Clouds are formed from the evaporation of the oceans' water that is warmed by the Sun and rises high into the atmosphere, condensing in tiny droplets on minute particles of dust.
云是由海洋中的水分被太阳加热蒸发而形成的,这些水分上升到大气中,凝结成微小的水滴,附着于微小的尘埃颗粒。
Quantum mechanics is a highly successful theory: it supplies methods for accurately calculating the results of diverse experiments, especially with minute particles.
量子力学是一种非常成功的理论:它提供了精确计算各种实验结果的方法,特别适用于微小粒子方面。
The problem was caused by minute particles of dust getting in the disk drive.
问题是由进入到磁盘驱动器上的灰尘微粒引起的。
If he switched from gold to let's say iron, he also tried platinum, a number of different foils, he found that they count rate it still was 20 alpha particles per minute.
金箔的时候,计数率就变成零了,如果他把金换成比如说铁,他们还尝试了铂,还有一系列其他的箔片,他发现计数率还是每分钟。
So, what he detected was that there were 20 alpha particles per minute.
可以探测到20个alpha粒子,这个听上去很重要吗?
