In this paper, we point out that there exists a logic problem to calculate the area of circulardisc in many textbooks of calculus.
本文中我们首先指出在现行很多“析”和“高等数学”教材中出现的计算圆的面积存在逻辑循环的问题。

The multiple reflection within the circulardisc provides a design feature to reduce the influence of non-total internal reflection and significantly improves the measurement linearity.
