And so, if I go counterclockwise around this region, basically I go counterclockwise along the outer curve.

如果沿着区域边界逆时针走，基本上，是逆时针沿着外面的曲线走。

There is no hard and fast rule as to which piece is placed on the top when working with these shapes, but it hat been found that distortion is less likely to occur when the outer curve is uppermost.

当缝合这两种类型的裁片时，就放在上面一层的裁片而言，是不难的且很快就能掌握，但发现缝至弯曲的凸出部位最凸出的部分时，不太容易使其缝合圆顺。

Then, the accuracy of this method and the influence of the outer boundary on the results are discussed. The convergent curve of the capacitance is given.

然后对该方法的计算精度以及人为设置的外边界对计算结果的影响进行了讨论，给出了电容收敛曲线。
