出数中带左右沿的广义实数系R∞,指出了人们对"∞"认识上的一些误区及潜无穷对极限理论的消极影响,消除了极限中表述的矛盾。
Using real number circle to establish a geometric model about '∞',got two minimum and maximum number of generalized real —— left infinite and right infinity,and gave the number along with left and right generalized real number systemR∞,pointed out some of the mistakes that peoples in understanding '∞' and the negative impact about potential infinite put on ultimate theory,eliminate the contradictions of limit expressed.
