The Delboeuf illusion is so convincing that studies have found you'll actually feel more full when you eat a meal from a smaller dish.

德尔博夫错觉非常具有说服力，经研究发现，用较小的餐具吃饭实际上会感觉更饱。

In the Delboeuf illusion, if one of the circles is surrounded by a third circle that's just a little bigger, the inside circle will look larger than its twin.

在德尔博夫错觉中，如果圆圈被第三个较大的圆圈包围，那个圆圈就显得比另一个大。
