This paper introduces the double-structure element edge detection algorithm base on morphology edge. This algorithm provides a new morphological operator to detect single pixel width edge in an image.

由此，可以根据这些性质建立类似一般性的差分算子的形态差分算子来进行边缘检测。

The native structure is this double stranded structure here and if I heat it up slightly and I add some base, so under slightly basic conditions, these molecules will fall apart because you've created conditions where the hydrogen bonding is no longer favorable so they peel apart.

原始结构,在这里就是指DNA双链,如果我稍微加热,并且加入一些碱,在弱碱性的条件下,这些配对碱基会分开,这是因为在一定条件下,碱基对之间的氢键,不再稳定并且会断裂分开
