- 无穷远点：在射影几何中，保持变换平面上所有角度大小的理想数学点。
1 [数]?无穷远点 第二，我们借由球极投影可以看到，若于平面添加一无穷远点(point at infinity)，则我们就可以得到一个 S2 球面。 2 ?无限远点 用于密码学技术的 椭圆曲线是由满足上述方程式的所有点(x, y)及一个无限远点(point at infinity) O所形成 的集合，其中座标x与y属于某个有限体(finite field)。

The formal definition is that the gravitational potential energy at a point P is the work that I, Walter Lewin, have to do to bring that mass from infinity to that point P. 形式定义就是,它在点P的重力势能,等于我，将物体从无穷远处,移动至点P所做的功。 - 2
The far point of a normal eye is at infinity. - 3
", in fact, at this point, the five name and brand is a very low probability, it is even 0, and relative say others is a probability of fishing alone "infinity", it is not for luck." 实际上此时，五个叫的和牌现张概率极低，甚至为0，而相对说别人单钓的现张概率就“无穷大”，这不能以运气而论。
