Since the early days of the COVID-19 pandemic, public health officials have been concerned about larger particles from the coronavirus.

自疫情爆发初期，公共健康官员就一直在关注携带冠状病毒的大型微粒。

These suggestions are based on the idea that larger particles fall to the ground before they can travel very far.

大的颗粒物不能传播很远，会落到地上。

As larger particles sediment more quickly than smaller ones, there is a shift toward smaller particle sizes during transport.

由于较大的颗粒比较小的颗粒沉降得更快， 因此在运输过程中会向较小的颗粒尺寸转变。

The smaller ice particles are lighter, so they're constantly traveling upwards inside the cloud and colliding with larger ice particles, thus generating electric charges.

较小的冰粒子较轻，因此它们在云中不断向上移动，并与较大的冰粒子碰撞，从而产生电荷。

At that time, we were working at the European Organization for Nuclear Research at the world's largest particle collider, which collides protons, by the way.

当时我们在欧洲核能研究所工作，那里有世界上最大型的粒子对撞器。

" One possibility is that the place of the second touchdown was a hard bedrock and larger particles broke and entered the compartment, " Usui said.

" 可能第二次着陆的地方是一块坚硬的基岩，较大的碎块破裂后进入了舱内。"

Some of the most important include settling tanks to remove large particles, biological reaction tanks where microbes eat unwanted materials, and chemical disinfection processes that kill pathogens.

其中最为重要的步骤包括沉淀池中去除大颗粒，生物降解池中多余物质由微生物分解，以及化学消毒杀死病原体。

The Daphnia consumed these particles, and scientists found that, while the larger particles didn't seem to affect them, the smallest particles — around 50 nanometers — were deadly.

水蚤吃掉了这些颗粒，然后科学家发现，较大的颗粒似乎不会影响它们，但大约50纳米的那些小颗粒是致命的。

Nose hairs at the entrance of the nasal cavity get coated with that mucus and are able to trap large particles of dust and pollen as well as bacteria, forming tiny clumps of boogers.

在鼻腔入口处的鼻毛表面覆盖着这种粘液，它们会吸附大的灰尘颗粒、花粉和细菌，形成鼻屎。

Although they are similar to blood capillaries, lymphatic capillaries are more permeable, and therefore they're more prone to allow the passage of proteins or even larger particles such as bacteria and viruses.

尽管它们与血毛细血管相似，但淋巴毛细血管的渗透性更强，因此它们更容易使蛋白质甚至细菌和病毒等更大的颗粒通过。

" And you need these larger particles as a food source for larger creatures to evolve. Looking at our molecules it became clear … there was no food source for larger creatures. It solves a very old question" .

" 大型生物的进化需要颗粒较大的藻类作为食物来源。 观察这些分子后我们就可以明白，那时没有大型生物生存所需的食物来源。 这也解决了一个古老的问题。"

I have mentioned that atoms and molecules possess consciousness to a degree, as do electrons of course. The organizing principle of small particles into larger particles lies within the particles themselves, and is directed from within in all cases.

我已经提到，原子和分子在一定程度上拥有意识，当然电子也是如此。小粒子变成大粒子的组织原则在粒子本身之内，在任何情况下都是由内部引导的。
