grand-total angular momentum 全总角动量
total angular momentum quantum number 总角动量矩数
total angular momentum j 总角动量j
They have a... together, a total momentum.
它们有一个,一个总动量。
So what is the total... the total momentum... let's give it a magnitude equals minus 1?
那么总的,总动量是多少呢。,使它的大小为负一?
Now, this is also 1 over m total times the total momentum, because I've all these momenta of these individual particles.
这是质量总和,乘以总动量,因为我得到这些动量,单个粒子的动量。
