当今世界上正出现一种极限运动热。所谓极限,顾名思义,它是最高限度的意思。但从数学角度解释,就显得复杂些。极限是数学上的一个概念,即在一定条件下,极限是存在的。当变量x渐变化,趋近于定量a,即它们的差的绝对值可以小于任何已知的正数时,定量a叫做变量x的极限。例如,当圆内接正多边形的边无限增加时,其面积的极限等于圆面积。数学不仅有条件地承认某种极限的存在,而且可以演算、验证。 然而,体育运动的极限却不象数学概念那样明确,那样斩钉截铁,因为这无法用数学的原理加以演算、验证。谁能说出男子100米跑的速度极限是多少?不能。我们只能说,目前最快的速度是本届奥运
An extreme sports fever is emerging in the world today. The so-called limit, as the name suggests, it is the highest meaning. But from a mathematical point of view, it is more complicated. Limit is a mathematical concept, that under certain conditions, the limit exists. When the variable x is gradual, approaching the quantitative a, that is, the absolute value of their difference can be less than any known positive number, the quantitative a is called the limit of the variable x. For example, the limit of the area is equal to the area of the circle when the sides of the circle connecting the regular polygons increase indefinitely. Mathematics not only conditionally admits the existence of certain limits, but also can calculate and verify. However, the limits of sports are not as clear as the mathematical concept, so determined, because it can not be calculated using mathematical principles to verify. Who can tell the speed limit of men’s 100-meter run? We can only say that at present the fastest speed is the current Olympic Games
