The tail is hydrophobic, which means it repels water and instead attaches itself to oils or fats.

尾巴是疏的，这就意味着它可以排斥分子，而是附着在油脂上。

Their tails, which are similarly repulsed by water, compete for space with the lipids that make up the virus's shell.

它们疏的尾部会与构成病毒外壳的脂质争夺空间。

I coated this glass with a hydrophobic coating that does just that.

我用给这个玻有那个功能的疏涂层。

If that angle's more than 150 degrees, then it's superhydrophobic.

如果那个角超过150，那么该表面就是超疏的。

But most of what makes water roll off a duck's back are these superhydrophobic microstructures.

但从鸭背滑落的主要因素，正是这些超疏的微观结构。

Experts suspect the surfaces may be covered with some kind of hydrophobic material that repels water molecules.

专家揣测其表面可能覆盖有排斥分子的疏材料。

When you surround a coronavirus with water, the hydrophobic effect gives the bonds within the membrane their strength.

当你用裹住新冠病毒时，它的疏效应会膜内结构更坚不可摧。

The pepper extract sample goes into a column that's packed with hydrophobic particles that attract capsaicin.

辣椒提取物样本进入一根装满疏颗粒的柱子，这些颗粒会吸引辣椒素。

And so the drop just pulls itself into this round shape and we get a really large superhydrophobic contact angle and that water just ends up rolling right off.

因此，滴会自行收缩成圆形，形成极大的超疏接触角，最终滴会直接滚落。

These surfactants have their hydrophilic head and their hydrophobic tails, and so they form these micelles around the dirt, which is what grabs onto dirt and oil, and helps it to remove it from the hair and the scalp.

这些表面活性剂有亲的头部和疏的尾部，所以它们在污垢周围形成胶束，这些胶束可以吸附污垢和油脂，并帮助它们从头发和头皮上清除。
