One is dust and other heavy solid particles in the air.

一种是空气中的灰尘和其他固体颗粒。

The accretion process creates heat and heavier particles sink to the center of the accumulating mass.

增长的过程产生了热量，较重的粒子下沉到物质团的中心。

Heavier particles drop out first, but about five times further out than had been previously predicted.

较重的颗粒物最先下落，但仍然比之前预测到的距离远5倍以上。

The water sits undisturbed, allowing heavier particles to sink to the bottom.

水不受干扰，允许较重的颗粒沉入底部。

But when you spin it around really fast for a couple minutes, the centrifugal force pushes all the heaviest particles to the outside and they displace the less dense particles towards the middle.

但当你以高速旋转它几分钟之后，离心力把所有最重的粒子推到外面，它们把密度较小的粒子推向中间。

Susy, as this theory is known for short, got rid of the arbitrary assumptions by predicting a set of heavier (and as-yet-unseen) particles, a " superpartner" for each known fermion and boson.

Susy，这个理论的简称，通过预测一组更重的（和尚未见过的）粒子， 即每个已知费米子和玻色子的“超级伙伴” ，摆脱了武断的假设。
