依然有许多碰撞在发生，车辆在道路上打滑，所以我们仍然有大量的救援电话要处理。

We still have a number of crashes, vehicles spinning out, so we are still dealing with a high volume of calls.

当体系中浆液密度较高时，颗粒由于相互间的碰撞在表面能的作用下团聚成纺锤形的大颗粒。

When density of precipitated slurry is too high, because of the collision among particles, big spindly aggregates which are made of ultra-fines are born in reactor at the action of surface energy.

And so the photons hitting the wall actually put pressure on the wall, but the pressure is so low.

所以光子碰撞墙面,事实上在对墙加压，但只是压力很小。

If we get the pressure in there just right, we will allow for gas electron collisions and then we get the glow that ultimately was sent through the slits.

如果我们把气压设置在一个适当程度，把气体电子碰撞也算在里面,我们得到的炽热,最终将通过裂缝传送。
