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。

Moreover, it was successfully linked with lactobionic acid through amine groups on the surface of particles, and used to recognize living liver cells successfully.(3) In order to simplify the proceeding of preparation of silica-coated qdots, a novel one-pot method using 3-mercaptopropyl-trimethoxysilane as a capping molecule was proposed for the first time. Furthermore, amine and phosphonate groups were also modified on the surface of silica-coated qdots simultaneously. This was the first time the synthesis and the surface modification of qdots were performed in the same system.
