Aimee Mann - Momentum Oh, for the sake of momentum I've allowed my fears to get larger than life And it's brought me to my current agendum Whereupon I deny fulfillment has yet to arrive And I know life is getting shorter I can't bring myself to set the scene Even whin it's approaching torture I've got my routine Oh, for the sake of momentum Even thought I agree with that stuff about seizing the day But I hate to think of effort expended All those minutes and days and hours I've have frittered away But I can't confront the doubts I have I can't admit that maybe the pas was bad And so, for the sake of momentum, I'm condemning the future to death so it can match the past

Aimee 曼-动力哦，为了动力我已经允许我的恐惧比生活大而且资讯科技被带我去我的现在议程因此我否认实现还没有到达而且我知道生活正在很比较短我不能带来我自己设定现场甚至金雀花资讯科技正在接近拷问我已经得到我的常式哦，为了动力甚至认为我同意那一种东西有关抓住那天但是我憎恨想到被花费的努力整那些数分钟和数天和数小时我已经逐渐浪费离开但是我不能面对我有的怀疑我不能承认，也许不好很坏而且如此，为了动力，我正在判刑对死亡的未来因此它能相配过去

AKO occurs when a boxer is knocked down to the canvas and cannot get up before the referee counts to ten.

Another area of study is size, which leads to the cardinal numbers and then to another conception of infinity: the aleph numbers , which allow meaningful comparison of the size of infinitely large sets.

Plane analytic geometry is a important content in the mathematics curriculum of high school, which embodies powerful function of analytic method and algebraic method in the depicting curve. It reflects important idea of the combination of number and figure. Learning the course is very important for students to improve mathematics thought ability. Teachers and students are engaged in teaching and learning by the textbook, so it is necessary to analyse plane analytic geometry textbook.

平面解析几何是高中数学课程中的重要内容之一，它体现了解析方法和代数方法在刻画平面曲线方面的强大作用，反映了数形结合的重要思想，学习这部分内容对提高学生的数学思维能力具有十分重要的价值，师生正是通过教材这一载体从事教学和学习活动的，因此，很有必要对平面解析几何教材进行分析。

For a general parametric curve/surface, we usually cannot compute its exact implicit form. Even though its exact implicit form can be computed, the curve/surface implicitization involves relatively complicated computation and the degree is higher. Moreover, it may have unexpected components and self-intersections. All these unsatisfied properties limit the applications of the exact implicitization. So finding curve/surface approximate implicitization has become a practical problem. In this paper, we present an algorithm to solve the approximate implicitization of a given parametric curve by using a quadratic algebraic spline curve.

由于精确隐式化过程不一定可以实现，即使可以实现隐式曲线曲面的阶数高计算复杂，并且具有不希望的自交点和奇异分支，从而限制了隐式化的运用，所以寻求参数曲线曲面的近似隐式化问题成为很实际又重要的问题，提出利用二次代数样条曲线来实现一般平面参数曲线近似隐式化的一种算法。
