One assumption was that stripes affect the flies' optic flow via a process known as the aperture effect.

一种假设是条纹通过一种称为孔径效应的过程影响苍蝇的光流。

Once we'd lost the aperture effect as a possible explanation for how zebra stripes affect fly behaviour, we then had to turn to other suggestions.

一旦我们失去了孔径效应作为斑马条纹如何影响飞翔行为的可能解释，我们就不得不求助于其他观点。

But crediting the aperture effect's ability to discombobulate biting flies appears to be flawed-because the researchers found that checked surfaces were just as effective at repelling flies as were stripes.

但是，认为孔径效应能够让叮咬的苍蝇感到困惑似乎是有缺陷的——因为研究人员发现，格子状的表面和条纹状的表面在驱赶苍蝇方面同样有效。
