不少人看过啊,这是一部几乎没有情节的动作大片
And when we're looking at the probability density graphs, it doesn't make a difference, it's okay, It has no meaning for our actual plot there, because we're squaring it, so it doesn't matter whether it's negative or positive, all that matters is the magnitude.
它的概率密度图的时候,两者没什么区别,这是可以的,它对我们画这个图,没有什么意义,因为我们是取平方,所以它的正负,无所谓,只和幅值有关,但当我们说到。
It has a lot of plot and no action, so it's the other way around.
这部影片武打少情节多,和前一步刚好相反
