查询词典 implicit

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。

In this research, a system of various levels of task difficulty was set up by a complex rule. Three characteristics of implicit learning were detected with this system: 1 Implicit learning didn't work under the condition of the most difficult task. 2 When the task became easier, implicit learning started working on some level of task difficulty. 3 The efficiency of implicit learning would become higher if the task became easier; but there was a limit to the efficiency of implicit learning.

本研究利用自行设计的复杂规则产生出不同难度的任务系统，进而通过实验阐明了内隐学习的三个特征：在任务难度极大的情况下，内隐学习并不发挥作用；在任务难度降低到一定程度的时候，内隐学习开始发挥作用，这仿佛是一个"阈限"；随着任务难度逐渐降低，内隐学习的效率也随着提高，但是最终停止在一个较高的水平而不再继续上升。
