”自己去google“就是你最好的解析了。
我再说一次:量子物理学认为,电子围绕原子核的运动并非运转, ...
By definition, atoms have no overall electrical charge. That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons. 这不是原子也可以分阴阳吗?
According to Einstein's theory of special relativity, as an electron's speed approaches the speed of light, from an observer's point of view its relativistic mass increases, thereby making it more and more difficult to accelerate it from within the observer's frame of reference. The speed of an electron can approach, but never reach, the speed of light in a vacuum, c. However, when relativistic electrons—that is, electrons moving at a speed close to c—are injected into a dielectric medium such as water, where the local speed of light is significantly less than c, the electrons temporarily travel faster than light in the medium. As they interact with the medium, they generate a faint light called Cherenkov radiation.[126]

自己看吧,我化学最差,大学本来选物理major的,但是挂科physics 150热力学,就转major了,再次重申我不精通物理。 |
