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。

ATPG is widely used in testing, and in terms of branch-and-bound searching, it is equivalent to a SAT solver. ATPG has two attractive features: It uses structural information of the circuit in decision making, and it handles X states more easily than a SAT solver. This report focus on fast ATPG engine specifically applied to PreImage computing in Unbounded Model Checking.

自动测试激励生成是测试领域的概念，它本身的求解过程是一个等同于可满足性问题的分支限界搜索，它的优点在于可以很好的利用电路的结构信息进行启发式搜索，同时可以灵活的处理不确定位。

However when speaking of the origins of Chinese agriculture before the Han Dynasty, though the author overlooked the links to the Xia, Shang and Zhou dynasties as a result of sectionalism, they were the last modern Homo sapiens who were the branch when moved to China from Africa some 100,000 years ago brought crops and farming techniques. In the past, when agriculture was the major practice, food was vital to ancients.

林俊兴董事长表示，传统中国的农业制度在汉朝逐渐成形，至唐宋发展到巅峰，元明清后逐渐衰败；然而本书在论述汉以前的中国农业起源时，受限其本位主义，忽略了夏商周三部族的祖先，亦是最后一批从非洲外迁的现代智人，於十万年前大迁徙过程中的分支，定居中国之时，自然也带来了耕种作物与技巧。

This system is a kind of Computer Integrated Manufacturing Systems which based on work flow technique, and it uses standard WPDL language to agilely define the check flow in designing process.
