And this is why we decided to investigate why is this important in an interfacial property kind of perspective.

此，我们决定从界面的角度来探究其重。

The baby will have this huge interfacial area, but there's nothing to regulate it and to give the optimal properties.

儿将拥有巨大的气液界面面积，但没有任机制来调节这一面积， 也无法赋予其最佳。

So there is this tangential pull between the molecules that will basically define how large is this surface tension that Basically, this shows us how difficult, how much energy it costs to increase this interfacial area.

此，分子间存在一种切向的拉力， 这种拉力基本上决定了表面张力的大小。这实际上向我们展示了扩大这一界面面积有多困难， 以及需多少能量。
