r u really over him 你真的放下他了吗
I don't know what R&R really is now, I thought it's a prograss of Human civilization, but it might be a degeneration, for there are so many dancing hairy ape on the R&R stage nowadays.
我现在不知道摇滚到底是什么,我曾经认为那是人类文明的进步,但它也可能是退化,因为如今摇滚舞台上尽是些会跳舞的长毛猿。
Equally important, no other R&D unit in the GE network can claim sole credit, either, which begs the question: "Where was it really innovated?"
同样重要的是,通用电气系统中其它任何一个研发单位也不能如此居功,这就使下面的问题无法回答:“这到底是在哪里发明的呢?”
But, basically you don't really need to remember these formulas as long as you remember how to express r in terms of rho sine phi, and x equals r cos theta.
事实上你不用记住这些公式,只需要知道r=ρ*sinφ,而x=r*cosθ
R/Cv OK, so that means that this is really instead of -1 R over Cv. it's really gamma minus one.
现在,变成了γ
