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。

We're already in the thick of it, but beginning December 12th when Mars moves into an exact square with Uranus and the Moon moves into an exact opposition with Mars, and continuing through December 16th, when the Mars/Saturn square is exact, emotional emissions are even more dramatic—if that's possible.

我们已经几乎处在最危急的时分，而从12月12日开始月亮在双子座准确与火星对冲并与T三角形成大十字触发能量，直到12月16日火星准确与土星相刑，情绪的迸发将以极其戏剧化的方式表现出来。

exact：正确的

重新烹饪一番.在命令列(commandline)上执行gcc时,只要在它的屁股後面加上-On的选项,就能让gcc乖乖的替你生出最佳化後的机器码(outputcode).这里的n是一个可有可无的小整数.不同的gcc版本,n的意义与其正确的(exact)功效都不一样;不过,

exact：精确的

牛顿、拉普拉斯自然观中那种精确的(exact)客观真理论的幻灭又必然引发人们对认知结构本身的反省,于是需要标明的第二个重要质点就是全部人类知识所指归的"或然性"(第2章)了.

exact：精确

在科学史的研究中,同样涉及到如何定义"科学"的问题,对于科学史研究来说,什么样的"科学"定义才是恰当的,而"精确"(exact)的科学史应该研究什么?到底什么样的研究内容才属于科学史的真正研究范围?著名学者戴维.平格里(David Pingree)曾经对古代美索不达米亚,

exact：准确

exact solution：精确解

很不幸的是、任何四维量子场论(除了自由场之外)都没有精确解 (exact solution). 而弱耦合微扰理论(weak couplng perturbation theory)在强交互作用中又不适用. 故此如何得出标准模型(或任何四维量子场论)之非微扰解(nonperturbative solution),
