摘要把紧密相连的圆环构成的圆盘以渐开线展开成等面积的直角三角形，得出了较为直观的由周长和半径表示的圆面积公式。
The disk, which is composed of continuous annuluses, can expand equivalent trangle by asymptotice line. We can obtain the circular area which is visually expressed by circumference and radius.
因此，由于衍射存在，我们很难把入射光线集中在一点上，衍射使最终形成一个圆盘或者在外圈形成一个圆环。
Therefore, instead of incoming light being focused to a perfect geometric point, the diffraction effect spreads the light into a disc with rings surrounding it.
