They're naturally hydrophobic, meaning they won't absorb water.

它天生就具疏水性，意思是它不会吸收水分。

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

给这玻璃加了有那功能的疏水涂层。

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水分子的疏水材料。

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

尾巴是疏水的，这就意味着它可以排斥水分子，而是附着在油脂上。

Here's what they saw. The leaves are extremely hydrophobic, meaning water beads up to minimize contact with the surface.

以下是察到的情况。叶片极其疏水，这意味着上面的水会形成水珠，尽量减少与叶面的接触。

The fats in your pastry dough are hydrophobic, meaning the butter and oil molecules don't like binding with water.

酥皮面团中的脂肪具有疏水性，这意味着黄油和油分子不易与水结合。

These acids and their salts have both hydrophobic and hydrophilic sides, making them amphiphilic, which help them make cholesterol and fat in the gut more soluble in bile.

胆汁酸和胆盐同时具有疏水性和亲水性，即两亲性，得益于此，胆汁可以更好地溶解肠道中的胆固醇和脂肪。

And it turns out that microscopically rough surfaces tend to be more hydrophobic, because they can trap pockets of air and minimize the interaction between water droplets and the surface of the material.

结果显示，显微镜下，粗糙的表面拥有更好的疏水性，因为它可以捕捉气囊，最小化水滴和物质表面的相互作。
