Much smaller than that box I just drew.

接触面的粒子会怎样。

A second major factor has to do with surface area.

第二个主要因素和接触面有。

He and his colleagues found that the softer the surface the smaller the splash.

他和同事发现，接触面越柔软，飞溅程度越小。该。

Both balloon and paper bag contain pressurized air pushing outagainst the sides.

气球和纸袋里都含有带压空气，这些空气向四周接触面上施压。

So you have to get a lot of air to pass over what is basically like a contact surface.

所以你必须让大量的空气通过类似于接触面的东西。

The mold base needs to lower the surface to guarantee enough contacting surface between the core and cavity blocks.

模需要降面保证动定模仁之间足够的接触面。

That's Kripa Varanasi, a mechanical engineer at the Massachusetts Institute of Technology who co-created LiquiGlide to battle the nefarious issue of interfaces.

这麻省理工学院的机械工程师克利潘·威瓦纳斯，为攻克接触面难题，威瓦纳斯与人合伙创立了LiquiGlide。

Her conclusion is that the reflection does indeed sometimes come from the interface between snow and ice, as it is supposed to. But not always.

她的结论反射有时确实雪和冰的接触面，应该如此，但不常发生。

Steel wool burns because these long strands have huge surface areas that are exposed and ready to react with the oxygen in the air.

钢丝烧得很快，因为这些长线有更大接触面暴露（在空气中），准备与空气中的氧发生反应。

LiquiGlide came about due to an infamous interface problem in the oil industry. Drilling oil unearths all types of crud, mucky sediment and minerals.

石油行业中有个讨厌棘手的接触面问题，LiquiGlide的成立正为了解决这一问题。石油钻探挖掘各类杂质、淤泥质沉积物和矿物。

This steel wool is basically just thinly shaved metal that's mostly iron, and the more fine, the more surface area the metal has, the easier it is to burn.

钢丝大概就削得很细的金属，大部分铁，并且更精纯，金属的接触面越大，越容易燃烧。

An interface is any spot or surface where two things meet. You're familiar with the physical forces creating friction and solid interfaces, like when a tire skids on a road.

两个物体相遇的任何点面即接触面。大家对物理力产生摩擦和固体界面比较熟悉，比如像轮胎在路上打滑。
